Abstract
A switch calibration mechanism having a cam member that is rotatable about a longitudinal axis and that moves along said axis responsive to such rotation. A cam surface on the cam member cooperates with a cam follower on a movable calibrating member to adjust the operating point of a switch during longitudinal movement of the cam member.
Claims18
In an electrical switch having a selectively variable operating point, said switch including an adjustable calibrating member for selectively adjusting said operating point by moving in response to selective movement of a cam member, said mechanism including a cam member that is mounted for selective rotation about a longitudinal axis and for movement axially along said axis responsive to rotation thereof, and a cam surface on said cam member cooperating with said calibrating member for adjustably moving same to adjust said switch operating point responsive to axial movement of said cam member by selectively rotating said cam member.
In an electrical switch having an adjustable calibrating member for selectively adjusting the switch operating point by moving in response to selective movement of an adjusting screw, said mechanism including a threaded adjusting screw having a longitudinal axis and being threadably mounted for selective rotation about said axis and for movement axially along said axis during rotation thereof, said screw having a tapered cam surface engaging said calibrating member for moving said calibrating member toward and away from said axis responsible to axial movement of said screw by selectively rotating said screw.
