Title:
MAGNETOELECTRIC HIGH-SPEED CHANGE-OVER SWITCH WITHOUT POWER WASTE
Document Type and Number:
WIPO Patent Application WO/2007/041959
Kind Code:
A1
Abstract:
A magnetoelectric high-speed change-over switch without power waste, comprising the
first electromagnet which includes a core, windings and contacts. The switch also
comprises the second electromagnet, and a permanent magnet is provided between
the electromagnets. The permanent magnet includes contacts which correspond to
the contacts of the first electromagnet. The windings of the electromagnets are
in series or parallel connection. The switch employs the combination of the principles
of electromagnetic induction and magnetics, and realizes open or close rapidly.
Generally, the state of open or close is sustained without current, or the switch
can work without current. So the contacts can not destroy.
