Use C437 for spst switching or C637 for spdt switching. Compensate for momentary surges in gas pressure with a restrictive orifice in inlet pressure channel on the models with pressure range of 1 to 26 in. wc (0.25 to 6.5 kPa). Resume operation by manually resetting when using lockout application models. Impede tampering and provide dust-resistant operation with enclosed setting. Increase strength of control diaphragm with Buna-N fiber-reinforced material. Clear glass cover allows observation of interior mechanism to aid in setting and checkout. Mercury switch provides visual indication of switch position.
