Abstract
A small-sized electromagnetic relay which can afford high current and dissipate generated heat efficiently is disclosed. A plate section for coupling to one side of a yoke is formed on a movable contact terminal . Countersunk rivet features at three or more positions which are not aligned on a line on the plate section couple the movable contact terminal to the yoke . A base end of a movable contact spring is coupled to the surface of the plate section opposite to the yoke to support the movable contact spring . In the countersunk rivet feature, each protrusion formed on the yoke is inserted into the corresponding countersunk hole formed on the plate section , respectively, and the tops of the protrusions are crushed to expand its diameter so as to sandwich the plate section against the yoke
