Abstract:
An electromagnetic relay includes: a base; a pair of fixed contact terminals, each including a fixed contact and a first fulcrum fixed to the base; a movable contact spring including a pair of movable pieces, each of the movable pieces including a movable contact contacting and separating from the fixed contact; an armature that is coupled with the movable contact spring, by a rotary motion around a second fulcrum; an electromagnetic device that drives the armature; and a permanent magnet arranged between the pair of fixed contact terminals and between the pair of movable pieces to generate a magnetic field. The first fulcrum and the second fulcrum are arranged mutually in opposite directions with respect to the movable contact or the fixed contact.
