ABSTRACT:
Disclosed are a switch structure and a calibration technique that facilitate the rapid and substantially automatic calibration of a switch of the type that responds to changes in an environmental parameter (e.g., a thermostatic switch). An abutment member (which will serve as the calibrated stop) is supported for preliminary movement with a switch movable member (e.g., a bimetallic arm) and is supported in a bracket which is capable of gripping the abutment member but which is initially prevented from doing so by the action of a member that stresses the bracket. The last-mentioned member is deformable (e.g., it melts) at a desired value of the environmental parameter, thereby resulting in the bracket gripping the abutment member (which then defines a stop for the switch's movable member).
