The Simple Switch

Model P

General Purpose Pressure Switch

Series P switches are supplied with a cover for dust protection and a "BX" cable fitting to facilitate wiring. All Simple Switches may be ordered factory set, or may be easily adjusted in the field with the special wrench supplied with each switch.

Model C

Chassis Mount

The C model is only 2 1/2" x 1 7/8" x 1 1/4" and is ideally suited to installations inside junction boxes and equipment where space is limited, or where a cover is not necessary. This mount is available on all simple switches.

Model V

Vacuum Series

This V model utilizes the same reliable bourdon tube mechanism as our pressure switches. Specify setting and model PV (with cover) or model V (without cover).

Model R

Reset Switch

The model R is a reset pressure control switch designed for overload protection, cut off, or as a safety switch. Each switch automatically actuates at the pre-set pressure and remains until the button is pressed to reset the switch.
