ABSTRACT:
A switching system for a solenoid reciprocator motor of a type which has a piston arranged to reciprocate into and out of a solenoid. The switch is an SCR rectifier and the trigger lead to close the switch is pulsed by a commutator operating in unison with the movement of the solenoid or a shaft rotated by the solenoid. The energizing cycle when the SCR switch is closed is terminated by a disconnect lead which is pulsed responsive to a subsequent contact of the circuit by the commutator. A preferred mode of pulsing the disconnect circuit is to associate the disconnect circuit with another solenoid of the motor whereby the first solenoid is turned off when the other solenoid is turned on by the commutator.
