Device for connecting two points in an electrical circuit. The device acts externally like an individual relay, but includes a first micro electro-mechanical systems ("MEMS") relay and at least a second MEMS relay. Each relay has four condenser plates and a conducting element movably housed inside the relay, opening and closing a circuit, by applying certain control signals to the condenser plates. The second relay can be connected to one of the plates of the first relay, to create a high impedance in the plate, or it can be connected serially or in parallel to the first relay but controlled with different control signals, whereby the operational range of the first relay and, therefore, that of the overall device, is extended.
