Abstract
A snap acting thermostatic disc assembly having a thermostatic disc element (20) responsive both to current and to ambient temperature is provided with an electrical contact (22) on a face surface on the disc element at one end thereof and a weld slug (24) at an opposite end of the disc element and has a fulcrum member (28, 28', 28') on the opposite face surface of the disc element in alignment with the weld slug. The fulcrum member is arranged to move the bending location of the disc element member away from the heat affected zone of the thermostatic metal caused by welding. In a second embodiment the snap acting disc element is used as an ambient temperature responsive control member.
