Abstract
A pressure switch has a housing with a mounting bracket and a flexible diaphragm defining a wall of the pressure sensing cavity in the housing. Movement of the diaphragm operates an electric switch. The diaphragm is spring biased and an adjustment arm is frictionally mounted in a pair of guide surfaces on the mounting bracket. The arm contacts a cap on one end of the bias spring and is movable in the guide surfaces for adjusting the position of the spring cap for calibration. The mounting bracket is mounted to the housing by inserting a lug on the bracket in a recess in the housing and crimping a folded tab on the bracket to engage another recess in the housing. In another embodiment using a housing of all molded plastic, the adjustment arm frictionally engages a slot molded in the housing and is moved in the slot for calibration.
