[0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 847,480, filed on May 14, 2019, the disclosure of which is incorporated herein by reference in its entirety. Background of the Invention

[0003] In a load control system, a standard mechanical switch (e.g., a decorative rocker switch, etc.) can be replaced by a more advanced load control device (such as a dimmer switch) that controls the amount of electricity transferred from an alternating current (AC) power source to an electrical load. This process typically requires disconnecting the old decorative rocker switch and removing it from the load control system, and connecting the new load control device to the electrical wiring. Usually, such processes must be performed by an electrical contractor or other experienced installer. The average consumer may feel uncomfortable completing the installation of the load control device. Therefore, there is a need for a load control system that can be installed in an existing device with a decorative rocker switch without any electrical work and is aesthetically pleasing. Summary of the Invention

[0004] As described herein, a remote control device for use in a load control system (e.g., to control an electrical load and / or a load control device) can be configured to be mounted on an installed mechanical switch having a rocker actuator. The mechanical switch can control whether power is transferred to the electrical load. The remote control device is installed without accessing the electrical wiring of the mechanical switch.

[0005] The remote control device can include a base and a control unit configured to be detachably attached to the base. The control unit can include a control interface and a wireless communication circuit. The control unit can cause the wireless communication circuit to transmit a control signal in response to a user input received via the control interface.

[0006] The base can be configured to be mounted above the rocker actuator of the mechanical switch. The base can include a frame, a coupling member, a biasing member, and / or a strap portion. The frame can be configured to secure the remote control device thereto. The frame can define an opening configured to receive a protruding portion of the rocker actuator therein. The frame can define a rear surface configured to abut the border of the mechanical switch. The biasing member can be configured to engage the rear surface of the panel of the mechanical switch. The panel can be configured to be mounted above the wall box of the mechanical switch. The biasing member can be configured to apply a force to the rear surface of the panel. The strap portion can be configured to attach the biasing member to the frame. The strap portion can be configured to extend through a gap between the border and the panel such that the frame is located on the front side of the panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figures 1 to 14 An example of a remote control device 100 that can be installed in a load control system such as a lighting control system is depicted. The load control system can include a mechanical switch 190, which can be in place prior to the installation of the remote control device 100, e.g., pre-existing in the load control system. As shown, the mechanical switch 190 can be a standard decorative rocker switch. The load control system can also include one or more electrical loads, such as lighting loads. The mechanical switch 190 can be coupled between an alternating current (AC) power source and one or more electrical loads in a series electrical connection.

[0028] The mechanical switch 190 may include a rocker actuator 192 that may be actuated to open and / or close one or more electrical loads. The mechanical switch 190 may include a bezel 193 surrounding the rocker actuator 192. An upper portion of the rocker actuator 192 may project from the bezel 193 when the electrical load is off (e.g., in a first orientation), and a lower portion of the rocker actuator 192 may project from the bezel 193 when the electrical load is on (e.g., in a second orientation, as shown in Figure 4 ), or vice versa. The mechanical switch 190 may include a yoke 194 capable of mounting the mechanical switch 190 to a structure ( Figure 4 ). For example, the yoke 194 may be fastened to a single-gang wall box installed in an opening in a structure (e.g., such as a wall, ceiling, etc.). As shown, the panel 160 may be fixed to the mechanical switch 190, e.g., to the yoke 194. The panel 160 may define a front surface 161 and an opposite rear surface 163. The front surface 161 may alternatively be referred to as the outer surface of the panel 160, and the rear surface 163 may alternatively be referred to as the inner surface of the panel 160. The panel 160 may define an opening 162 (e.g., a panel opening) therethrough having an inner surface 167 and configured to receive a portion of the mechanical switch 190. The panel 160 may be made of any suitable material (such as plastic). The remote control device 100 may be configured to be mounted above the rocker actuator 192 of the mechanical switch 190 (e.g., mounted to the rocker actuator 192, the bezel 193, and / or the panel 160).

[0029] The load control system may further include a load control device (not shown) electrically connected to one or more electrical loads (e.g., lighting loads). The load control device may include a load control circuit for controlling the intensity of one or more lighting loads between a low-end intensity (e.g., approximately 1%) and a high-end intensity (e.g., approximately 100%), and may include a wireless communication circuit. In an exemplary implementation, the load control device may be a dimmer switch electrically connected to one or more lighting loads. In another exemplary implementation, each of the one or more electrical loads may be a controllable light source (e.g., a screw-in light-emitting diode (LED) lamp), each of which may include a corresponding integrated load control circuit and a wireless communication circuit (e.g., the lighting load includes a corresponding load control device configured for wireless communication). It should be understood that the load control system is not limited to the exemplary load control devices described herein.

