ABSTRACT:
A rotary cam actuated sequence switch assembly having a reversible electric drive for forward and reverse movement to selectively position the cam for actuating a plurality of switches in a desired sequence under electronic control of the motor. Reverse rotation of the cam causes a flip-over follower to lift the blade contacts of the switch controlling line power to the remaining switches thereby preventing the reverse rotation from causing damage to the device being controlled by the switches.
