Coil Actuated Dual Detent

A coil-actuated dual detent is arranged such that the first detent is not removed from its detent position until the second detent is located in its detent position.

With reference to Fig. 1, interlock 11 is detented into cam 13, preventing rotation thereof. Collar 15 is free to rotate since armature 17 is free of the detent slot 19 thereof.

With reference to Fig. 2, armature 17 is driven against collar 15 upon energization of coil 21. Sufficient motion to induce the upward release of interlock 11 is provided only when armature 17 makes detent slot 19 of the collar
15.