[0030] The remote control device 100 may include a control unit 110 (e.g., a control module) and a base 120 (e.g., a base component). The control unit 110 may be configured to be attached to the base 120. The control unit 110 may be mounted to the base 120. For example, the base 120 may be configured to mount the remote control device 100 above a mechanical switch 190. The base 120 may define a fixture 126 for removably securing the control unit 110 thereto. The fixture 126 may be configured to engage complementary features (e.g., Figure 2B the tab 114 shown in

[0031] ). The base 120 may alternatively be referred to as a base portion, a mounting frame, or a mounting assembly. The control unit 110 and the base 120 may be configured such that the control unit 110 can be removably attached to the base 120. The base 120 may be configured to be attached to a panel 160. For example, the base 120 may be configured to be mounted within a panel opening 162. In this regard, the remote control device 100 may be mounted above a mounted mechanical switch (such as the mechanical switch 190) without performing any electrical rewiring of the mechanical switch 190.

[0032] As Figure 1 shown in and FIG. 2, the control unit 110 may be rectangular in shape and elongated between the upper wall 121 and the lower wall 122. It should be understood that the control unit 110 is not limited to the rectangular geometry shown, and the control unit may alternatively be configured with other suitable geometries. According to the orientation of the control unit 110 shown, the upper wall 121 may be referred to as the upper end of the control unit 110, and the lower wall 122 may be referred to as the lower end of the control unit 110. The upper wall 121 and the lower wall 122 of the control unit 110 may also be referred to as the first end and the second end of the housing 111, respectively. The control unit 110 may include a printed circuit board 147 (e.g., a flexible printed circuit board or a rigid printed circuit board). The control circuit 110 (e.g., the housing 111) may define a void 128 (e.g., asFigure 2B as shown). The gap 128 can be configured to receive the printed circuit board 147 in an attached position. The gap 128 can be defined by an upper wall 121, a lower wall 122, and opposing side walls 123. The housing 111 can be made of any suitable material, such as plastic.

[0033] The actuating portion 112 can include a front surface 115 having an upper portion 116 and a lower portion 118. The actuating portion 112 can be configured to pivot about a central axis in response to actuation of the upper portion 116 and the lower portion 118. The control unit 110 can be configured to control an electrical load. For example, the control unit 110 can be configured to turn on the electrical load in response to actuation of the upper portion 116 and turn off the electrical load in response to actuation of the lower portion 118. The front surface 115 of the actuating portion 112 of the control unit 110 can define a user interface configured to receive input, such as a gesture, from a user of the remote control device 100. The user interface can be configured as a touch-sensitive surface (e.g., a capacitive touch surface) configured to receive (e.g., detect) input, such as a gesture, from a user of the control unit 110. For example, the printed circuit board 147 can include one or more capacitive touch areas or surfaces. The printed circuit board 147 can include one or more linear capacitive touch surfaces that face an inner surface of the actuating portion 112 when the printed circuit board 147 is disposed in the control unit 110. The front surface 115 of the actuating portion 112 can be configured to detect touches along the x-axis, the y-axis, or both the x-axis and the y-axis. The control unit 110 can also include a light bar 119 configured to be illuminated by one or more light sources (e.g., one or more LEDs). For example, the light bar 119 can be illuminated to visually display information to a user of the control unit 110. The front surface 115 of the actuating portion 112 can be actuated along the light bar 119 to adjust the amount of power delivered to the lighting load based on the position of the actuation.

[0034] The control unit 110 may further include a control circuit (e.g., a processor, not shown) and a wireless communication circuit (e.g., a radio frequency transceiver, not shown). The control unit 110 may be configured to convert one or more inputs (e.g., user inputs) from a user interface into corresponding control signals that can be used to control a load control device of a load control system. One or more inputs may be applied by touching or pressing an upper portion 116 and / or a lower portion 118 of the actuation part 112. For example, the control circuit may be configured to receive an input signal (e.g., an input signal corresponding to a user input) in response to actuation of the upper portion 116 and / or the lower portion 118 by a user of the remote control device 100. For example, the input signal received by the control circuit may be a corresponding control signal converted from an input at a control interface. The control circuit may be configured to generate a command that the user desires the control unit 110 to execute in response to the input signal, the input signal being generated in response to actuation of the upper portion 116 and / or the lower portion 118. The control unit 110 may be configured to cause the wireless communication circuit to transmit one or more control signals including the command generated by the control circuit.

