ABSTRACT:
A switching device having a central actuator and two outer actuators disposed separately from the central actuator on two sides, wherein the central actuator is a cylindrical dial (23) supported rotatably and depressibly by a pair of spindle bearings (26) included in a base plate; the base plate (25) supporting the dial (23) is fitted in a frame; the outer actuators are pivotable in a direction approximately perpendicular to a direction in which the three actuators are arrayed and about a pivot approximately perpendicular to a direction in which operating surfaces of the outer acutators are pushed to press a contact (30) disposed on the frame; and each of the outer actuators has a to-be-supported piece (34) extending to a position where the outer actuator deviates from a lateral edge of the dial (23) in the rotating direction as viewed from the front. The outer actuator is pivotally attached at the end of the to-be-supported piece (34) to the frame (22) and has a center axis crossing the pair of spindle bearings of the central actuator.
