ABSTRACT:
A vehicle switch is capable of properly switching on/off electrical connection between fixed contacts. The fixed contacts of the switch are oppositely disposed on a substrate so as to be parallel to a moving direction of a moveable piece. A barrier constituted by a dent or a projection is disposed between the fixed contacts to increase the creeping distance between the fixed contacts. With such a simple structure, the vehicle switch can suppress degradation of insulation characteristics between the fixed contacts, whereby the electrical connections between the fixed contacts are properly established or cut-off.
