Claims

[Scope of utility model registration request]

An iron piece formed in a "U" shape, and a magnetic core arranged approximately in the center of the opposing spacing between both side surfaces of the iron piece, with its lower end abutting the inner bottom surface of the iron piece;
A coil wound around this magnetic core is arranged such that, in its first moving position, one of its magnetic pole parts is in contact with the upper end of the magnetic core, and the other magnetic pole part is in contact with the upper end of one side of the iron piece. and a magnet disposed with the other of the magnetic pole parts in contact with the upper end of the magnetic core and one of the magnetic pole parts in contact with the upper end of the other side of the iron piece in the second moving position. Power generation switch.
