Abstract
The present invention is directed to a latch that includes a housing, a pawl pivotally supported by the housing and movable between a latched position and an unlatched position, a spring biasing the pawl toward the unlatched position, and a locking member being rotationally movable about an axis of rotation between an open position and a locked position. The locking member interferes with the movement of the pawl such that the pawl is maintained in the latched position when the pawl is in the latched position and the locking member is in the locked position. The locking member allows the pawl to move to the unlatched position when the locking member is in the open position. The latch may further include a motor housing, a lockplug, a lockplug member, at least one roller switch, at least one gearbox, and a motor.
