Abstract
An electromagnetic relay constructed as a hinged-armature relay in which an armature (5) is attached to a flat-shaped spring (6) which spring is constructed as one piece to serve both as a switch-contact spring and as a return spring and which is mechanically and electrically coupled to a load-current terminal (11), with the load-current terminal having a spring affixing area (11a) and a terminal area (11b), wherein the spring affixing area and the terminal area of the load-current terminal are bendable relative to one another. A response voltage of such a relay can be adjusted in a particularly uncomplicated and quick manner using a wedge-shaped adjusting tool (12) to bend the affixing area relative to the terminal area.
