A multi-pole switch assembly includes a housing, a plurality of switches, and an actuator. The switches are disposed within the housing, and each switch is coupled to receive an actuation force and is configured, upon receipt of the actuation force, to move between a first position and a second position. The actuator is disposed at least partially within the housing and is configured to at least substantially simultaneously engage, and thereby supply the actuation force to, each switch to thereby move all of the switches, with substantial simultaneity, to either the first or the second position. The actuator is rotatable to a plurality of set rotational positions to thereby vary the substantial simultaneity.

Economizing contact includes a fixed part, a part movable along a main direction, between a contact position and a break position, and an elastic blade attached to the fixed part forms an electric contact, as well as a stop mounted on the movable part and arranged for being away from the blade and coming to bear on the blade when the movable part is in contact position. The fixed part defines an orifice for passage of the stop facing the blade, where the orifice has an inner section substantially identical to an outer section of the stop, where the stop is movably mounted in translation in a plane on the movable part.
