ABSTRACT:
An electromagnetic relay comprises a base member, an electromagnet system including a coil, a core and an armature, and a contact arrangement anchored in the base member and having at least one movable contact spring that is switched by a rod-shaped actuation element. The contact location and the attack point of the actuation element at the contact spring are offset relative to one another such that they lie a distance from one another in a projection onto the bottom surface of the base member so that the attach point and the contact location are prevented from lying above one another in all assembled attitudes that come into consideration and so that abraded material of the actuation element cannot fall onto the contact location and contaminate the contact surfaces.
