Lexan 8b35 Custom Labels Membrane Keypad Switch
Lexan 8b35 Custom Labels Membrane Keypad Switch
A keypad 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.keypad switches are primarily utilized with microprocessor based control systems found in medical, communication, instrumentation and appliance products.
