A Kabuki device to positionally maintain and release a stage setting responsive to electric current from a power source. A box-like body, defining a medial chamber with a slot communicating therewith, carries a solenoid in the chamber. A movable solenoid arm communicates with a spring biased lever arm that pivots on an offset axle to provide mechanical advantage to one end of the solenoid arm. One metal ring interconnected to the stage setting is inserted through the slot and is positionally maintained by a ring support pin carried by the pivoting lever arm. A finger hole defined in one end of the body allows manual manipulation of the lever arm for resetting. Jumper cables having plural electrical leads allow a plurality of devices to be interconnected in series in multiple predetermined groupings.
