The conventional slide switch described in Japanese Utility Model Publication No. Sho 57-10032 and Japanese Utility Model Publication No. 55-55469, including this conventional example, has a movable contact piece which is fixed. A spring for sliding and elastic contact with a spring, and a click action of a switch operation, that is, a click spring for giving a switching moderation feeling to a finger, are individually one each, a total of two coil springs and leaf spring contact pieces. Therefore, there is a problem that parts management and assemblability are significantly disadvantageous in comparison with a single spring having no switching moderation in terms of parts management and assemblability, leading to an increase in cost.

Further, apart from the above, Japanese Utility Model Application Laid-Open No. 63-137
No. 421, that is, a single leaf spring in which two pairs of opposite long and short ends of four end portions of a flat-shaped leaf spring material are used for a click and a movable contact piece for each pair. There is also a slide switch with a click made of material, but this switch has the disadvantage that it is prone to poor contact and moderation due to the “spring” inherent to the leaf spring. There was a problem that hinders the conversion.

An object of the present invention is to solve the above-mentioned problems. It is an object of the present invention to interpose a coil spring provided in a hole formed in a slider of a slide switch, and to have click projections on both sides thereof. By assembling the movable contact piece and the movable contact piece in series, one coil spring can be used both for clicking and for elastically contacting the movable contact piece to the fixed contact piece.
It is an object of the present invention to provide a slide switch which has a simple structure, improves workability, reduces cost, and provides a moderation of switching.
