A switch device is configured by engaging a plurality of switches in a cam section of an operating member in a manner such that a detecting section can detect positions of operation of the operating member based on electric ON/OFF states of the switches. With this arrangement, it is possible to detect the positions of operation of the operating member by only detecting the electric ON/OFF states of the switches wherever the position of operation the operating member may be. Consequently, a switch device that is simple in construction and capable of reliably detecting positions of operation of the operating member can be provided.

Switch device

A lever switch includes a common contact and a fixed contact both prepared on at least an inner bottom face, or any one of inner faces of walls surrounding the inner bottom face, and a movable contact which touches or leaves at least one of the common contact or the fixed contact when a lever rotates. Terminal sections of the common contact and the fixed contact extend through walls of the housing. This structure allows the lever switch to fix those terminal sections to a wired board, thereby preventing the lever switch from coming off from the wired board. As a result, the lever switch can work with reliability.

Lever switch

A slide switch is fabricated by having a coiled spring, which has coil-end seating portions at both ends totaling &#xbe; to 1 turn, contained in a case or an operating member such that the operating member is biased by the spring. By virtue of such a configuration, the spring is prevented from bulging out at its center portion or coming off the containing portion. Thus, a slide switch which can be fabricated easily while also saving manpower can be provided.
