- a rotatable cam-carrying member having cam surfaces thereon;
- a timing motor having a rotor that rotates in response to electrical stimulation;
- a drive mechanism for causing rotation of said rotatable cam-carrying member in response to rotation of said rotor;
- a plurality of cam-actuated switches, each cam-actuated switch mounted for engagement to a cam surface of said rotatable cam-carrying member for actuation of said cam-actuated switch in response to rotation of said rotatable member, and making and breaking an electrical connection in response to actuation by said rotatable member;
- and
