Abstract
A microelectromechanical device is provided which includes a beam configured to apply an opening force on a closed switch. The opening force may be substantially independent of a force stored in the closed switch. A combination of the force applied by the beam and the force stored in the closed switch may be sufficient to open the switch after removal of a force associated with actuation of the switch. Another microelectromechanical device includes a switch beam spaced above a closing gate and a contact structure. The device may also include an additional beam configured to apply a force on the switch beam in a direction away from the contact structure. A method for opening a switch includes reducing an attractive force between a switch beam and a closing gate. The method also includes externally applying a mechanical force on the switch beam in a direction away from the closing gate.
