Electrically controlled switch for high current switching operations with different configurations of fixed terminal contacts

A switch for high current switching operations, comprising:

• a switch body;
• a plurality of couple of moving contacts;
• a guide that drives the plurality of moving contacts between a contact position and a disconnected position to switch or interrupt current;
• a housing groove running perimetric in the switch body;
• at least one contact bar for connecting one of the moving contacts to a respective fixed terminal contact of the switch, the contact bar being hosted within at least a portion of the housing groove and having a free end projecting from the switch body to form the fixed terminal contact through a corresponding aperture of the switch body,
• wherein the at least one contact bar is configured to be changeable, at least during final assembly of the switch, to adapt the configuration of the fixed terminal contacts, and
• wherein the at least one contact bar is replaceable during final assembly of the switch only, in order to adapt the configuration of the fixed terminal contacts, wherein the switch body comprises different apertures corresponding to different configurations of the fixed terminal contacts.
