Patent ID: 8324520

Claim:
A disconnector, comprising: a cam wheel, via which, the disconnector is switchable on and off, the cam wheel being mounted so as to be rotatable between two limit positions, one limit position corresponding to a switched-on state and the other corresponding to a switched-off state of the disconnector; two cams, formed on the cam wheel, located opposite one another and extending transversely with respect to a rotation axis of the cam wheel, wherein the two cams include an external contour with an apex point; two pressure elements, each resting on the external contour, to apply force and press against the cams, each of the two pressure elements producing a torque during rotation of the cam wheel after passing over the apex point, the torque automatically rotating the cam wheel further to the respective limit position; a rotatable first operating element, whose rotation axis runs transversely with respect to the rotation axis of the cam wheel and on which a pivoting element is arranged, wherein the pivoting element extends outward transversely with respect to the rotation axis of the first operating element; two protuberances, arranged between the cams with an angular separation on the cam wheel, wherein the pivoting element extends into the space between the two protuberances, presses against one of the protuberances during pivoting, and in the process rotates the cam wheel beyond the apex point in the direction of a limit position; a holding opening, formed in the cam wheel and running in a direction of the rotation axis of the cam wheel; a second operating element including a body, mounted in the holding opening so as to be rotatable with an angular play; and two stops, to limit the angular play and about which the cam wheel is rotatable by the second operating element beyond the apex point in the direction of a limit position.
