Polyester(PET) LED Membrane Switch, Key Membrane Switch Customized Design
Polyester, polycarbonate and polyurethane typically make up the components of a membrane switch panel.
Internally, the switching mechanisms are via metal domes or conductive shorting pads.
Further enhancements include surface mount LEDs, water clear widows, dead fronts, back-lighting with optic fibre or electroluminescence and solid mounting plates.
Terminations to the PCB can be via Berg connectors and Nicomatic connectors or designed to fit Zif connectors.
Membrane switches and keypads are a fully customisable solutions for Human – Machine Interface (HMI) requirements.
Each product we design and manufacture is unique and has its own requirement regarding environmental, mechanical, electrical and physical appearance properties.
With our decades of experience, Our Industries is able to help you through the specification process to make sure your products HMI solution is suited perfectly.
