A
forced-guided contacts relay has relay contacts that
are mechanically linked together, so that when the
relay coil is energized or de-energized, all of the
linked contacts move together. If one set of
contacts in the relay becomes immobilized, no other
contact of the same relay will be able to move. The
function of forced-guided contacts is to enable the
safety circuit to check the status of the relay.
Forced-guided contacts are also known as
"positive-guided contacts", "captive contacts",
"locked contacts", or "safety relays". |
