Switch operating mechanism

摘要

In a switch operating mechanism, a switch of a circuit board is disposed between a first pressing arm and a second pressing arm of a pusher having a substantial U-shape when seen in side view, and the first pressing arm is positioned directly above the switch. A front end of an operating knob is disposed between the circuit board and the second pressing arm. When the operator moves the operating knob upward, the front end of the operating knob moves the second pressing arm of the pusher downward. Thus the pusher moves straight along the direction perpendicular to the plane of the circuit board, and the first pressing arm of the pusher presses and activates the switch.
