The present switch has a main switch lever so pivoted in the trough of an insulating housing, that the lever plays in a path, slightly deviating from the troughway. This assures contact pressure between the conducting lever and fixed contacts along the troughway. A conducting gate switch lever is designed for making and breaking the feeding connection between an electrical source and the main lever. With the gate lever "off", the main lever may pass along a row of fixed contacts without any effect, until the selected contact is reached. Then, the gate lever may be energized by making connection with the source; thus a piece of equipment is fed over the selected fixed contact. The present switch safely handles, unlike a rotating switch, ionized gases, because these gases do not drift by several contacts on their way out. No unwanted electrical bridging to other than the selected pieces of equipment will occur. The selector switch may be used for interconnection of telephones, as a translator aid, or for selective command of machine tools in automated production processes.
