Abstract:
A disconnect switch. Oval receiving grooves (111, 121) are respectively provided at corresponding positions of a base (11) and an upper housing (12) of the disconnect switch. A protruding column (31) is separately provided on both sides of a movable contact carrier (3). The movable contact carrier (3) is movably disposed in the oval receiving grooves (111, 121) by means of the protruding columns (31). A spring (6) or/and a tension spring (7) is provided between the movable contact carrier (3) and the base (11). One end of the spring (6) or/and one end of the tension spring (7) acts on the base (11) and the other end acts on the movable contact carrier (3).
