Description

Technical Field

[0001] The utility model relates to the technical field of membrane switches, in particular to a membrane switch with replaceable labels. Background Art

[0002] Membrane switch is an operating system that integrates key functions, indicating elements, and instrument panels. 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. Membrane switches are moisture-proof and have a long service life. They are widely used in electronic communications, electronic measurement instruments, industrial control, medical equipment, and the automotive industry.

[0003] Membrane switches are usually integrated into a control panel, but when mass production is carried out, it is necessary to perform proofing tests on the design drawings. This test method usually requires the operator to connect a single membrane switch to the design circuit. Since there are too many membrane switches connected, the membrane switches need to be numbered, but most of these membrane switches used for testing are usually printed with numbers that cannot be changed. This is very inconvenient for designers to perform proofing tests, and they often mix up the numbers of the membrane switches, which prolongs the proofing test time and reduces the efficiency of the proofing test.
