Keypads are an economical alternative to conventional mechanical switches, and are used extensively in a wide range of electronic applications and industries. They are manufactured from polyester or incorporate a printed circuit board as the circuit layer. Overlay and spacer can be provided for assembly to your PCB if required. They are supplied with a flexible tail for connection while PCB based designs can incorporate connectors on the rear for the connection of ribbon cable or similar.
Keypad design can incorporate backlighting in the form of EL(Electroluminescent) or Lumitex Fibre-Optic Panels. Due to the ability to integrate these technologies within the switch structure, button graphics can be lit even when using metal domes for tactile feedback.
Membrane Keypads also offer the option to integrate devices such as led's and resistors within the assembly. Integration by such will reduce the time spent aligning led's behind a graphic panel.
As the front surface of the keypad is essentially an overlay panel, all the design options that are available for overlays apply to membrane keypads.
We can supply the keypads pre-assembled to backing panels manufactured from steel, aluminium polycarbonate or PETG which inturn can also incorporate mounting holes, standoffs and studs if required.
