Patent ID: 7420448

Claim:
An electromagnetic relay comprising: an electromagnetic driving block composed by a coil, an iron core, a yoke, and an armature; first, second, and third terminals fixed to a base; fixed contacts provided at positions that generally form a triangle on an upper surface of the base; a first movable plate having movable contacts provided at positions corresponding to two of the three fixed contacts, respectively, the first movable plate provided to coincide with a line that connects the two fixed contacts; and a movable contact corresponding to the other fixed contact, and provided in a central portion of a second movable plate parallel to the first movable plate, wherein the first movable plate and the second movable plate are fixed to a pressing plate exhibiting a conductive property and a spring property, the first movable plate and the second movable plate are attached to a movable spring having both ends supported by the base so that center lines of the movable plates coincide with a center line of the movable spring, and the armature drives the pressing plate depending on whether or not a current is carried to the coil, thereby opening or closing a contact circuit, whereby the pressing plate generates inward flexions in the movable spring and a wipe operation is carried out with respect to the fixed contacts and the movable contacts.
