Description
Technical Field
[0001] The utility model relates to the technical field of membrane switches, in particular to a press-type membrane switch. Background Art
[0002] Membrane switch is an operating system that integrates key functions, indicating elements, and instrument panels. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contact of the upper circuit deforms downward and contacts the plate of the lower circuit. When the finger is released, the contact of the upper circuit rebounds, the circuit is disconnected, and the loop triggers a signal. The membrane switch has a rigorous structure, beautiful appearance, and good sealing. It is moisture-proof and has a long service life. It is widely used in electronic communications, electronic measurement instruments, industrial control, medical equipment, automotive industry, smart toys, household appliances and other fields.
[0003] Due to the structure of the membrane switch, the trigger stroke of the membrane switch is particularly short. If the reset force of the membrane switch reset device is too large, it will be very difficult to press the membrane switch, thereby increasing the difficulty of operating the membrane switch. If the reset force of the membrane switch reset device is too small, it is easy to cause accidental touching of the membrane switch, which will still increase the difficulty of operating the membrane switch.
