[0002] With the increasing use of motorized curtains, most mechanical curtain switches on the market currently use a combination of two-position reset switches. One switch controls the motor's forward rotation, and the other controls its reverse rotation. When the motor is running, the switch needs to be pressed down; releasing it stops the motor. There is no interlocking function between the two switches; simultaneous operation can damage the motor. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a curtain switch device that achieves double reset, which is easy to operate, safe, and widely applicable.

[0004] To achieve the above objectives, the curtain switch device of this utility model that realizes double reset is as follows: The main features of this double-reset curtain switch device are that the device includes a movable contact, an outgoing terminal, an incoming terminal, a lever, a reset spring, and a metal button. The metal button is mounted on the lever, and the two reset springs are respectively mounted on the bottom sides of the lever. The movable contact is mounted on the incoming terminal and supports rotation. The metal button drives the lever to rotate, and together with the lever nozzle, drives the movable contact to rotate, thus making the incoming terminal and the outgoing terminal connected.

[0005] Preferably, the movable contact includes a silver contact, a V-shaped groove, and a central plane. The V-shaped groove is a V-shaped structure with a central depression. The two silver contacts are respectively installed at both ends of the V-shaped groove, and the two central planes are respectively located on both sides of the V-shaped groove. The input terminal has two movable contact slots, and the central plane contacts the plane of the movable contact slot on the input terminal, so that the movable contact is held in the middle position.

[0006] Preferably, the lever includes a return spring guide post, a dial guide cylinder, a lever rotation shaft, and a metal button connector.

[0022] To more clearly describe the technical content of this utility model, the following description is provided in conjunction with specific embodiments.

[0023] This utility model discloses a curtain switch device that achieves double reset, including a movable contact piece 3, an output terminal 5, an input terminal 6, a lever 9, a reset spring 10, and a metal button 17. The metal button 17 is mounted on the lever 9, and the two reset springs 10 are respectively mounted on the bottom sides of the lever 9. The movable contact piece 3 is mounted on the input terminal 6 and supports rotation. The metal button 17 drives the lever 9 to rotate, and together with the dial 12, drives the movable contact piece 3 to rotate, so that the input terminal 6 and the output terminal 5 are connected.

[0024] In a preferred embodiment of this utility model, the movable contact 3 includes a silver contact 31, a V-shaped groove 32, and a central plane 33. The V-shaped groove 32 is a V-shaped structure with a central depression. The two silver contacts 31 are respectively installed on both ends of the V-shaped groove 32, and the two central planes 33 are respectively located on both sides of the V-shaped groove 32. The inlet terminal 6 has two movable contact slots 61. The central plane 33 contacts the plane of the movable contact slots 61 on the inlet terminal 6, so that the movable contact 3 is held in the middle position.

[0025] In a preferred embodiment of this utility model, the lever 9 includes a reset spring guide post 91, a lever guide cylinder 92, a lever rotation shaft 93, and a metal button connector 94. The reset spring guide post 91 is located below both ends of the lever guide cylinder 92, the lever rotation shaft 93 is located on the side of the lever guide cylinder 92, the metal button connector 94 is located in the middle of the lever guide cylinder 92, and the metal button 17 is installed in the metal button connector 94.

[0026] In a preferred embodiment of the present invention, the metal button 17 is further provided with a lever fixing shaft 171, which is located on both sides of the metal button 17.

[0027] In a preferred embodiment of the present invention, the device further includes an indicator light cover 7, an indicator light assembly 8, a light-transmitting plate 13, an upper housing 14, a plastic frame 15, and a metal panel 16. The indicator light cover 7 is mounted on the upper housing 14, the indicator light assembly 8 is mounted between the indicator light cover 7 and the upper housing 14, the metal panel 16 is mounted on the plastic frame 15, and the light-transmitting plate 13 is mounted on the plastic frame 15.

[0028] In a preferred embodiment of the present invention, the metal panel 16 is provided with a lever hole 161 and an indicator light transmission hole 162.

[0029] This utility model discloses a curtain switch with an all-metal panel and metal button 17, which is a structure device that can be reset at both ends.

[0030] This utility model discloses a device with reset functions at both ends, using a movable contact 3 with a larger swing angle, and using an all-metal button and a fully enclosed metal panel, with an indicator light on the metal panel to show the switch operation status.

[0031] This invention provides a method for controlling the opening and closing of curtains.

[0032] Pressing the metal button 17 causes the lever 9 to rotate, which, together with the dial 12, causes the movable contact 3 to rotate, thus enabling the connection between the inlet terminal 6 and the outlet terminal 5.

[0033] When the metal button 17 is pressed, the return spring 10 on one side is compressed and stored, while the return spring 10 on the other side does not move. When the metal button 17 is released, the return spring 10 drives the lever 9 to rotate, which in turn drives the movable contact 3 to rotate, thereby disconnecting the inlet terminal 6 from the outlet terminal 5.

[0034] When lever 9 returns to the middle position and continues to rotate, the return spring 10 on the other side is compressed and will prevent lever 9 from rotating, thus keeping lever 9 in the middle position.

[0035] The middle plane 33 on the movable contact 3 is a plane that contacts the plane of the movable contact slot 61 on the incoming terminal 6, making it easy for the movable contact 3 to be held in the middle position.

[0036] The wires of the indicator light assembly 8 are led out from the housings 2 and 3 to the outside, and can be connected to the inlet terminal 6 and outlet terminal 5 of the switch to indicate the working status of the switch, or to the corresponding terminals on the load to indicate the working status of the load.

[0037] In a specific embodiment of this utility model, the all-metal panel and buttons are in a horizontal position when not in use, resulting in an excellent appearance. When one side of the metal button 17 is pressed, the button drives the lever 9 to rotate, the return spring 10 on the downward side is compressed, the dial on the lever 9 drives the movable contact 3 to swing, the movable contact 3 connects the corresponding outgoing terminal 5 with the incoming terminal 6, and the outgoing terminal 5 on the other side is in the off state.

[0038] When the button is released, the lever 9 rotates under the action of the reset spring 10. The dial on the lever 9 drives the movable contact 3 to swing, and the movable contact 3 separates the corresponding outgoing terminal 5 from the incoming terminal 6.

[0039] When lever 9 is rotated to the middle position, the return spring 10 on the other side is stressed, preventing lever 9 from continuing to rotate and preventing the switch on the other side from operating.

[0040] Both outgoing terminals 5 have corresponding indicator light assemblies 8. By wiring according to the specified terminals, they can be used to display the operating status of the corresponding switches.

[0041] To ensure the reliability and safety of the curtain's operation, a lever 9 that can be reset at both ends is used. The swing angle of the lever 9 is increased to prevent it from swinging to the other side during reset, which could cause malfunctions. A metal button 17 is inserted into and fixed to the middle of the lever 9, which can then actuate the lever 9.

[0042] This technical solution is an instantaneous switch. The metal button 17 and the lever 9 are rigidly connected. When there is no external force input, the metal button 17 and the lever 9 remain in the middle position. At this time, the movable contact 3 is also in the middle position, and the input and both output terminals are in a disconnected state. Pressing the metal button 17 causes the lever 9 to rotate, which in turn drives the movable contact 3 to rotate, connecting the input and output terminals. After releasing the metal button 17, the lever 9 rotates under the action of the return spring 10, driving the movable contact 3 to rotate, and the input and output terminals are immediately disconnected.
