When the pressure is removed, the switch is disconnected. Its internal structure relies on the change of force on the metal spring to achieve on-off. It is widely used in digital cameras, household appliances, and mechanical equipment.

[0004] In order to achieve more functions and meet different application scenarios, some touch switches need to control the on and off of two circuits at the same time. However, the above touch switches can only control one group of circuits at the same time, which cannot meet the needs and there is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a dual-way touch switch to solve the problem in the above-mentioned related technology that some touch switches need to control the on and off of two circuits at the same time, but the above-mentioned touch switches can only control one group of circuits at the same time and cannot meet the demand.

[0007] By adopting the above technical solution, when the touch switch is used, one circuit is connected to the outer ends of the first pin and the second pin respectively, and the other circuit is connected to the outer ends of the third pin and the fourth pin respectively. When force is applied to press the button, the first reed and the second reed are elastically deformed, and the first pin and the second pin, the third pin and the fourth pin are connected. After the pressing stops, the first reed and the second reed are restored and the button is reset, so that the first pin and the second pin, the third pin and the fourth pin are disconnected. With this arrangement, the touch switch can control two circuits at the same time, thereby improving the application scope and applicable scenarios of the touch switch.

[0009] By adopting the above technical solution, when the button is pressed, the button squeezes the first elastic part and the second elastic part at the same time, so that the first elastic part abuts against the second pin, and the second elastic part abuts against the fourth pin. At this time, the circuit connected to the first pin and the second pin is connected, and the circuit connected to the third pin and the fourth pin is connected; when the button stops being pressed, the button automatically resets, and the first elastic part and the second elastic part also reset synchronously, so that the first elastic part is disconnected from the second pin, and the second elastic part is disconnected from the fourth pin. At this time, the circuit connected to the first pin and the second pin is disconnected, and the circuit connected to the third pin and the fourth pin is disconnected, thereby realizing synchronous control of the dual circuits.

Due to the setting of the number of the third contacts, the possibility of poor contact between the third contact and the second reed is reduced, thereby improving the performance of the touch switch.

[0024] Optionally, the inner end of the first pin is provided with a first bending portion that is bent toward the bottom side of the base and fixedly connected to the base, and the end of the bending piece away from the third pin is provided with a second bending portion that is bent toward the bottom side of the base and fixedly connected to the base.
