INHIBITER SWITCH
In an inhibiter switch, a detent plate may be rotated on one side around a rotational shaft to be assembled in a pole board, and a stopper may be provided in the pole board to define a rotation range of the detent plate on the one side. An interference portion may be provided on a movement track of a movable contact piece when the detent plate rotates around the rotational shaft, wherein the interference portion may interfere with the movable contact piece to become resistance to rotation of the detent plate to the other side around the rotational shaft.

Control apparatus for lifting mechanism
A control apparatus for a lifting mechanism, including: a mount box, a circuit board, and a toggle assembly, the circuit board including a lift switch which is elastically auto-reset and configured to control lifting, the toggle assembly being operable by pushing to close the lift switch. a limit portion is provided on each of two sidewalls of the toggle assembly, the limit portion being staggered with the lift switch along a depth direction of the toggle assembly and vertically movable with the toggle assembly; and a stop portion is provided on each of two sidewalls of the mount box; the toggle assembly includes a free state in which the stop portion vertically stops the limit portion and a pushed state in which the toggle assembly rotates about a pivot point which is a contact point between the stop portion and the limit portion.
