To provide a slide switch capable of making many operations with a small number of components and a simple structure.

A plurality of rod-shape projections are provided in a first component. A second component is combined with the first component in the direction along the radiation center line of the rod-shape projections of the first component. A plurality of slide auxiliary grooves corresponding to the plurality of rod-shape projections are formed in the second component so that the first component may be able to relatively slide-move respectively in each of the radiation projection direction of the plurality of rod-shape projections. A first electrode is installed respectively in each of the plurality of rod-shape projections and a second electrode which is electrically connected to the first electrode of the rod-shape projections is installed in each of the plurality of slide auxiliary grooves. The slide auxiliary grooves are formed in a shape in which at least two other rod-shape projections at the positions interposing the rod-shape member having slide movement direction in the radiation projection direction abut against the wall of the corresponding slide auxiliary grooves and stop slide movement when the first component slide-moves.
