The centrifugal disconnector is used to automatically switch the triggering phase of single-phase asynchronous motors. It provides improved switching due to easier extinguishing the voltaic arc. The centrifugal disconnector connects a coaxially positioned base (1) and disk (2) and according to the utility model to the upper side of the base (1), a flat spring (6) is fixed, shaped as an ellipse with round opening in its centre, and in the ends of the larger axis, two contact bumps (4) are riveted, and symmetrically against the small axis of the ellipse in the flat spring (6) arched cut-outs (12) are formed, where towards the large axis and adjacent to the contact bumps (4) two barrel-shaped springs (8) are mounted, opposite to each other. To base (1), two contact terminals (5) are fixed, positioned above the flat spring (6), at a distance, and each of the contact terminals (5) is provided with a contact bump (11) positioned opposite to one of the contact bumps (4) riveted to the flat spring (6). Disk (2), positioned above the contact terminals (5), is connected to the base (1) by means of two symmetric supports (13) provided with springs (10), one end of which is fixed to the base (1) in such a way that the disk (2) can be pressed to the base (1) by the springs (10) and the flat spring (6).
