[0033] Some embodiments of the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which some but not all embodiments of the present disclosure are shown. In fact, these disclosures may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

[0034] As used herein, terms such as "front," "rear," "top," and the like are used for explanation purposes in the examples provided below to describe the relative positions of certain components or portions of components. In addition, in view of this disclosure, it will be apparent to one of ordinary skill in the art that the terms "substantially" and "approximately" indicate that the referenced element or associated description is accurate within applicable engineering tolerances.

[0035] As used herein, the term "comprising" means including, but not limited to, and should be interpreted in the manner in which it is commonly used in a patent context. The use of broader terms such as "including," "comprising," and "having" should be understood as support for narrower terms such as "consisting of," "consisting essentially of," and "consisting substantially of."

[0036] The phrases "in one embodiment," "according to one embodiment," and the like generally mean that a particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure, and may be included in more than one embodiment of the present disclosure (importantly, such phrases are not necessarily referring to the same embodiment).

[0037] The word “example” or “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other implementations.

[0038] The terms "electronically coupled" or "in electronic communication with..." in this disclosure may refer to two or more electrical components (e.g., but not limited to, example processing circuits, communication modules, input / output modules, memories) and / or (one or more) circuits that are connected by wired means (e.g., but not limited to, wires or traces) and / or wireless means (e.g., but not limited to, wireless networks, electromagnetic fields) so that electronic indications, signals, or the like data and / or information (e.g., electronic indications, signals) can be transmitted to and / or received from the electronically coupled electrical components and / or (one or more) circuits.

[0039] The term "switch" in the present disclosure may refer to an electrical component, a limit switch, or an electromechanical device that can be configured to connect or disconnect a conduction path in a circuit so as to interrupt or divert the current flowing along the conduction path. Example switches can be used in various applications to control circuits. For example, an example switch may include a bridge to a conducting contact. In various applications, when the bridge and the corresponding contacts are in a closed state (i.e., in contact with each other), current can pass between them. In contrast, when the bridge and the corresponding contacts are in an open state (i.e., not in contact with each other), no current passes between them.

[0040] If the specification states that a component or feature "may", "can", "might", "should", "will", "preferably", "likely", "typically", "optionally", "for example", "often" or "might" (or other such language) be included or have a property, the particular component or feature is not necessarily included or has that property. Such a component or feature may optionally be included in some embodiments, or may be excluded.

[0041] Various example embodiments address exemplary technical issues associated with visualizing the useful life of a switch. As will be appreciated by those skilled in the art, switches may be replaced periodically, for example, according to a predetermined schedule. In some examples, switches may therefore be replaced before they have reached the end of their useful life. Thus, waste is associated with premature replacement, and as a result, in some examples the use of the switch is not optimized. Therefore, there is a need to determine and visualize the remaining useful life of a switch.

[0042] To address at least these exemplary issues and other issues, the example switches described herein improve the use of the switch by providing a visualization of the remaining useful life of the example switch in some examples. For example, the switch can include an indicator for the remaining useful life of the switch. In some examples, the switch can further include a controller component configured to determine the remaining useful life of the switch, and in some examples, the controller component can be configured to control the indicator to illuminate with a corresponding color, or otherwise provide a signal or indication based on the remaining useful life of the switch.

[0043] Reference now Figure 1A and Figure 1B , provides an example diagram of an example switch 100 according to some example embodiments described herein. Figure 1A and Figure 1B As illustrated in FIG. 1 , the example switch 100 may include a first terminal 101 a , a second terminal 101 b , a first contact 102 a electrically connected to the first terminal 101 a , and a second contact 102 b electrically connected to the second terminal 101 b .

[0044] In some embodiments, the example switch 100 may further include a third terminal 101c, a fourth terminal 101d, a third contact 102c electrically connected to the third terminal 101c, and a fourth contact 102d electrically connected to the fourth terminal 101d.

