Keypad Technologies for Demanding Environments

What is PushGate?

PushGate® is a patented push-button design that incorporates crisp tactile feedback similar to an electro-mechanical switch. Parts that wear out in typical tactile designs are eliminated and replaced with a magnet-armature design. The thin profile of PushGate® switches works without the scraping, flexing, or grinding that typical membrane switch components endure.
