ABSTRACT:
The control switch according to the present invention provides different electric conduction states and may be used for setting a point indicated by a cursor on a monitor in a navigation system. The control switch comprises (i) two terminal members each having four terminals, and (ii) common terminals respectively corresponding to the two terminal members. One terminal member is different in phase from the other terminal member. When one common terminal and its terminal member are short-circuited by a movable contact-piece member, the other common terminal and its terminal member are in a non-conduction state. When the common terminal and its terminal member are short-circuited by a movable contact-piece member, the one common terminal and its terminal member are in a state of non-conduction.
