Magnetic Spring Contact Switch

NOSHOK Magnetic Spring Contact Switches (MSCS) are an excellent choice when an accurate pressure switch is required in addition to a high quality reliable pressure gauge.

These magnetic spring contact switches are fully adjustable because they are actuated by the pressure gauge pointer. A removable adjustment key also makes them tamper proof.

They operate with an extremely broad power supply, AC or DC up to 20V max. This feature allows them to be used virtually anywhere in the world in addition to very remote applications with only DC battery pack power available.

The standard units consist of (2) two magnetic spring contact switches. Switch (1) one is normally closed and switch (2) two is normally open with operation referenced on rising (or increasing) pressure. Either one or both switches may be used.




Typical applications include air compressors, gas compressors, hydraulic and pneumatic circuitry, die-cast machinery, plastic injection molding machinery, and anywhere accurate off/on switching capabilities based on pressure are required.

Magnetic Spring Contact Switches
Magnetic spring contact switches are available as a factory installed accessory on Models 40-105, 40-115, 40-400, 40-410, 40-901 and 40-911 for ranges from 0-60 psi through 0-30,000 psi. The lowest full scale pressure range it may be used on is 0-60 psi because of the increased load on the pointer and bourdon tube.

Special MSCS Options
The NOSHOK MSCS is pre-wired with a matching 4-pin connector in its standard configuration but is also available with an optional connector with 5 feet of 4-wire, color coded shielded cable.
