Mechanical Pressure Switches
Rugged electromechanical pressure switches that provide reliable on/off control or alarm signalling at preset pressure setpoints in industrial process systems.

Mercoid mechanical pressure switches use proven diaphragm, bellows or piston sensing elements to actuate snap-action electrical contacts at a defined pressure setpoint. They are engineered for dependable, long-life operation in tough plant conditions.
Available in a range of pressure spans, set-point adjustments and enclosure styles, these switches serve as pump control, alarm and shutdown devices across utility and process applications.
- Diaphragm, bellows or piston sensing elements for varied pressure ranges
