Product Bulletin Pressure Switches (high pressure - piston style) The MICO® Pressure Switches are designed specifically for use in hydraulic applications to monitor hydraulic pressure and either open or close an electrical contact at a predetermined pressure. ● Rugged heavy-duty industrial construction ● Pressure setting range from 250 PSI to 3500 PSI ● Resistant to high pressure spikes ● 10 million mechanical cycle life ● Fluid compatibility to suit most applications ● Optional gold contacts, lead lengths, and port sizes The piston style pressure switch can be wired for use in hydraulic applications where the electrical contacts are in the normally open (n/o) condition, normally closed (n/c) condition, or both. The three wire lead to the single pole double throw internal snap switch contains a black wire which is the common and always used, a green wire used for a normally open contact, and a red wire used for a normally closed contact. This switch can sense hydraulic pressure to 5000 psi. This document is intended to provide general information about MICO Products.

Fluid pressure is used to actuate a piston, which in turn forces against a spring retainer. As the pressure increases the retainer compresses the spring. When this occurs the floating disc moves away from the spring lever of the snap action switch, thus, contact transfer results. The MICO® Pressure Switch is a high pressure surge resistant switch specially designed for hydraulic applications when an electrical connection or disconnection is desired at a predetemined pressure. The pressure switch contains a single-pole, doublethrow (SPDT) snap action switch that is controlled by a...
