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. When the pressing actuator is pressed by an operating knob so as to turn the drive body by a predetermined amount, a sliding actuator of the drive body slides on the conductive plate so as to turn the conductive plate. When the drive body is turned by another predetermined amount, the pressing actuator actuates a push-switch disposed near the casing.
