MOTOR CONTROLLED SWITCH MECHANISM
摘要:
A motor and manual actuated switch includes a motor control circuit (12) for controlling the motor to rotate in either a clockwise or counterclockwise direction to actuate a mechanical switch (26) between the open circuit and short circuit states. The control circuit includes a capacitor (42) coupled in series with the motor winding (32) to form a series circuit and a control switch (24) for connecting a source of d.c. power across said series circuit when in a second position. Such a circuit allows for convenient use to most preinstalled two lead wiring facilities. When the control switch is moved to the first position, the capacitor charges, causing a current to flow through the motor winding during the charge time, thereby causing rotation in one direction. In the second position, the capacitor discharges through the windings, thereby causing opposite current flow and shaft rotation.
