Patent ID: 7560656

Claim:
A switch, comprising: a switch base; a stationary contact fixed to the switch base; a control knob attached to the switch base so as to be movable between a first operating position and a second operating position; a movable contact holder which is movable in association with the movement of the control knob to the first and second operation positions; and a movable contact which is formed separately from and supported by the movable contact holder and comes into and out of contact with the stationary contact in response to the movement of the movable contact holder, the movable contact comprising an L-shaped positioning part at a first end and a U-shaped contact part at a second end opposite the first end, the L-shaped positioning part abutting an end of the movable contact holder, wherein the control knob is supported on the switch base via a first pivotal shaft so as to be tiltable between the first and second operating positions; wherein the movable contact holder holds the movable contact, faces an inner side face of the control knob, and is supported on the switch base, via a second pivotal shaft substantially parallel with and apart from the first pivotal shaft, so as to tilt between a first and second actuation positions; wherein the movable contact holder is provided with a sliding surface which faces the control knob; wherein a control plunger whose tip end slidably abuts on the sliding surface is fitted to the control knob so as to be slidable in a direction perpendicular to an axis of the first pivotal shaft; wherein the control plunger is urged by a spring in a direction to abut on the sliding surface; and wherein the movable contact is attached to the movable contact holder so that the U-shaped contact part contacts the stationary contact when the movable contact holder is turned to at least one of the first and second actuation positions.
