Waterproof membrane switch keypad,SMD LEDs & resistors onto the circuit layer and backlight membrane switch is available.

Membrane Switch Specification:

Operation voltage: < 35 VDCOperation current: <100 mAOperation force: 30~500gOperation temperature: -35C~+85CContact bounce: 3~30msContact resistacne: <100 ohmsOpen circuit resistance: < 100 Meg ohmsLife expectency(min): 5x100, 000Storage temperature: -35C~+70CUsual Material: PC & PET

We can use surface-mounted-technology to attach SMD LEDs&resistors onto the circuit layer. Backlight membrane switch is available too.
