Abstract
The invention relates to an electrical switch, in particular for a motor vehicle, such as for an electric parking brake in the motor vehicle, having a movable operating member, in particular in the manner of a rocker, and a contact system, such that the operating member interacts with the contact system in a switching manner. The operating member interacts via an operating element, which is loaded with an elastic force, with a slotted link for generating a resetting force during the movement of the operating member out of an inoperative position. A further slotted switching link is provided. The operating member has a further operating element in such a manner that each of the two operating elements interacts with one slotted switching link each.
Claims14
An electrical switch, comprising an operating member that is movable from an inoperative position into a switching position and a contact system, wherein the operating member interacts in a switching manner with the contact system in the switching position, and wherein the operating member interacts via a first operating element, which is loaded with an elastic force, with a first slotted switching link for generating a resetting force during the movement of the operating member out of the inoperative position, wherein the electrical switch further comprises a second slotted switching link and a second operating element for the second slotted switching link arranged on the operating member in such a manner that each of the two operating elements interacts with the respective slotted switching link in the inoperative position and/or during the movement of the operating member out of the inoperative position, each of the operating elements comprising a pin arranged movably with respect to the operating member and a movement element having a radius, the movement element is mounted on the pin on a side lying opposite the operating member, whereby the movement element lies against the slotted switching link by means of the elastic force, each slotted switching link has rising flanks on opposite sides of the pin, which has a longitudinally extending center line that forms a line of symmetry between one side and an other side of the slotted switching link, such that the rising flank on the one side of the slotted switching link has a rising slope that is at an angle from the line of symmetry, a shallow slope that is at an angle from the line of symmetry that is greater than the angle of the rising slope and a steeper slope that is at an angle from the line of symmetry that is less than the angle of the rising slope, and the rising flank on the other side of the slotted switching link has a flat slope that is at an angle from the line of symmetry and a steep slope that is at an angle from the line of symmetry that is less than the angle of the flat slope, with the respective slopes of the rising flanks extending in that order away from the line of symmetry, such that each respective slope is connected to an immediately adjacent slope via a transition region having a radius that is greater than the radius of the movement element.
