Abstract:
1. A micro-electro mechanical system switch, comprising: a fixed electrode formed on a substrate; a movable electric resistor formed on the substrate and having one end fixed to the substrate by a support portion of the movable electric resistor, the movable electric resistor and the fixed electric resistor being formed of a same layer, the moveable electrode resistor directly separating from and contacting the fixed electrode; a fixed electric resistor, formed on the substrate, having one end connected to the support portion of the movable electric resistor; and an output portion connected to the support portion of the movable electric resistor; when the movable electric resistor and the fixed electrode are set in a conductive state, a potential applied between the fixed electrode and another end of the fixed electric resistor being distributed according to a ratio of a resistance value of the fixed electric resistor and a resistance value from the one end to the other end of the movable electric resistor and being output to the output portion, and in a state when no voltage is applied, the movable electric resistor being parallel to the fixed electrode.
