ABSTRACT:
A motorized drawer is moved from a fully closed to a fully open position, or vice versa, in response to user activation of a single pole double throw switch. The motor moving the drawer is connected to the user activated control switch and to a limit switch. Whenever the drawer reaches one of the end positions, a limit switch opens the circuit through which the motor was energized to move the drawer to that position. At the same time, the limit switch partially completes the circuit for energizing the motor in the opposite direction. The latter circuit is completed when the user again activates the control switch, i.e. completes the circuit allowing current flow through the motor in the direction required to drive the drawer to the other end.
