Description

Technical Field

[0001] The utility model relates to the technical field of membrane switches, in particular to a touch-on keyboard membrane switch. Background Art

[0002] The 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 contacts of the upper circuit deform downward and contact and conduct with the plates of the lower circuit. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the loop triggers a signal. The membrane switch has a rigorous structure, beautiful appearance, good sealing, moisture resistance, and 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] The existing touch-on membrane switch has the following disadvantages when in use: since the contact point of the touch-on membrane switch is usually printed with a conductor on a film substrate, the conductor is directly integrated with the top film. During daily use, nails and external mechanical bumps can easily cause surface wear of the membrane switch. For the touch-on membrane switch, the wear of the surface film at the touch position will directly affect the sensitivity of the pressure touch. For this reason, we propose a touch-on keyboard membrane switch. Utility Model Content
