FIELD: low-voltage switching apparatuses; on-load and no-load connection and disconnection of electric circuits. ^ SUBSTANCE: proposed ON/OFF and disconnecting switch has case with fixed contacts installed in its recess, slider with movable contacts, cover attached to case, arc-control chamber, and ON/OFF mechanism incorporating grip, shaft, hub rigidly fixed to shaft and installed in clamp which is attached on side of switch case. Hub-carrying shaft is coupled on one end with grip and on other end, with lever disposed on rear side of case in its recess and coupled through link with slider pin end. Recess mounts extension spring attached on one end to slider pin end and on other end, to clamp. ^ EFFECT: reduced number of parts and material input, provision for instant disconnection and simultaneous switching of circuit in poles. ^ 1 cl, 3 dwg |
