Abstract
An electromagnetic relay for use in a high-frequency circuit includes an armature 3 mounted on a central shaft 16 for pivotal movement between two switching positions. A total of four actuator cards 5 are disposed on two opposite sides of the armature 3, each card carrying a contact spring 8. Each contact spring serves to bridge a pair of fixed contacts 6, 7. The contact springs and fixed contacts are located in shield casings 9 disposed on both sides of the armature 3. Return springs 19 urge the cards 5 into abutment with the respective sides of the armature 3. Sufficient electrical separation as required for high-frequency applications is achieved between the two contact systems due to the intermediate disposition of the armature 3. The provision of an individual actuator card 5 for each contact spring 8 permits independent adjustment of each contact.