[0045] In some embodiments, the example switch 100 can further include an actuator 103 and a guide element 104. For example, the actuator 103 can be constrained and / or guided to move through a hole (e.g., a slot, a groove, or the like) of the guide element 104. In some examples, the actuator 103 can include a pin 103a, a bridge 103b fixed to the pin 103a, and a spring 103c. For example, the spring 103c can be positioned adjacent to the pin 103a and can operate to facilitate movement of the actuator 103. For example, the actuator 103 can be configured to move vertically (e.g., in the y direction).

[0046] In some embodiments, the guide element 104 may be positioned adjacent to one end of the pin 103a.

[0047] In some examples, the first terminal 101a and the second terminal 101b may be normally open (NO) terminals. For example, the first terminal 101a and the second terminal 101b may be normally open so that no current can flow between the first terminal 101a and the second terminal 101b until the bridge 103b of the actuator 103 connects the first contact 102a and the second contact 102b.

[0048] In some examples, the third terminal 101c and the fourth terminal 101d may be normally closed (NC) terminals. For example, the third terminal 101c and the fourth terminal 101d may be normally closed so that current can flow between the third terminal 101c and the fourth terminal 101d until the bridge 103b of the actuator 103 is disconnected from the third contact 102c and the fourth contact 102d.

[0049] In some examples, actuator 103 can be configured to move vertically (eg, in the y-direction) to conduct at least one of the NO terminal and the NC terminal.

[0050] In some examples, such as Figure 1A As shown in , when the actuator 103 is pressed, the bridge 103b can contact the first contact 102a and the second contact 102b, so that the bridge 103b of the actuator 103 conducts the NO terminal (or the first contact 102a and the second contact 102b). In some examples, such as Figure 1B As shown in , when the actuator 103 is released, the bridge 103b may contact the NC terminal (or the third contact 102c and the fourth contact 102d), so that the bridge 103b of the actuator 103 conducts the NC terminal (or the third contact 102c and the fourth contact 102d).

[0051] In some examples, a repeatable switch action (eg, pressing and releasing) may be performed by pressing actuator 103 and releasing actuator 103 .

[0052] In some embodiments, the example switch 100 may further include a controller component 150, such as a printed circuit board assembly (PCBA), to communicate with the first contact 102a, the second contact 102b, the third contact 102c, and the fourth contact 102d. The example PCBA may be or include epoxy, ceramic, alumina, LCP, combinations thereof, and / or the like. For example, a wire may be used to electrically connect the first contact 102a, the second contact 102b, the third contact 102c, and the fourth contact 102d to the PCBA.

[0053] In some embodiments, the controller assembly 150 can be configured to measure a first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) when the actuator 103 is pressed. Figure 1A As shown in , the controller assembly 150 may be configured to measure a first contact resistance when the actuator 103 is pressed and the bridge 103 b of the actuator 103 conducts the NO terminal (or the first contact 102 a and the second contact 102 b ).

[0054] In some embodiments, the controller assembly 150 can be configured to determine a remaining useful life of the example switch 100 based on the first contact resistance.

[0055] In some examples, the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) can be within a first range. The first range can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. For example, the first range can be 0-45mΩ. In some examples, the remaining service life of the example switch 100 can be within a range based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. In some examples, when the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) is within the first range, the remaining service life can be from about 1000K to about 1500K.

[0056] In some examples, the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) can be within a second range. The second range can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. For example, the second range can be 45mΩ-100mΩ. In some examples, the remaining service life of the example switch 100 can be within a range based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. In some examples, when the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) is within the second range, the remaining service life can be approximately 500k.

[0057] In some examples, the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) can be within a third range. The third range can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. For example, the third range can be 100mΩ-1000mΩ. In some examples, the remaining service life of the example switch 100 can be within a range based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. In some examples, when the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) is within the third range, the remaining service life can be approximately 100k.

