ABSTRACT:
A thermostatic switch having a snap acting switch mounted for actuation between the side walls of a U-shaped bracket. A remote bulb-and-capillary thermal sensing capsule provides output motion to a lever for switch actuation. The lever has an edge portion pivotably engaging a reaction support tab on one bracket wall and a rotatable cam provides an adjustable reaction support on the opposite bracket wall. The cam slidably engages an arcuate groove on the lever to maintain the lever transversely and longitudinally positioned on the bracket for switch actuation.
