ABSTRACT:
A thermostatic switch has a thermostatic subassembly located on a header so that movable contacts engage and disengage complementary contacts mounted on the header in response to temperature change. A knurled stud part has an interference fit in a header bore and a nut threadedly engages the opposite end of the stud means and bears against the opposite side of the header. The nut is rotatable for drawing the knurled stud part into the header bore to the desired degree to precisely locate the subassembly relative to the header during switch manufacture and calibration. The interference fit of the knurled stud part in the header bore otherwise cooperates with the nut to prevent rotation or axial movement of the stud means in any direction in the header bore.
