ABSTRACT:
A slide switch device adapted to be immersed in automatic transmission oil or the like. A printed circuit board 1 is provided with fixed contacts 11. A guide rail 19 is formed extending in a sectional T-shaped form from a side surface of the printed circuit board 1. A movable board 3 has a movable contact 2 and a pin 5 press-fitted therein. An operating member 4 has an elongate hole 42 for receiving the pin 5, a retaining portion 44 for a slide member 6, and a coupling portion 47 for coupling to a manual valve 9 of an automatic transmission. The retaining portion 44 is formed with a cut-out 45 extending from one side thereof to have an open edge. At the open edge is formed a crimp piece 46 through a connecting portion 49 of a reduced section for retaining the slide member 6. The slide member 6 has a slide portion 61 in a channel form for being fitted on the guide rail 19 of the printed circuit board 1, band a groove portion 63 formed between the slide portion 61 and a head portion 62 for being fitted to the cut-out 45 of the operating member 4. A frame body 7 has an open hole 72 formed in a lower portion 71 to a size sufficient for slidably receiving the pin 5 and freely passing liquid therethrough, and a crimp piece 74 formed in a side portion. The open hole 72 has opposite edges formed by downwardly slanted surfaces 73 for allowing the oil intruded within the frame body 7 to flow out.