[0035] The control circuit may be configured to cause the wireless communication circuit to transmit corresponding commands corresponding to inputs and / or gestures received at the upper portion 116 and / or the lower portion 118. For example, the remote control device 100 may be used to transmit wireless signals, such as radio frequency (RF) signals, to a load control device, one or more electrical loads, and / or a central processor of a load control system. During a configuration process of the load control system, the remote control device 100 may be associated with a load control device and one or more electrical loads.

[0036] The control circuit may be configured to cause the wireless communication circuit to transmit corresponding commands corresponding to the interpreted gestures received at a capacitive touch surface. For example, the remote control device 100 may be operable to transmit wireless signals, such as RF signals, to a load control device, one or more electrical loads, and / or a central processor of a load control system. During a configuration process of the load control system, the remote control device 100 may be associated with a load control device and one or more electrical loads. An example of a configuration process for associating a remote control device with a load control device is described in more detail in U.S. Patent Publication No. 2008 / 0111491, commonly assigned and titled RADIO-FREQUENCY LIGHTING CONTROL SYSTEM, published on May 15, 2008, the entire disclosure of which is incorporated herein by reference.

[0037] The light bar 119 of the control unit 110 can be configured to provide a visual indication of commands issued by the remote control device 100. For example, the control circuit can be configured to, upon receiving a gesture indicating a command to change the amount of power delivered to an electrical load (such as a command to dim a lighting load), indicate the amount of power delivered to the electrical load by temporarily lighting multiple LEDs, where the amount of power corresponds to the desired amount of power (e.g., the desired dimming level of the lighting load). In such examples, the control circuit can be configured to cause the LEDs to light simultaneously, light sequentially in some or little overlapping fashion before dimming, or light in other ways as needed. The control unit 110 can be configured to be attached to the base 120, where the light bar 119 is located on a predetermined side of the control unit 110 (e.g., the right side of the control unit as shown in Figure 1 ), such that the light bar 119 can be lit to indicate the amount of power currently delivered to the electrical load.

[0038] The control unit 110 shown can be battery-powered. For example, the control unit 110 can include a battery 180 (e.g., a button battery as shown). The battery 180 can be placed in electrical communication with a circuit mounted to the printed circuit board 147, such as to power the capacitive touch area, the control circuit, the wireless communication circuit, and / or other circuits of the control unit 110. The control unit 110 can include a battery holder 170. The battery holder 170 can be configured to hold the battery 180 therein. The battery holder 170 can be configured to be mounted within a void 128 of the control unit 110. The battery holder 170 can be configured to electrically connect the battery 180 to a circuit mounted to the printed circuit board 147.

[0039] The base 120 can be configured to position the control unit 110 in front of the panel 160 (e.g., the front surface 161). For example, the base 120 can be configured to bias the control unit 110 towards the panel 160. The base 120 can be configured to accommodate a mechanical switch having a bezel and / or a rocker actuator that extends various distances beyond the panel 160 (e.g., the front surface 161). As shown, the base 120 can include a frame 130, a biasing member 140, and a strap portion 150. The frame 130 can be configured to receive the control unit 110. The frame 130 can be configured to attach (e.g., removably attach) the control unit 110 to the base 120. The frame 130 can define a first end wall 132, a relative second end wall 134, and opposite side walls 136 extending from respective ends of the first end wall 132 to corresponding ends of the second end wall 134. According to the shown orientation of the base 120, the first end wall 132 can be referred to as the upper end wall of the frame 130, and the second end wall 134 can be referred to as the lower end wall of the frame 130. The frame 130 can define a rear surface 138 configured to abut the bezel 193 of the mechanical switch 190.

[0040] As Figure 2AAs shown, the frame 130 can be configured to receive the projection of the rocker actuator 192. For example, the frame 130 can define a frame opening 135 ( Figure 4 ) configured to receive the projection of the rocker actuator 192. The frame opening 135 can be defined by a first end wall 132, a second end wall 134, and opposing side walls 136.

