Claims

[Scope of utility model registration request]

An electric operating device that rotates a crank by moving a drive pin fitted with a guide groove of a fixed plate along the guide groove, and causes an operating piece to perform closing and opening operations via the crank. In the limit switch of
A movable plate capable of reciprocating in one direction is arranged parallel to the fixed plate at a position overlapping with the fixed plate, and the crank is linked to the reciprocating movement of the movable plate, and the movable plate controls the movement of the drive pin. A limiting square hole is provided so that when the driving pin moves to the vicinity of either end of the guide groove, the driving pin contacts an edge of the square hole and moves the moving plate. A limit switch for an electric operating device, characterized in that the crank is interlocked with the movement of the movable plate to perform closing and opening operations.
