<p>A main body portion (10) has fixed contacts and houses movable contacts (30, 40, 60). A lower and upper electrode plates (30,40) serving as the movable contacts are deformed at a time of a pressing operation. The upper plate (40) is contactable to the lower plate (30) and the lower plate (30) brings contact pairs (16, 17) mounted in a center of the bottom inside the main body portion (10) into conduction. On the bottom inside the main body portion (10), contacts (65) serving as fixed contacts for a rotating operation are formed on the circumference of a same circle outside contact pairs (16, 17). A brush (60) serving as movable contacts is secured to a lever (70) receiving rotating operational forces and brings contacts (65) into conduction.</p> |
