PSF100A SWITCH SERIES

SENSING PRESSURE | VACUUM | DIFFERENTIAL PRESSURE

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 / BENEFITS
  • 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 Standard (MIL-SPEC)
