Abstract

A rocker switch device is provided in which a pair of shaft portions are projectingly provided on mutually opposing faces of extremity portions of a pair of side wall parts of a switch case, the pair of shaft portions being aligned on the same axis as each other, a bearing hole is formed in an operating knob so as to extend therethrough, the pair of shaft portions being rotatably fitted into the bearing hole, a projecting portion is provided on an outside face of the pair of side wall parts, the projecting portion being pressed into contact with the support body to thus prevent rattling of the switch case, and a support pin is fitted into the bearing hole, opposite ends of the support pin abutting against extremities of the pair of shaft portions respectively. Such arrangement prevents switch malfunctioning, and restrains deformation of the side wall parts.

First claim

The invention claimed is:

1. A rocker switch device comprising a switch case that retains a fixed contact and can be joined to a support body, and an operating knob that retains a movable contact and is axially supported on the switch case so that the operating knob can swing, the switch case having a pair of mutually opposing side wall parts with the operating knob sandwiched therebetween, and a linking wall part providing a connection between base portions of the pair of side wall parts,
wherein a pair of shaft portions are projectingly provided on mutually opposing faces of extremity portions of the pair of side wall parts, the pair of shaft portions being aligned on the same axis as each other, a bearing hole is formed in the operating knob so as to extend therethrough, the pair of shaft portions being rotatably fitted into the bearing hole, a projecting portion is provided on an outside face of at least one of the side wall parts, the projecting portion being pressed into contact with the support body to thus prevent rattling of the switch case, and the pair of shaft portions are formed so as to have a length such that mutually opposing extremities of the pair of shaft portions directly abut against each other.

2. The rocker switch device according to claim 1 , wherein the switch case is formed dividedly from a first case element having at least either one of the side wall parts and the linking wall part joined integrally to the base portion of said one side wall part, and a second case element having at least the other side wall part, the base portion of said other side wall part being latched on or fastened by a screw to the linking wall part.

3. A rocker switch device comprising a switch case that retains a fixed contact and can be joined to a support body, and an operating knob that retains a movable contact and is axially supported on the switch case so that the operating knob can swing, the switch case having a pair of mutually opposing side wall parts with the operating knob sandwiched therebetween, and a linking wall part providing a connection between base portions of the pair of side wall parts,
wherein a pair of shaft portions are projectingly provided on mutually opposing faces of extremity portions of the pair of side wall parts, the pair of shaft portions being aligned on the same axis as each other, a bearing hole is formed in the operating knob so as to extend therethrough, the pair of shaft portions being rotatably fitted into the bearing hole, a projecting portion is provided on an outside face of at least one of the side wall parts, the projecting portion being pressed into contact with the support body to thus prevent rattling of the switch case, and a support pin is fitted into the bearing hole, opposite ends of the support pin abutting against extremities of the pair of shaft portions respectively.

4. The rocker switch device according to claim 3 , wherein the switch case is formed dividedly from a first case element having at least either one of the side wall parts and the linking wall part joined integrally to the base portion of said one side wall part, and a second case element having at least the other side wall part, the base portion of said other side wall part being latched on or fastened by a screw to the linking wall part.
