PushGate®
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.
Advantages of PushGate® Technology
- Crisp, consistent tactile feel
- Superior tactile feel that does not degrade over time
- Dependable performance over typical competitor products
- Durability and reliability
- Rated to over 30 million actuations
- More reliable than traditional metal dome membrane switches
- Eliminates material stress caused by bending and flexing of materials
- Temperature, chemical and vandal-resistant
- Environmentally sealed for use in harsh and wet environments
- Design Flexibility
- Easy to integrate with thiNcoder® rotor and other switch components
- Will work with either a rigid PCB or FPC
- Backlighting can be easily integrated. Full-key illumination possible with fiber optic, EL and LED backlighting
- Maintains firm tactile feel when backlighting is incorporated
