Abstract: A switching device includes three stationery contacts fixed to a casing and exposed on a bottom wall of casing, a conductive plate swingable about the central contact as a fulcrum and coming into contact with or detached from one of the other contacts, a drive body disposed on the conductive plate so as to be movable upwards and downwards and turnable about a shaft thereof, and a leaf spring elastically urging the shaft towards the bottom wall. The drive body has a pressing actuator protruding sidewards from the casing.

Accordingly, the portions to be pushed are slightly elevated when they are pushed by the manipulating knob.
