摘要： The invention concerns a microsystem capable of being used in a switching electrical appliance for switching an electric circuit between an open position and a closed position. More specifically, said microsystem comprises a part (1, 10, 100) mobile between two stable states, bearing at least one mobile contact (6, 60, 600) urged into contact, in one of the two stable states, with one or several stationary contacts (21; 22) of a stationary part to close the electric circuit. The invention is characterized in that a junction element (3a, 3b, 30a, 30b, 300) provides the junction between the mobile part (1, 10, 100) and the stationary part (2, 4, 40, 41, 400) and the junction element (3a, 3b, 30a, 30b, 300) applies mechanical stresses between the mobile part (1, 10, 100) and the stationary part to maintain the mobile part (1, 10, 100) in one of its two stable states.
