Abstract:
An electromagnetic relay comprising a coil constituting an electromagnet, an iron core, a yoke, a, movable iron member attracted by an electromagnet, a movable contact spring to return said movable iron member to its initial position, a movable contact coupled to said movable iron member, a stationary contact disposed opposite to said movable contact, a stationary contact terminal conductively coupled to said stationary contact to lead to the outside, and a movable contact terminal conductively coupled to said movable contact to lead to outside, wherein said movable contact opens/shuts relative to said stationary contact by means of the attractive force of the electromagnet and the resilient action of said movable contact spring, so as to change the conductive state between said movable contact terminal and said stationary contact terminal, characterized in that:a plate section which is coupled to at least one side of said yoke is formed in said movable contact terminal, said movable contact terminal being coupled to said yoke at one or more particular point(s) of said plate section by countersunk rivet feature(s); said movable contact spring is coupled to the surface on said plate section opposite to said yoke; and said countersunk rivet feature is formed by inserting a protrusion formed on said yoke into a countersunk hole formed on said plate section, and crushing the top of said protrusion increase its diameter so as to sandwich said plate section against said yoke.
