Introduction of membrane Switch
A membrane switch is a touch-sensitive device created by the printing, cutting, and laminating of
precision thin-film plastic materials. Low-voltage, low-current momentary electrical contact is made
and retained by applying finger-tip force to the front surface of the switch.
Membrane switch technology has become a reliable front panel solution where environmental
concerns or frequent cleaning are an issue. The sealed nature of the technology coupled with its
reliability and ability to offer tremendous aesthetic flexibility make it the solution of choice for many
industries.
