A key assembly to be installed on a keyboard is provided. The key assembly includes a base plate including a snap-fit hook, a scissor member including a pivot shaft, and a keycap. The keycap is disposed on the scissor member and connected thereto. The scissor member is disposed on the base plate and connected thereto. A bending portion of the snap-fit hook has a chamfer structure to which the pivot shaft is pivotally connected in such a manner that the vertical gap between the snap-fit hook and the pivot shaft is reduced.

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.