[0058] Additionally, and / or alternatively, in some embodiments, the controller assembly 150 may be configured to measure a second contact resistance between the NC terminals (or the third contact 102c and the fourth contact 102d) when the actuator 103 is released. Figure 1B As shown in , the controller assembly 150 may be configured to measure the second contact resistance when the actuator 103 is released and the bridge 103 b of the actuator 103 conducts the NC terminal (or the third contact 102 c and the fourth contact 102 d ).

[0059] In some examples, the second contact resistance between the NC terminals (or the third contact 102c and the fourth contact 102d) can be within a first range. The first range can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. For example, the first range can be 0-45mΩ. In some examples, the remaining service life of the example switch 100 can be within a range based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. In some examples, when the second contact resistance between the NC terminals (or the third contact 102c and the fourth contact 102d) is within the first range, the remaining service life can be in the range from about 1000K to about 1500K.

[0060] In some examples, the second contact resistance between the NC terminals (or the third contact 102c and the fourth contact 102d) can be within a second range. The second range can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. For example, the second range can be 45mΩ-100mΩ. In some examples, the remaining service life of the example switch 100 can be within a range based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. In some examples, when the second contact resistance between the NC terminals (or the third contact 102c and the fourth contact 102d) is within the second range, the remaining service life can be approximately 500k.

[0061] In some examples, the second contact resistance between the NC terminals (or the third contact 102c and the fourth contact 102d) can be within a third range. The third range can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. For example, the third range can be 100mΩ-1000mΩ. In some examples, the remaining service life of the example switch 100 can be within a range based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. In some examples, when the second contact resistance between the NC terminals (or the third contact 102c and the fourth contact 102d) is within the third range, the remaining service life can be approximately 100k.

[0062] In some embodiments, the example switch 100 may further include an indicator 160 that is configured to be in electrical communication and / or coupled to the controller assembly 150. In some examples, the indicator 160 may include one or more light emitting diodes ("LEDs"), laser emitting diodes, and / or the like. For example, the controller assembly 150 may control the indicator 160 to illuminate with a corresponding color based on the remaining useful life of the example switch 100. Alternatively or additionally, other sound emitting devices or displays may be used, such as speakers, screens, or the like.

[0063] In some examples, in an instance where the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) is within a first range, the controller component 150 can control the indicator 160 to illuminate with a first color. For example, the first color can be green. In some examples, in an instance where the second contact resistance between the NC terminal (or the third contact 102c and the fourth contact 102d) is within a first range, the controller component 150 can control the indicator 160 to illuminate with a first color.

[0064] In some examples, in an instance where the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) is within the second range, the controller component 150 can control the indicator 160 to illuminate with a second color. For example, the second color can be orange. In some examples, in an instance where the second contact resistance between the NC terminal (or the third contact 102c and the fourth contact 102d) is within the second range, the controller component 150 can control the indicator 160 to illuminate with a second color.

[0065] In some examples, in an instance where the first contact resistance between the NO terminal (or the first contact 102a and the second contact 102b) is within the third range, the controller component 150 can control the indicator 160 to illuminate with a third color. For example, the third color can be yellow. In some examples, in an instance where the second contact resistance between the NC terminal (or the third contact 102c and the fourth contact 102d) is within the third range, the controller component 150 can control the indicator 160 to illuminate with a third color.

[0066] Reference now Figure 2A and Figure 2B , provides an example diagram of an example switch 200 according to some example embodiments described herein. Figure 2A and Figure 2B As illustrated in FIG. 1 , the example switch 200 may include a first terminal 201 a , a second terminal 201 b , a first contact 202 a electrically connected to the first terminal 201 a , and a second contact 202 b electrically connected to the second terminal 201 b .

[0067] In some embodiments, the example switch 200 may further include a third terminal 201c, a fourth terminal 201d, a third contact 202c electrically connected to the third terminal 201c, and a fourth contact 202d electrically connected to the fourth terminal 201d.

