Реферат: The moving contacts (5, 7) arranged at opposite ends of a bridge (8) cooperate with fixed contacts (4, 6). The bridge is moved at right angles to its plane by an electromagnet (10) with a stationary yoke (11), a coil (12) and an armature (13) which is coupled to the bridge by a spring stirrup (16). The vibration damper (20) is a wire mesh esp. of stainless steel which impedes the bridge movement by its compression when the spring (17) moves during the electrical and mechanical contact time of about half a microsecond. Additional contact force is generated for up to 1 microsecond. USE/ADVANTAGE - In l.v. appts. for remote switching of electrical loads, duration of contact bounce is limited and arcing and burning of contacts are reduced.
