<p>A main body portion has fixed contacts and houses movable contacts. A lower electrode plate and upper electrode plate serving as the movable contacts are deformed at a time of a pressing operation. The upper electrode plate is contactable to the lower electrode plate and lower electrode plate brings contact pairs mounted in a center of the bottom inside the main body portion into conduction. On the bottom inside the main body portion, contacts serving as fixed contacts for a rotating operation are formed on the circumference of the same circle outside contact pairs for the pressing operation. A brush serving as the movable contacts is secured to a lever receiving rotating operational forces and brings contacts into conduction.</p> |
