Abstract
A manual and electric switch-on and switch-off conversion device used for a leakage protector comprises an upper fixed plate and a lower fixed plate. A rack plate is arranged in the gap between the upper fixed plate and the lower fixed plate. A contact is arranged at one end of the rack plate. A movable plate is hinged to the upper fixed plate through a fulcrum pin. A motor is arranged on the movable plate. An output gear of a motor shaft is arranged in the gap between the upper fixed plate and the lower fixed plate and is matched with a rack on the rack plate. A conversion rotating rod is arranged on one side of the upper fixed plate. A clutch mechanism is arranged on the conversion rotating rod and is provided with a manual station and an automatic station. The clutch mechanism drives the movable plate to swing around the fulcrum pin so as to make an output gear disengaged from or meshed with the rack on the rack plate. The manual and electric switch-on and switch-off conversion device is small in size, simple in structure and reasonable in design, time and labor are saved in the operation process, the electric operation and the manual operation are separated, and the problem that an existing electric switch-on and switch-off device can not be controlled through manual operation due to motor damage is solved.
