Abstract

A power relay for a vehicle has a housing and two connecting bolts that are introduced into the housing so as to contact a load current circuit. The power relay further having a coil assembly that is arranged in the housing, the coil assembly contains a magnetic coil and a magnetic armature that is coupled by way of a force-transferring member to a contact bridge that can be moved in a reversible manner between a closed position and an opened position and can be displaced in the housing under the effect of a magnetic field that is generated by the magnetic coil. The contact bridge supports two contact elements that together with the mating contacts of the connecting pin form a first contact pair and a second contact pair. The contact pairs form a three point bearing arrangement in the closed position.
