<p>The switch comprises: a body (2) of electrically-insulating material, in which a cylindrical chamber (S) is formed, a plurality of fixed contacts (10 to 40) carried by the body (2) and extending into the chamber (3), with their surfaces flush with the internal lateral surface (3a) of the chamber (3), a further fixed contact (50) also carried by the body (2) and having a portion (50b) fixed to the base wall (3b) of the chamber (3), a rotor (5) rotatably mounted in the chamber (3), at least one movable contact member (7) fixed torsionally to the rotor (5) and having first and second portions (7b, 7a) facing the lateral wall (3a) of the chamber and the further fixed contact (50b) respectively, first resilient means (8) for thrusting the portion (7b) of the at least one movable contact (7) against the lateral wall (3a) of the chamber (3), and second resilient means (9) for keeping the second portion (7a) of the at least one movable contact (7) in permanent contact with the further fixed contact (50, 50b).</p> |
