ABSTRACT:
A two-stage movement seesaw switch apparatus of the light irradiation type which is compact and superior in operation feeling. The two-stage movement seesaw switch includes a pair of operation plates disposed immediately below a manually operable knob. Two sets of push switches, each set including two push switches, are disposed such that a straight line interconnecting the push switches of each set extends obliquely with respect to a center axis of pivotal motion of the manually operable knob. The push switches are actuated by contact with the operation plates when the manually actuated knob is pivoted. Each of the operation plates has an opening formed therein for passing light emitted from an LED therethrough and has a pair of projections formed thereon next to the opening.
