Abstract
Abstract A cam operated electrical switch construction having a rotatable cam, an electrical switch provided with a moving plunger and a cam follower construction for operating the plunger in response to rotation of the cam relative to the cam follower construction. The cam follower construction has a support pivotally mounted relative to the cam and plunger. A cam follower is carried by the support and a pair of rotatable adjusting members are carried by the support for adjusting the cam follower substantially tangentially and radially of the cam to thereby provide for adjusting cam timing and switch tripping.