[0041] The biasing member 140 can be configured to pull the frame 130 (e.g., the rear surface 138) against the bezel 193 of the mechanical switch 190. The biasing member 140 can be a connector configured to engage a surface (e.g., the rear surface 163) of the panel 160. For example, the biasing member 140 can be configured to removably secure the base 120 to the panel 160. The biasing member 140 can be configured to apply a force to the rear surface 163 of the panel 160. For example, applying a force to the rear surface 163 of the panel 160 can bias the frame 130 against the bezel 193 of the mechanical switch. That is, the biasing member 140 can be configured such that when the remote control device 100 is mounted above the rocker actuator 192 of the mechanical switch 190, the rear surface 138 of the frame 130 abuts the bezel 193 of the mechanical switch 190. The biasing member 140 can include spring contacts 142, spring arms 144, and a spring support 146. The spring contacts 142 can extend between the respective spring arms 144 at the top and bottom of the biasing member 140. The spring contacts 142 can be configured to engage the rear surface 163 of the panel 160. For example, the spring contacts 142 can abut the rear surface 163 of the panel 160 above and below the panel opening 162. The spring contacts 142 can be configured to apply a force to the rear surface 163 of the panel 160. The spring contacts 142 can be configured to push the spring support 146 into the wall box. For example, when the spring contacts 142 abut the rear surface 163 of the panel 160, the biasing member 140 can push the spring support 146 into the wall box until the ribbon portion 150 is taut. When the ribbon portion 150 is taut, the spring support 146 can float on either side of the mechanical switch 190 (e.g., inside the wall box). Since the spring contacts 142 extend between the spring arms 144 at the top and bottom of the biasing member 140, the spring arms 144 and the spring support 146 can remain aligned when the base 120 is mounted on the mechanical switch 190. In addition, the spring support 146 can contact (e.g., abut) the side of the bezel 193 of the mechanical switch 190, which can help align the base 120 during installation and thus simplify the installation process of the remote control device 100.

[0042] The spring support 146 can be configured to float at the side of the mechanical switch 190. For example, the spring support 146 can extend into the wall box in which the mechanical switch 190 is mounted. The spring support 146 can extend as far as possible into the wall box within the range allowed by the strip portion 150. For example, the length of the strip portion 150 can determine how far the spring support 146 extends into the wall box. The spring support 146 can be without attachments. When the spring contact 142 abuts the rear surface 163 of the panel 160, the spring support 146 can float within the wall box (e.g., not attached to the mechanical switch 190, the panel 160, and / or the wall box).

[0043] As shown, the spring support 146 can extend into the wall box on the opposite side of the mechanical switch 190. The spring arm 144 can extend from the spring support 146 to the spring contact 142. For example, the spring arm 144 can be configured to bias the spring contact 142 away from the spring support 146. The spring arm 144 can be compliant such that the spring contact 142 is configured to bias against the rear surface 163 of the panel 160. Each of the spring supports 146 can define a fixture 148. The fixture 148 can be configured to hold the respective spring arm 144. For example, the fixture 148 can be configured to releasably secure the spring arm 144 to the spring support 146. The biasing member 140 can define a flat portion 145. For example, each of the spring arms 144 can define a flat portion 145. The flat portion 145 can connect the respective spring arm 144. The flat portion 145 can be configured to be received by the respective fixture 148. The flat portion 145 can be configured to abut the spring support 146, for example, when received within the fixture 148.

[0044] The strip portion 150 can be configured to attach the biasing member 140 to the frame 130. The strip portion 150 can be configured to be received by a gap 165 (FIG. 2) defined between the frame border 193 and the panel 160. For example, the strip portion 150 can extend through the gap 165 such that the frame 130 is located on the front side of the panel 160. The strip portion 150 can be a thin deformable material. For example, the strip portion 150 can be a polyester film, such as a mylar sheet. The strip portion 150 can be configured to be bent such that the base 120 can extend through the gap 165 between the frame border 193 and the panel 160.

[0045] The strip portion 150 can be configured to connect the biasing member 140 to the frame 130. The strip portion 150 can be fixed to the frame 130. For example, the strip portion 150 can be configured to wind around a part of the frame 130. The part of the frame 130 wound by the strip portion 150 can have a reduced cross-section. For example, the outer periphery of the strip portion 150 winding around the part of the frame 130 can be substantially the same as other parts of the frame 130. The frame 130 can define one or more (e.g., a plurality of) studs 131. The studs 131 can be configured to fix the strip portion 150 (e.g., the end of the flexible material) to the frame 130. For example, the studs 131 can be received by corresponding apertures (not shown) in the strip portion 150. It should be understood that although the strip portion 150 is shown in the figures winding around the frame 130, the strip portion 150 can be fixed to the frame 130 by alternative means (e.g., such as using fasteners, welds, adhesives, etc.).

[0046] The strip portion 150 can be configured to connect the spring support 146 to the frame 130. The strip portion 150 can be fixed to the spring support 146. For example, the strip portion 150 can be configured to wind around a part of the spring support 146. The spring support 146 can define one or more (e.g., a plurality of) studs 141. The studs 141 can be configured to fix the strip portion 150 (e.g., the end of the flexible material) to the biasing member 140. For example, the studs 141 can be received by corresponding apertures (not shown) in the strip portion 150. It should be understood that although the strip portion 150 is shown in the figures winding around the spring support 146, the strip portion 150 can be fixed to the spring support 146 by alternative means (e.g., such as using fasteners, welds, adhesives, etc.).

