Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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, wherein the yoke driving mechanism includes an operational element provided in the switch element and configured to be able to move and engage with the yoke, and a biasing element configured to bias the operational element so as to separate from the yoke upon the yoke moving to the second position; wherein the biasing element is a slanted wall formed in the case. 2. The power generation switch according to claim 1 , wherein the operational element includes a roller disposed at a position at which the yoke and the operational element engage.
