Abstract

A switch assembly to provide snap action switching on a cam rise in a program timer includes a follower assembly on the free end of a first blade to engage the program member to reference the first blade relative to the program member. A cam follower for actuating a second blade has a relatively high coefficient of friction between it and the follower assembly so that when a steep cam rise is encountered the horizontal force from the cam rise forces the cam follower tightly against the follower assembly, to lock the cam follower to the follower assembly. At the end of the cam rise, the horizontal force is released and the snap action occurs.
