Abstract: In order to prevent resin around fixed contacts from being carbonized by an arc produced when a movable contact plate is brought into contact with the fixed contacts and separated therefrom, a sliding switch comprises a terminal plate provided with two fixed contact plates and a movable plate provided with a movable contact plate, which is brought into contact with the fixed contact plates. Each of the fixed contact plates has a fixed contact protruding from the terminal plate. The movable contact plate includes at least a pair of protrusions on both sides thereof.

Abstract: A movable member 4 is slidably mounted within a space 3 formed by a first fix member 1 and a second fix member 2 composing a case. The movable member 4 is made of a white type resin, such as polyacetal, and composed of a column-shaped extended section 4a extending frontwardly for being pulled from and inserted into the space 3, a bottom wall 4h and side walls 4d, 4d extending from the extended a section 4a rearwardly, and a rear wall 4p coupled with the bottom wall 4h and the side walls 4d, 4d. The extended section 4a is fixed with a knob 5. The second fix member 2 forms a lamp base 2c loading light sources 9 and 10. A displaying section 5b, such as a display mark and characters, is provided on the knob 5, and a displaying member 15 made of a transparent resin with white color, such as a heat-resistance acrylic, is embedded in the displaying section 5b at the back surface of the knob 5.

Abstract: A push lock switch having a lock mechanism for use as a hazard switch or a rear defogger switch on an instrument panel of an automobile. The switch has first and second stationary members assembled together which define a space into which a movable member is slidably fitted. A push button fits over the movable member. A coil spring is mounted between the movable member and the first stationary member. The coil spring has first and second compression parts in a one piece construction with each other and urges the movable member toward the push button. A movable contacting strap is fixed to the movable member. The movable contacting member includes movable contacts and a retainer. The movable contacts slide into or out of contact with fixed contacts on the second stationary member when the movable member is pushed by the push button. The first stationary member has a bottom wall in which a recess is formed and on which a plurality of ribs are formed on the recess.
