ABSTRACT:
In a lever switch, a contact actuating part provided in a lever is movable in a first direction by shifting of the lever and the top portion of a movable contact is depressable in a second direction substantially at right angles to the first direction while being pressed by a pressing force caused by the movement of the contact actuating part. The lever switch includes a plate which is provided between the contact actuating part and the top portion of the movable contact to convey the pressing force to the movable contact. The top portion has a sloped face facing the contact actuating part so as to form an angle of friction .theta. 1 with respect to the first direction, the plate has a central part and a side part which is bent toward the contact actuating part so as to form an angle of friction .theta. 2 with respect to the first direction, and the angle of friction .theta. 2 is smaller than the angle of friction .theta. 1.
