Abstract
A multi-functional polarity-correcting plugging-coupling switching device includes a rotary component, which is rotatable and has at least one inspection element that is electrically connected to a touch control resistor and a live connection of a power plug. With a user using a hand to touch the touch control resistor, a closed circuit is formed with the human body for identifying correct position of polarization of the power plug. Further, through rotation of the rotary component, correct polarization and voltage level can be selected. Further, a resistive indicator is provided for indicating correct connection of earth line.
Claims19
A multi-functional polarity-correcting plugging-coupling switching device comprising:
- an insulation enclosure, which has a first end to which a polarization-dependent conductive pin set is mounted and an opposite second end forming an opening;
- a rotary component received in the insulation enclosure and rotatable, in a limited manner, along a circumferential surface of the opening, the rotary component forming a plurality of terminal compartments electrically connectable to the conductive pin set;
- and
- at least one inspection element mounted at a predetermined location on the switching device, the inspection element being in electrical connection with a touch control detection element and a transmission member.
