Using our extensive experience and specialized production facilities, we have the ability to design and build custom switches that meet the unique specifications of our customers' needs. Our best sellers include our limit, precision, snap-acting, position, fuel flow and pressure switches.
Pressure Switches
Unison pressure switches are designed to perform in the harshest environments on the ground and in the air. Able to withstand temperatures ranging from -320 F to 1050 F and pressures up to 15,000 PSI, our precision- crafted switches are engineered to endure the hostile vibration, shock, pressure, and temperature conditions inherent in today's operating environments. Unison's snap-acting pressure switches offer greater set point stability, vibration resistance, over-pressure capability and cycle life. Our capabilities include absolute, gauge and differential pressure switches as well as differential gauges.
Limit Switches
Unison limit switches are custom designed for the rigors of your application. We offer a variety of actuation and de-actuation mechanisms, including rollers, plungers and buttons. Single-pole and multi-pole, single and double throw designs are also available. We specialize in switches for extremes in temperature, shock and vibration, corrosion and other hostile environmental conditions, as well as switches with longevity requirements.
