摘要

A relay having a coil body 1 with a tongue-shaped armature mounted on the inside of the coil body and the armature is secured at one end 6a to a first coil flange 4 and its free end moveable between two pole plates 8 which are in the vicinity of the second coil flange 5. At the end where the armature 6 is fastened the coil flange 4 comprises a rim bead which together with the retaining webs 21 of the armature 6 form a planar seating surface for a sealing film 12 and at the other end of the coil flange 5 the two pole plates 8 together with spacing members of the coil body form a planar seating surface for a sealing film 9 and a good seal of the relay is obtained due to such simple structure while maintaining good magnetic coupling.
