ABSTRACT:
A slide switch 1 includes a movable contact 2 that has projections 11 formed thereon for preventing dislocation. The movable contact 2 is inserted together with a spring 8 into a holder 3. The holder 3 has regulating recesses 12, within which the projections 11 of the movable contact 2 can move only vertically. The holder 3 also has claws 9. The movable contact 2 has holes 10 that engage with the claws 9. A pole plate 4 has fixed contacts 5 fixed thereon, on which the movable contact 2 can slide with the holder 3 in compressive contact with the fixed contacts to switch the contact positions. At least one of the fixed contacts 5 is formed with a chamfer 15. Resin guide members 18 are fitted in the centers of slits 17 in the pole plate 4 for preventing the movable contact from falling into the slits. This structure prevents the movable contact of the slide switch from being dislocated when the contact positions of the slide switch are switched, and increases the durability of the slide switch.
