Detail Information

Description :

Membrane switch is a conductive keypad with unique exterior design, combines the overlay printing and electronic circuits and features with light, thin, short and tiny. All design can follow customer's specification. Materials such as TPU, PC and PET are in options.

TPU (Polyurethane) is a new eco friendly material which does not cause any damage to human body or environment. PET is resistant to strong acid and alkali, suitable for IPC and medical products use.

PC (Polycarbonate) is lower in price and suitable for home appliance. Membrane switches mostly apply to Information Appliance, Humanity machine interface (HMI), Remote Controller, Medical Device, Home Appliance, Handheld Device, Industrial Personal Computer (IPC), etc. We offer full range of design services, the experienced professional art designers will design perfect colorful drawing for overlay, also the circuit layout and mechanism dimension diagram base on customer's information.
