EM switching unit with contact bounce prevention - has bridging compact mounted on elastic pad relative to armature supported on core with elastic mount

摘要

An electromagnetic switching device has a magnetic core (3) mounted on a fixed base (1) with a separating pad of elastic material (2). An armature element (4) supports a carrier (6) freely on a pad of elastic material (7) and has spring mounts to the fixed frame. A pin (5) passes through the armature and locates in elongated slots in the carrier. A spring loaded (8) bridging contact (9) is mounted on the carrier. Contact bounce is prevented by the energy absorbing action of the elastic material. ADVANTAGE - Maintains straight guidance path for contacts.
