<P>PROBLEM TO BE SOLVED: To devise an operation mechanism unit for switch, fitted to an opening/closing part unit having position relation of electrodes and an angle of rotation of a movable electrode restricted, so that the movable electrode is disabled to rotate with its own weight. <P>SOLUTION: A projection 70 is projected from a surface of a lever 11a perpendicularly to the surface. A projection 80 is projected from a surface of a side face 52 of a pedestal 50 perpendicularly to the surface. A compression spring 90 for control has one end supported by the projection 70 and the other end supported by the projection 80. The projection 70 is united with the lever 11a, and then rotates on the axis of rotation of a main shaft 10 to draw an arcuate track 71. The projection 80 is united with the pedestal 50, and then always at a stop irrelevantly to rotational operation of the main shaft 10 and a handle shaft 20. A movable electrode 220 never rotates with its own weight by elastic force of a compression spring 90 for control which is compressed as the projection 70 rotates. <P>COPYRIGHT: (C)2013,JPO&INPIT |
