Action of Magnetic Switches
|
Action One of the contacts in the glass capsule is made of a magnetic material; the other is non-magnetic. A nearby magnetic field from either an electromagnet or permanent magnet pulls one contact against the other, closing the switch. When you remove the magnetic field, the spring action in the stiff metal contacts opens the connection. Because the thin contacts have low mass, they can operate up to 10 times faster than conventional relays with similar ratings. |
