Mechanical Pressure Switch

Mechanical Pressure Switch Introduction

Mechanical Pressure Switch is a small size and high performance pressure switch, it has the inner construction of

SPST connection and silver contact. The switch can be used in circuit control that the max current can be up to 16A. High quality Stainless steel diaphragm is dedicated to control equipment of high temperature and pressure with water vapor. Compact appearance make this switch suitable for devices the smaller internal that have installation space.

Mechanical Pressure Switch is used to regulate the tank pressure between two preset values on small (up to 175psi) electrically driven air compressors. They are available with an unloader valve, which prevents compressors from starting under load, and an auto-off disconnect lever for manual cut off the compressor. A four port manifold style is available which provides a means for easy mounting of valves and gauges.
