Abstract
A power generation switch comprising: a case; a core, a coil being wound around the core; a magnet magnetically connected with the core; a yoke in which the magnet is disposed; an elastic element that supports the yoke and elastically deforms so as to deviate a position of the magnet from the core; a switch element that is operated to be moved; and a yoke driving mechanism that moves the yoke so that upon an engagement of the switch element and the yoke being released, the yoke moves between a first position and a second position due to elastic force of the elastic element, wherein first magnetic flux is generated by the core and the magnet when the yoke is at the first position and second magnetic flux different from the first magnetic flux is generated by the core and the magnet when the yoke is at the second position.
