Switch calibration mechanism.

摘要

In an electrical switch having a selectively variable operating point, the switch includes an adjustable calibrating member for selectively adjusting the operating point by moving in response to selective movement of a cam member. The mechanism includes a cam member that is mounted for selective rotation about a longitudinal axis and for movement axially along the axis responsive to rotation. A cam surface on the cam member cooperates with the calibrating member for adjustably moving same to adjust the switch operating point responsive to axial movement of the cam member by selectively rotating said cam member. The cam surface lies on the surface of a cone having a cone axis coincidental with the longitudinal axis.
