Abstract

A power relay for a vehicle is disclosed. The power relay has a housing formed by a connector base and a housing can set thereon, two connection bolts being inserted into the connector base for contacting a load circuit. The power relay further has a coil subassembly arranged in the housing and containing a solenoid coil and an armature. The armature is coupled by a force-transmission member to a contact bridge and can shift in the housing, under the effect of a magnetic field generated by the solenoid coil, in such a way that the contact bridge can be reversibly moved between a closing position, in which the contact bridge bridges the connection bolts in an electro conducting manner, and an opening position, in which the contact bridge is not in contact with the connection bolts. The housing can is configured as an injection-molded component made of plastic.
