<p>An electromagnetic relay 10 includes an auxiliary yoke 17 extending along an upstanding portion 27 of a primary yoke 14 and magnetically connected to the upstanding portion 27 through a magnetic connection portion 41, a permanent magnet 18 arranged between the upstanding portion 27 of the primary yoke 14 and the auxiliary yoke 17 and a magnetic saturation portion 21 provided in the upstanding portion 27. The electromagnetic relay 10 is designed to allow the magnetic flux of the permanent magnet 18 to flow through the upstanding portion 27, an operation piece 15, the magnetic connection portion 41 and the auxiliary yoke 17 when a second attracted portion 32 is spaced apart from one end portion of an iron core 12 with the conductive coil 24 kept not excited, and to flow through the upstanding portion 27, the operation piece 15, the iron core 12, a base end portion 26, the magnetic connection portion 41 and the auxiliary yoke 17 when the second attracted portion 32 is attracted to the end portion of the iron core 12 with the conductive coil 24 kept not excited.</p> |
