Pressure & Limit Switches

Pressure Switches

Unison pressure switches are designed to perform
in the harshest environments on the ground and in
the sky. To withstand temperatures from -320F to
1050F and pressures up to 15,000 PSI, our precision- crafted switches are designed to endure the hostile vibration, shock, pressure, and temperature conditions inherent in today's electro-mechanical operating environments. Unison's snap-acting pressure switches offer greater set point stability, vibration resistance, over-pressure capability, and cycle life.

Our pressure switch capabilities include:

  • Absolute pressure switches.
  • Gauge pressure switches.
  • Differential pressure switches and gauges.

    Limit Switches
    Unison limit switches are custom designed for the rigors of your application. A variety of actuation and de-actuation mechanisms are available including rollers, plungers and buttons. Single-pole and multi-pole, single and double throw designs are also available.

    Our specialties include switches for very high temperature, high shock and vibration, corrosive and other environmental extremes, and long life requirements.
