Resistor Networks, digital potentiometers and microelectromechanical structures that include a plurality of resistors selectable by a plurality of microelectromechanical acquators are provided. More particularly, a thermal relay type of actuator is provided as a switch which may selectively control which of the plurality of resistors is connected. In one particularly advantageous embodiment, the heater for the thermal relay and the plurality of resistors are formed from a common layer of the integrated circuit structure, such as a doped polysilicon layer, which may simplify the manufacturing process. Preferably, a thermal arched beam acuator is utilized in combination with film resistors to provide an integrated circuit device suitable for applicaitons such as digital potentiometers.
