This contactless switching apparatus is comprised of a magnetic path having a U-shaped base of magnetic material, both ends whereof are made free, and a movable yoke which is put on one free end of the said base so that the inner end of the movable yoke can move inside both ends of the base, the said movable yoke being arranged so that the moving inner end of the said movable yoke may be opposite to the other free end of the said base to form a gap, either or both the movable yoke and one magnetic yoke of the base forming the said gap which are opposite to each other being made a bimetal yoke or bimetal yokes so that they bend in such a direction that the said gap may be narrowed when the base rises in temperature, a magneto-electric converting device being inserted in the said magnetic path so as to be actuated by the magnetic flux flowing in the magnetic path, and the converting device being connected to an external input power source and an external load.
