Abstract

A switch apparatus includes pushers (20, 21) for operating the switch bodies (17, 18), provided between an operating element (22), which is adapted to undergo a turning operation, and each of switch bodies. The pushers are configured in such a way as to be guided by pusher guides (15, 16) at places, each of which is located away from between a corresponding one of the switch bodies and a corresponding one of parts (24, 25) of the operating element for forcedly pushing the pushers. This eliminates the necessity for ensuring the necessary length (L11) of each of the pusher guides (15, 16), each of which is used for performing operations of forcedly pushing the switch bodies, between a corresponding one of the switch bodies and a corresponding one of the parts of the operating element for pushing the pushers.

Claims

1. A switch apparatus comprising:

an operating element pivotally supported through a pivotally supported portion thereof;

a pusher to be pushed by a pushing part of the operating element, the pushing part being disposed at a place shifted from the pivotally supported portion;

a switch body to be pushed by the pusher;

a guided portion away from a portion between the switch body and the pushing part, formed in the pusher; and

a pusher guide for guiding the guided portion in a linear direction, which is arranged at a place away from the portion between the switch body and the pushing part.

2. The switch apparatus according to claim 1, wherein the pusher includes the guided portion guided by the pusher guide and a main body portion which is pushed by the operating element and pushes the switch body.

3. The switch apparatus according to claim 2, wherein the main body portion is shorter than the guided portion in the linear direction.

4. The switch apparatus according to claim 3, wherein the main body portion is shorter than the pusher guide in the linear direction.

5. The switch apparatus according to claim 2, wherein the pusher includes an arm which is extended in a direction substantially perpendicular to the linear direction and connects the main body portion to the guided portion.
