FIELD: mechanisms.SUBSTANCE: invention relates to a mechanism for rotation of a packet switch containing mechanism handle (7) for switchover of the switch between open and closed positions, a crank lever, rotationally connected to mechanism handle (7), a spring connected to the crank lever (the spring has a dead point between open and closed positions of the switch), a force transfer shaft, rotationally connected with the crank lever, while mechanism handle (7), the crank lever and the force transfer shaft have a common rotation axis. Between the rotation of the mechanism handle and the crank lever there is set a rotary free play; there is also a set rotary free play between the rotation of the crank lever and the force transmitting shaft.EFFECT: technical result consists in provision of coupling operation speed.15 cl, 20 dwg |
