Abstract:
A switch operating mechanism for turning a switch on and/or off by pressing the switch, which is provided at a circuit board, the mechanism comprising:an operating knob, which has a front end and a back end and is rotatably supported by a spindle that is provided at a lower position than the switch; and a pusher having a base, a first pressing arm, and a second pressing arm, the first pressing arm and the second pressing arm extending parallel to each other from both ends of the base in a direction perpendicular to an axial direction of the base such that the pusher has a substantial U-shape when seen in side view, wherein the switch of the circuit board is disposed between the first and the second pressing arms of the pusher, the first pressing arm being positioned directly above the switch and able to press the same; the operating knob is disposed such that the front end thereof is disposed between the circuit board and the second pressing arm so that the front end is able to press the second pressing arm; and when the back end of the operating knob is moved upward, the front end thereof moves the second pressing arm of the pusher downward, whereby the pusher moves linearly along a direction perpendicular to the plane of the circuit board, and the first pressing arm of the pusher presses the switch to turn the switch on and/or off.