[0047] The strip portion 150 can include adhesive wings (not shown). The adhesive wings can be configured to adhere to the side of the border 193 of the mechanical switch 190. The adhesive wings can be configured to fix the strip portion 150 to the mechanical switch 190.

[0048] The base 120 can be configured to be mounted on the panel 160 before fixing the panel 160 to the mechanical switch 190. For example, the panel 160 can be removed from the mechanical switch 190 and the base 120 can be fixed to the panel 160. The base 120 can be configured to be inserted into the panel opening 162. For example, the frame 130 can be inserted through the panel opening 162. When the frame 130 is inserted through the panel opening 162, the spring contact 142 can abut the rear surface 163 of the panel 160. The base 120 and the panel 160 can then be mounted above the mechanical switch 190 such that the spring support 146 extends into the wall box.

[0049] Figures 15 to 18 Depicting a remote control device (e.g., Figure 1Another example base 220 of the remote control device 100 shown in FIG. 2. The base 220 can be configured to position the control unit (e.g., Figure 1 and the control unit 110 shown in FIG. 2) in front of a panel (e.g., Figures 1 to 4 , Figure 13 and Figure 14 the panel 160 shown in). For example, the base 220 can be configured to bias the control unit towards the panel. The base 220 can be configured to accommodate a mechanical switch having a bezel and / or a rocker actuator that extends various distances beyond the panel (e.g., the front surface of the panel). As shown, the base 220 can include a frame 230 (e.g., the frame 130 shown in FIGS. 2 to Figure 14 ), a biasing member 240, and a strap portion 250. The frame 230 can be configured to receive the control unit. The frame 230 can be configured to attach (e.g., detachably attach) the control unit to the base 220. The frame 230 can define a first end wall 232, an opposite second end wall 234, and opposite side walls 236 extending from the respective ends of the first end wall 232 to the corresponding ends of the second end wall 234. According to the orientation of the base 220 shown, the first end wall 232 can be referred to as the upper end wall of the frame 230, and the second end wall 234 can be referred to as the lower end wall of the frame 230. The frame 230 can define a rear surface 238 configured to abut the bezel of the mechanical switch (e.g., the bezel 193 of the mechanical switch 190 shown in FIGS. 2 and Figure 4 ).

[0050] The frame 230 can be configured to receive a protruding portion of the rocker actuator of the mechanical switch (e.g., the rocker actuator 192 shown in FIGS. 2 and Figure 4 ). For example, the frame 230 can define a frame opening 235 configured to receive the protruding portion of the rocker actuator. The frame opening 235 can be defined by the first end wall 232, the second end wall 234, and the opposite side walls 236.

[0051] The biasing member 240 can be configured to pull the frame 230 (e.g., the rear surface 238) against the bezel of the mechanical switch. The biasing member 240 can be a connector configured to couple the base 220 to the panel. For example, the biasing member 240 can be configured to engage a surface of the panel (e.g., the rear surface 163 of the panel 160). For example, the biasing member 240 can be configured to detachably fix the base 220 to the panel 260. The biasing member 240 can be configured to apply a force to the rear surface of the panel (e.g., the rear surface 163 of the panel 160). For example, applying a force to the rear surface of the panel can bias the frame 230 (e.g., the rear surface 238) against the bezel of the mechanical switch.

[0052] The biasing member 240 may include spring contacts 242, spring arms 244, and an elongate portion 246. The spring contacts 242 may extend between respective spring arms 244 at the top and bottom of the biasing member 240. The spring contacts 242 may be configured to engage the rear surface of the panel. For example, the spring contacts 242 may abut the rear surface of the panel above and below an opening in the panel (e.g., the panel opening 162 shown in Figure 4 ). The spring contacts 242 may be configured to apply a force to the rear surface of the panel. The elongate portion 246 may extend between the spring arms 244. The spring contacts 242 may be configured to push the elongate portion 246 into the wall box. For example, when the spring contacts 242 abut the rear surface of the panel, the biasing member 240 may push the elongate portion 246 into the wall box until the ribbon portion 250 is taut. When the ribbon portion 250 is taut, the elongate portion 246 may float on either side of the mechanical switch (e.g., within the wall box). Since the spring contacts 242 extend between the spring arms 244 at the top and bottom of the biasing member 240, the spring arms 244 and the elongate portion 246 may remain aligned when the base 220 is mounted on the mechanical switch. Additionally, the elongate portion 246 may contact (e.g., abut) the side of the bezel of the mechanical switch, which may assist in aligning the biasing member 240 during installation and thus simplify the installation process of the remote control device.

