SWITCH OPERATING DEVICE

PROBLEM TO BE SOLVED: To provide a switch operating device which has a compact size with less parts and can be assembled at low cost and easily. SOLUTION: In this switch operating device, a motor 1 rotates an operation shaft 4 through a reduction gear train 2, a force of a spring 12 is accumulated through a crank arm 6 secured to the operation shaft 4 by a rotation of the operation shaft 4, an operation cam 15 mounted to the operation shaft 4 is rotated by the rotation of operation shaft 4 according to the accumulated force of the spring 12, and then contacts of the switch is operated through a link mechanism by the rotation of the operation cam 15. A rotation center of a final gear 3 in the reduction gear train 2 is disposed on an axial of the operation shaft 4, and a recess 26 is formed at side surface of the final gear 3 in the range of semi circumference thereof, circumferentially. A pin shaped projection 27 formed at side surface the operation cam 15 is inserted into the recess 26. An end of the recess 26 presses the projection 27 to accumulate the force of the spring 12 by the rotation of final gear 3 according to the motor 1, and the recess 26 is run idle by the projection 27 by the rotation of the operation shaft 4 according to the force of the spring 12.