[0068] In some embodiments, the example switch 200 can further include an actuator 203 and a guide element 204. For example, the actuator 203 can be constrained to move through a hole (e.g., a slot, a groove, or the like) of the guide element 204. In some examples, the actuator 203 can include a pin 203a, a bridge 203b fixed to the pin 203a, and a spring 203c. For example, the spring 203c can be positioned adjacent to the pin 203a and can operate to facilitate movement of the actuator 203. For example, the actuator 203 can be configured to move vertically (e.g., in the y direction).

[0069] In some embodiments, the guide element 204 may be positioned adjacent to one end of the pin 203a.

[0070] In some examples, the first terminal 201a and the second terminal 201b may be NO terminals. For example, the first terminal 201a and the second terminal 201b may be normally open so that no current can flow between the first terminal 201a and the second terminal 201b until the bridge 203b of the actuator 203 conducts the first contact 202a and the second contact 202b.

[0071] In some examples, the third terminal 201c and the fourth terminal 201d may be NC terminals. For example, the third terminal 201c and the fourth terminal 201d may be normally closed, so that current can flow between the third terminal 201c and the fourth terminal 201d until the bridge 203b of the actuator 203 is disconnected from the third contact 202c and the fourth contact 202d.

[0072] In some examples, actuator 203 can be configured to move vertically (eg, in the y-direction) to conduct at least one of the NO terminal and the NC terminal.

[0073] In some examples, such as Figure 2A As shown in , in an instance where the actuator 203 is pressed, the bridge 203b may contact the NO terminal (or the first contact 202a and the second contact 202b), so that the bridge 203b of the actuator 203 conducts the NO terminal (or the first contact 202a and the second contact 202b). In some examples, such as Figure 2B As shown in , in an instance where the actuator 203 is released, the bridge 203b can make contact with the NC terminal (or the third contact 202c and the fourth contact 202d), so that the bridge 203b of the actuator 203 conducts the NC terminal (or the third contact 202c and the fourth contact 202d).

[0074] In some examples, a repeatable switch action (eg, pressing and releasing) may be performed by pressing actuator 203 and releasing actuator 203 .

[0075] In some embodiments, the example switch 200 may further include a controller assembly 250, such as a printed circuit board assembly (PCBA), to communicate with the first contact 202a, the second contact 202b, the third contact 202c, and the fourth contact 202d. The example PCBA may be or include epoxy, ceramic, alumina, LCP, combinations thereof, and / or the like. For example, a wire may be used to electrically connect the first contact 202a, the second contact 202b, the third contact 202c, and the fourth contact 202d to the PCBA.

[0076] In some embodiments, the controller component 250 can be configured to count the number of times the actuator 203 is pressed. For example, the controller component 250 can record the number of historical presses that the actuator 203 may have been pressed. In some examples, each time the actuator 203 is pressed, the number of historical presses can increase by one.

[0077] In some embodiments, the example switch 200 can further include a sensor 206 positioned adjacent to the actuator 203. In some examples, the sensor 206 can sense and / or detect the actuator 203 in instances where the actuator 203 is pressed.

[0078] In some examples, sensor 206 can be a photoelectric switch. For example, sensor 206 can include a transmitter 206a and a receiver 206b. For example, transmitter 206a can operate by generating a light beam (e.g., an electromagnetic light beam, a visible light beam, an infrared light beam, and / or the like) and directing the light beam to receiver 206b. For example, receiver 206b can receive the light beam from transmitter 206a and detect any interruption of the light beam in an instance where actuator 203 is pressed.

[0079] For example, Figure 2A As shown in , in an instance where actuator 203 is pressed, one end of pin 203a of actuator 203 can be positioned in beam path 206c between emitter 206a and receiver 206b so that an interruption of the beam from emitter 206a to receiver 206b can be detected.

[0080] For example, Figure 2B As shown in , in an instance where the actuator 203 is released, one end of the pin 203a of the actuator 203 can be positioned outside the light beam path 206c between the transmitter 206a and the receiver 206b so that an interruption of the light beam from the transmitter 206a to the receiver 206b is not detected.