[0053] The elongate portion 246 may be configured to float at the side of the mechanical switch. For example, the elongate portion 246 may extend into the wall box in which the mechanical switch is mounted. The elongate portion 246 may extend as far into the wall box as permitted by the ribbon portion 250. For example, the length of the ribbon portion 250 may determine how far the elongate portion 246 extends into the wall box. The elongate portion 246 may be without attachments. When the spring contacts 242 abut the rear surface of the panel, the elongate portion 246 may float within the wall box (e.g., not attached to the mechanical switch, the panel, and / or the wall box).

[0054] The spring arms 244 may be configured to bias the spring contacts 242 away from the elongate portion 246. The spring arms 244 may be compliant such that the spring contacts 242 are configured to bias against the rear surface of the panel. The elongate portion 246 may connect the respective spring arms 244.

[0055] The ribbon portion 250 may be configured to attach the biasing member 240 to the frame 230. The ribbon portion 250 may be configured to be received by a gap defined between the bezel and the panel. For example, the ribbon portion 250 may extend through the gap such that the frame 230 is located on the front side of the panel. The ribbon portion 250 may be a thin deformable material. For example, the ribbon portion 250 may be a polyester film such as a mylar sheet. The ribbon portion 250 may be configured to be bent such that the base 220 may extend through the gap between the bezel and the panel.

[0056] The strip portion 250 can be configured to connect the biasing member 240 to the frame 230. The strip portion 250 can be fixed to the frame 230. For example, the strip portion 250 can be configured to wind around a portion of the frame 230. The portion of the frame 230 wound by the strip portion 250 can have a reduced cross-section. For example, the outer periphery of the strip portion 250 that winds around the portion of the frame 230 can be generally the same as other portions of the frame 230. The frame 230 can define one or more (e.g., a plurality of) posts 231. The posts 231 can be configured to fix the strip portion 250 (e.g., the end of the flexible material) to the frame 230. For example, the posts 231 can be received by corresponding apertures (not shown) in the strip portion 250. It should be understood that although the strip portion 250 is shown in the figures as winding around the frame 230, the strip portion 250 can be fixed to the frame 230 by alternative means (e.g., such as using fasteners, welds, adhesives, etc.). The strip portion 250 can be fixed to the biasing member 240. For example, the strip portion 250 can be attached to the biasing member 240 using adhesives, crimps, clamps, and / or alternative means (e.g., such as using fasteners, welds, etc.).

[0057] The strip portion 250 can include adhesive wings (not shown). The adhesive wings can be configured to adhere to the side of the bezel of the mechanical switch. The adhesive wings can be configured to fix the strip portion 250 to the mechanical switch.

[0058] The base 220 can be configured to be mounted on the panel before the panel is fixed to the mechanical switch. For example, the panel can be removed from the mechanical switch and the base 220 can be fixed to the panel. The base 220 can be configured to be inserted into a panel opening. For example, the frame 230 can be inserted through the panel opening. When the frame 230 is inserted through the panel opening, the spring contacts 242 can abut the rear surface of the panel. The base 220 and the panel can then be mounted on the mechanical switch such that the elongate portion 246 extends into the wall box.

[0059] Figure 19 Depicts another exemplary base 320 of a remote control device (e.g., Figure 1 and the remote control device 100 shown in FIG. 2). The base 320 can be configured to position the control unit of the remote control device (e.g., Figure 1 and the control unit 110 shown in FIG. 2) in front of a panel (e.g., Figures 1 to 4 , Figure 13 and Figure 14 the panel 160 shown in). For example, the base 320 can be configured to bias the control unit towards the panel. The base 320 can be configured to accommodate a mechanical switch having a bezel and / or a rocker actuator that extends various distances beyond the panel (e.g., the front surface of the panel).

[0060] As shown, the base 320 can include a frame 330 (e.g., the frame 130 as shown in FIGS. 2 to Figure 14 or the frame 230 as shown in Figure 15 and Figure 16 and a coupler 340. The frame 330 can be configured to receive a control unit. The frame 330 can be configured to attach (e.g., detachably attach) the control unit to the base 320. The frame 330 can define a first end wall 332, an opposite second end wall 334, and opposite side walls 336 extending from respective ends of the first end wall 332 to corresponding ends of the second end wall 334. According to the orientation of the base 320 shown, the first end wall 332 can be referred to as the upper end wall of the frame 330, and the second end wall 334 can be referred to as the lower end wall of the frame 330. The frame 330 can define a rear surface 338 configured to abut a border of a mechanical switch (e.g., the border 193 of the mechanical switch 190 as shown in FIGS. 2 and Figure 4 ).

