ABSTRACT:
A bimetal element operated indicator includes a bimetal carrying a current measuring winding and having a fixed end mounted on a housing, a dial supported on the housing and carrying scale indicia, and a pointer rotatably supported on a stud shaft mounted on the dial and having a driven end coupled with a driving end of the bimetal element such that the pointer is precisely aligned relative to the scale indicia on the dial to provide accurate indicating movement in response to deflection of the bimetal element with temperature change from current in the measuring winding.
