    A micro electromechanical switchable capacitor is disclosed, comprising a substrate, a bottom elecrode, a dielaectric layer deposited on at least part of sai bottum electrode, a conductive floating electrode deposited on at least part of said dielectric layer, an armature positioned proximate to the floating electrode and a first actiuation area in order to stabilize the down state position of the armature. The device may futhermore comprise a second actuation area. The present invention provides shunt switches and series switches with actuation in zones attached to the floating electrode area of with relay actuation.
