ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a slide switch.
2. Related Art
In a conventional slide switch, a case b in which a contact holder a is received slidably, and a case upper cover d provided with an operation knob c so that the operation knob c can be operated to slide are formed separately from each other as shown in FIG.

. In addition, a fitting chamber g for a spacer f which closes a connecting long hole e formed in the case b is defined by the case b and the case upper cover d. The spacer f is an indispensable part for water proof by operation.
However, in the above-mentioned conventional slide switch, there is such a problem that, since the fitting chamber g for the spacer f is formed by the case b and the case upper cover d, looseness occurs between the fitting chamber g and the spacer f if the dimensional accuracies of both parts are not ensured so that it becomes difficult to make a sliding operation of the spacer f smooth and it becomes difficult to ensure water resistant operation.
The present invention is intended to solve the foregoing problem, and it is an object thereof to provide a slide switch in which the dimensional accuracy of a fitting chamber is ensured to make a sliding operation of a spacer smooth and to ensure water resistant operation.
SUMMARY OF THE INVENTION
In order to relieve the above problem, according to the present invention, there is provided a contact holder received slidably, and a fitting chamber for a spacer which closes a connecting long hole formed in said case molded integrally, a slide operation surface of an operation knob formed on the outer surface of said fitting chamber, and a connection shaft portion formed on said operation knob inserted into said spacer through a sliding long hole formed in said slide operation surface and said connection shaft portion wherein said contact holder are connected to each other by means of a connection pin inserted into said connecting long hole.
According to the above-mentioned slide switch, the fitting chamber for the spacer is molded integrally with the case which receives the contact holder slidably. Accordingly, it is possible to ensure the dimensional accuracy of the fitting chamber, and it is possible to realize a smooth sliding operation of the spacer and maintain a water resistant seal about the connection pin. In addition, the connection shaft portion of the operation knob inserted into the spacer through the sliding long hole formed in the slide operation surface is connected to the contact holder through the connection pin inserted into the connecting long hole formed in the case. Accordingly, a smooth sliding operation of the spacer is ensured, so that there is such an effect that it is also possible to improve a sense of operation of the operation knob.
