<p>The invented changeover switch with middle disconnecting position consists of a shaft (2) mounted in a frame (1) with possibility of angular displacement and being provided with a changeover blade (21). In extreme positions the changeover blade (21) fits in contact heads (12) located on insulators (11). On the shaft (2) there is fastened a couple of arms (31, 32). Each arm (31, 32) is joined with a linear motor (4a, 4b) whose other end is joined to the frame (1). Axis of each linear motor (4a, 4b) forms with said shaft (2) axis of rotation skew lines.</p> |
