ABSTRACT:
A magnetic relay system is implemented to act as a relay driven by a magnetic flux yet capable of production through micromachining. The magnetic relay system has an electromagnet, a movable plate, and conductive contacts. The contacts are connected to the circuits of outside electrical systems that are to be controlled by the switching of the relay system. The plate is movable allowing it to engage both contacts and allow current flow between the contacts or to disengage both contacts and prevent current flow between the contacts. The electromagnet provides a sufficient magnetic flux at desired times to move the movable plate and thereby controls whether the movable plate is engaged with the contacts. The electromagnet, movable plate, and the conductive contacts may be formed on a substrate capable of construction using microfabrication techniques.
