Abstract
The circuit control unit of the present invention comprises a piston-type pressure responsive member or gauge wherein one end of the piston extends beyond the gauge body and carries an actuator which is movable with the piston. A circuit control member is mounted for actuation by the actuator for controlling an external electrical circuit in response to changes in fluid pressure as detected by the pressure responsive member. Where desired, an indicator may be mounted in fixed relationship with the pressure responsive member, providing means for visibly indicating the pressure of the fluid and the position of the piston with respect to the pressure responsive member.
