PSF100A-3.0

## **Pressure Switches Miniature** 

## **Description** 

The rugged yet ultra-sensitive PSF100A pressure switch incorporates a patented dual diaphragm/dual contact design offering protection against false actuation due to shock and vibration 

## **Features** 

- Patented shock and vibration resistance 

- Miniature size, lightweight, low cost 

- Quick response time 

- Dependable long life (20+ million cycles) 

- Gold contact points (dual) 

- Rugged military standards (MIL-SPEC)
