LED Membrane Switch Back Light Membrane Switch Metal Dome With Holes
Membrane switches are flex circuits that turn devices off and on like a regular switch.
Traditional switches usually consist of plastic pieces and copper for conductivity. Membrane switches, on the other hand, feature circuits printed directly onto their base. They go on the front of devices, where users can access them.
Membrane switches are affordable, versatile, reliable, and effective. Membrane switches have lower conductivity than some switches and are perfect for many different low-power applications.
We make membrane switches for devices like: security keypads, cell phone touch screens, aircraft control panels, airport kiosks, personal gaming devices, tablets, home appliances, and more.
Provide us with your specifications and we will help you create a suitable design optimized for your application.
