Control switch relay and control circuit means

Abstract

A control switch has a switch shaft mounted for reciprocal rotational movement about its axis. A cam profile is fixed to the shaft and has first and second opposed cam surfaces. A driver is mounted to selectively engage the first or second cam surface to drive the switch shaft into a first clockwise position or a second counterclockwise position by remote actuation. The driver is connected to a rotary solenoid which allows uni-directional drive translated into two directional drive by the driver. A control circuit provides rapid actuation and slow release of the rotary solenoid along with operation of a linear solenoid when desired to select between first and second directional movement of the cam profile. The control circuit permits charging a capacitor while rapidly actuating a relay to actuate the rotary solenoid. A resistor provides for slow discharge of the capacitor to maintain the relay actuated over a slow release period after disruption of the charging circuit. A linear solenoid is interconnected with the charging circuit to enable selective actuation of the linear solenoid when desired to switch directional movement of the cam profile.
