ABSTRACT:
A one piece member rests against a cam surface at a first end and against an adjustable pivot at a second end, biased thereagainst by an integral cantilever spring of said member, the distal end of which is interlocked in a deflected position to a hook formed in a housing. One end of a bimetal strip is riveted to the second end of the one piece member, the position of the other end of the bimetal strip being determined by manual adjustment of the pivot and the cam.
