An intermittent drive includes a pair of reciprocating drive pawls which individually and alternately drive a camstack in a step by step maneuver. Electrical switches open and close in response to the camstack. One of the drive pawls includes a lost motion connection between it and a rotating member. There is a sub-interval switch having a cam disposed within the intermittent drive and a cam follower which operates a switch.