[0061] The frame 330 can be configured to receive a projecting portion of a rocker actuator of the mechanical switch (e.g., the rocker actuator 192 as shown in FIGS. 2 and Figure 4 ). For example, the frame 330 can define a frame opening 335 configured to receive the projecting portion of the rocker actuator. The frame opening 335 can be defined by the first end wall 332, the second end wall 334, and the opposite side walls 336.

[0062] The coupler 340 can be configured to pull the frame 330 (e.g., the rear surface 338) against the border of the mechanical switch. The coupler 340 can be a coupler configured to engage a surface of a panel (e.g., the rear surface 163 of a panel such as Figure 2A and Figure 4 ). For example, the coupler 340 can be configured to detachably secure the base 320 to the panel. The coupler 340 can be configured to apply a force to a surface of the panel. For example, the coupler 340 can be configured to apply a force to an inner surface of the panel (e.g., the inner surface 167 defined by a panel opening 162 as shown in Figure 4 ) and / or a rear surface (e.g., the rear surface 163 of a panel such as Figure 2A and Figure 4 ). Applying a force to a surface of the panel can bias the frame 330 (e.g., the rear surface 338) against the border of the mechanical switch.

[0063] The coupling member 340 may include one or more (e.g., a plurality of) flaps 342. Each of the flaps 342 may be wedge-shaped, having a thickness that increases (e.g., gradually increases) in a direction away from the rear surface 338 of the frame 330. The flaps 342 may be configured to wedge into the gap between the bezel and the panel (e.g., the gap 165 as shown in FIG. 2). For example, each of the flaps 342 may include a silicone-based material (e.g., silicone), and the silicone-based material is configured to deform when wedged into the gap between the bezel and the panel. The flaps 342 may be thicker at the end away from the frame 330. The gap may define a front portion near the front surface of the panel and a rear portion near the rear surface of the panel. The end 343 of each of the flaps 342 (e.g., near the frame 330 and / or the strip portion 344 of the coupling member 340) may wedge into the rear portion of the gap, such that the base 320 is removably fixed to the panel. When the end 343 of each flap 342 wedges into the rear portion of the gap, the distal portion 345 of the flap 342 may extend beyond the rear surface of the panel. When the end 343 of the flap 342 wedges into the rear portion of the gap, the flap 342 may apply a force to the inner surface and / or the rear surface of the panel, such that the base 320 is coupled to the panel. The flaps 342 may be configured to extend into the wall box on opposite sides of the mechanical switch. For example, the distal portion 345 of the flap 342 may float behind the rear surface of the panel on opposite sides of the mechanical switch. It should be understood that the flaps 342 are not limited to Figure 19 the geometry shown. Alternatively, the flap 342 may define another shape having a thickness that gradually increases from the end 343 to the distal portion 345. In another alternative, the flap 342 may define a constant thickness (e.g., a substantially constant thickness) from the end 343 to the distal portion 345.

[0064] The coupling member 340 may be configured to be attached to the frame 330. For example, the frame 330 may define one or more (e.g., a plurality of) posts 331. The posts 331 may be configured to fix the coupling member 340 (e.g., the end of the flexible material) to the frame 330. For example, the posts 331 may be received by corresponding apertures (not shown) in the coupling member 340. It should be understood that although the coupling member 340 is shown in the figures as being wound around the frame 330, the coupling member 340 may be fixed to the frame 330 by alternative means (e.g., such as using fasteners, welds, adhesives, etc.).

[0065] The coupling member 340 may include a strip portion 344 (e.g., a plurality of strip portions 344, such as Figure 19as shown). The strip portion 344 can be configured to attach the connector 340 to the frame 330. For example, each of the plurality of sheets 342 can be attached to the frame 330 via a respective strip portion 344. The strip portion 344 can define a corresponding aperture configured to receive the stud 331. For example, the strip portion 344 can be wound around the frame 330. The strip portion 344 can be attached to the sheet 342. For example, the strip portion 344 can be wound around the sheet 342. At least a portion of the strip portion 344 can be received by a gap defined between the bezel and the panel. For example, the strip portion 344 can (e.g., at least partially) extend through the gap such that the frame 330 is located on the front side of the panel, the sheet 342 is wedged (e.g., at least partially wedged) into the rear portion of the gap, and the distal portion 345 of the sheet 342 is located on the rear side of the panel. The strip portion 344 can be a thin deformable material. For example, the strip portion 344 can be a polyester film, such as a Mylar sheet. The strip portion 344 can be configured to be bent such that the base 320 can extend into the gap between the bezel and the panel.

