Abstract
An microelectromechanical switch uses electrostatic attraction to draw a beam toward a contact and electromagnetic repulsion to disengage and repel the beam from the contact. The electrostatic attraction is generated by a gate electrode. The electromagnetic repulsion is generated between the beam and a magnetic coil positioned on the same side of the beam as the contact. The magnetic coil produces a magnetic field, which induces a current in the beam that repels the magnetic coil. The gate electrode and the magnetic coil may be co-planar or in different planes. A circuit may also operate a coil-shaped structure act as the gate electrode and the magnetic coil, depending on the configuration.