[0081] In some examples, the sensor 206 can be in communication and / or electrically coupled to the controller assembly 250 to count the number of times the actuator 203 is pressed. As described herein, the historical number of presses can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like.

For example, the transmitter 301 can operate by generating a light beam (e.g., an electromagnetic light beam, a visible light beam, an infrared light beam, and / or the like) and directing the light beam to the receiver 302. For example, the receiver 302 can receive the light beam from the transmitter 301 and detect any interruption of the light beam.

[0092] In some embodiments, the transmitter 301 and the receiver 302 may be positioned side by side along the optical path 303 of the light beam.

[0096] In some embodiments, the example switch 400 can further include an actuator 403 and a guide element 404. For example, the actuator 403 can be constrained to move through a hole (e.g., a slot, a groove, or the like) of the guide element 404. In some examples, the actuator 403 can include a pin 403a, a bridge 403b fixed to the pin 403a, and a spring 403c. For example, the spring 403c can be positioned adjacent to the pin 403a and can operate to facilitate movement of the actuator 403. For example, the actuator 403 can be configured to move vertically (e.g., in the y direction).

[0097] In some embodiments, the guide element 404 can be positioned adjacent to one end of the pin 403a.

[0098] In some examples, the first terminal 401a and the second terminal 401b may be NO terminals. For example, the first terminal 401a and the second terminal 401b may be normally open, so that no current can flow between the first terminal 401a and the second terminal 401b until the bridge 403b of the actuator 403 turns on the NO terminal (or the first contact 402a and the second contact 402b).

[0099] In some examples, the third terminal 401c and the fourth terminal 401d may be NC terminals. For example, the third terminal 401c and the fourth terminal 401d may be normally closed, so that current can flow between the third terminal 401c and the fourth terminal 401d until the bridge 403b of the actuator 403 is disconnected from the NC terminal (or the third contact 402c and the fourth contact 402d).

[0100] In some examples, actuator 403 can be configured to move vertically (eg, in the y-direction) to conduct at least one of the NO terminal and the NC terminal.

[0102] In some examples, such as Figure 4B As shown in , in an instance where the actuator 403 is released, the bridge 403b may contact the NC terminal (or the third contact 402c and the fourth contact 402d), so that the bridge 403b of the actuator 403 conducts the NC terminal (or the third contact 402c and the fourth contact 402d).

[0106] In some embodiments, the counting module 406 can be configured to count the number of times the bridge 403b can contact the NO terminal (or the first contact 402a and the second contact 402b). For example, the controller component 450 can record the number of historical conduction times that the actuator 403 has been pressed so that the bridge 403b contacts the NC terminal (or the first contact 402a and the second contact 402b). In some examples, each time the actuator 403 is pressed, the historical conduction number can increase by one.

[0107] Additionally or alternatively, in some embodiments, the counting module 406 can be configured to count the number of times the bridge 403b contacts the NC terminal (or the third contact 402c and the fourth contact 402d). For example, the controller component 450 can record the number of historical conduction times that the actuator 403 has been released, so that the bridge 403b contacts the NC terminal (or the third contact 402c and the fourth contact 402d). In some examples, each time the actuator 403 is released, the historical conduction number can be increased by one. As described herein, the historical conduction number can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like. Similarly, the remaining service life can be derived based on predetermined data, can be learned such as via supervised or unsupervised learning, can be derived based on test statistics, and / or the like.

[0110] In some examples, the historical turn-on times may be within a third range. For example, the third range may be 1500k-2000k. For example, the remaining useful life of the example switch 400 may be within a range from about 0 to about 500K.

[0111] In some embodiments, the example switch 400 can further include an indicator 460 that is configured to be in electrical communication and / or coupled with the controller assembly 450. In some examples, the indicator 460 can include one or more light emitting diodes (“LEDs”), laser emitting diodes, and / or the like.
