CONTACTLESS SWITCH

The present disclosure relates to a non-contact switch. More particularly, the non-contact switch includes a button which is disposed at a predetermined position of a housing and operated by an external pressure while being formed, at one end portion thereof, with a magnetic substance; a magnetic field sensor device which is accommodated in the housing to face the magnetic substance and generates an induced voltage depending on an interval between the magnetic field sensor device and the magnetic substance; and a semiconductor device which is driven by the induced voltage generated at the magnetic field sensor device to switch power supplied from a separate battery to a separate load.