[0066] The base 320 can be configured to be mounted to the panel before the panel is fixed to the mechanical switch. For example, the panel can be removed from the mechanical switch and the base 320 can be fixed to the panel. The base 320 can be configured to be inserted into a panel opening. For example, the frame 330 can be inserted through the panel opening. When the frame 330 is inserted through the panel opening, the sheet 342 can abut the inner surface of the panel opening and / or the rear surface of the panel (e.g., when the sheet 342 is deformed). The base 320 and the panel can then be mounted on the mechanical switch such that the distal end of the sheet 342 extends into the wall box.

[0067] It should be understood that the bases 120, 220, 320 are not limited to the respective configurations shown and described herein, and the respective components of the bases can alternatively be configured with other suitable geometries. For example, the bases 120, 220, 320 can alternatively be configured such that the outer wall defines a larger or smaller area. By way of illustration, the outer walls of the bases 120, 220, 320 can be configured to define an area smaller than the footprint of the rocker actuator 192 of the mechanical switch 190.

[0068] It should be further understood that the bases 120, 220, 320 may alternatively be configured to allow releasable attachment of a control unit having a geometry different from that of the control unit shown. By way of illustration, the bases 120, 220, 320 may alternatively be configured to allow releasable attachment of a control unit having a corresponding footprint (e.g., area) that is larger than the footprint of the bases 120, 220, 320, such that the control unit surrounds the frames 130, 230, 330 and / or at least partially obscures the frames 130, 230, 330. Additionally, for example, the bases 120, 220, 320 may alternatively be configured to allow releasable attachment of a control unit other than the control unit 110 shown, such as a control unit having a different geometry and / or defining another type of user interface.

[0069] It should also be further understood that configuring the bases 120, 220, 320 of the remote control device such that the frames 130, 230, 330 of the bases 120, 220, 320 are biased against the border 193 of the mechanical switch 190 to which the bases 120, 220, 320 are mounted may provide one or more advantages. By way of example, configuring the bases in this manner may limit or reduce the need to account for variables in one or more of the lateral (e.g., side-to-side), longitudinal (e.g., up and down), and transverse (e.g., along a direction perpendicular to the outer surface of the panel) directions, which may be exhibited by the respective dimensions or geometries (e.g., rocker height) of different mechanical switches and / or the mounting conditions of the mechanical switches. Additionally, by referencing the border of the mechanical switch for the bases, rather than, for example, the outer surface of the panel, the need to account for a frame surrounding the border of the mechanical switch may be eliminated, as the border dimensions may vary with different switches.

[0070] It should also be further understood that the remote control device 100 shown and described herein may provide a simple retrofit solution for an existing switch control system and may simplify the installation of a load control system or enhance the installation of an existing load control system. A load control system incorporating the remote control device 100 may provide energy savings and / or advanced control features, for example, without the need for any electrical rewiring and / or without the need to replace any existing mechanical switches.

[0071] It should also be further understood that the load control systems into which the exemplary remote control device 100 can be integrated are not limited to the above-described exemplary load control devices and / or electrical loads. For example, the load control systems into which the remote control device 100 can be integrated may include one or more of the following: a dimming ballast for driving a gas discharge lamp; an LED driver for driving a light-emitting diode (LED) light source; a dimming circuit for controlling the intensity of a lighting load; a screw-in lamp fixture including a dimming circuit and an incandescent or halogen lamp; a screw-in lamp fixture including a ballast and a compact fluorescent lamp; a screw-in lamp fixture including an LED driver and an LED light source; an electronic switch, a controllable circuit breaker, or other switching device for turning an appliance on and off; a plug-in load control device, a controllable electrical outlet, or a controllable power strip for controlling one or more plug-in loads; a motor control unit for controlling a motor load, such as a ceiling fan or an exhaust fan; a drive unit for controlling electric window treatments or a projection screen; one or more electric interior and / or exterior window blinds; a thermostat for a heating and / or cooling system; a temperature control device for controlling a set point temperature of a heating, ventilation, and air conditioning (HVAC) system; an air conditioner; a compressor; an electric baseboard heater controller; a controllable damper; a variable air volume controller; a fresh air intake controller; a ventilation controller; a hydraulic valve in one or more radiators for a radiant heating system; a humidity control unit; a humidifier; a dehumidifier; a water heater; a boiler controller; a pool pump; a refrigerator; a freezer; a television and / or a computer monitor; a camera; an audio system or amplifier; an elevator; a power supply; a generator; a charger, such as an electric vehicle charger; an alternative energy controller; etc.
