The invention relates to a microswitch with at least two contact points, each with a moveable contact and a fixed contact, wherein the moveable contacts are arranged on a contact link, the contact link is capable of being moved by means of a plunger and can be moved over from a first switching position, in which contact points are open, into a second switching position, in which contact points are closed. During use of the microswitch, dirt may be deposited on the contacts, this having a disruptive effect on the microswitch, and in the worst case scenario, results in there no longer being a current flow in the closed position of the contact points. The intention is therefore to provide a microswitch with reliable self-cleaning. In this regard, the invention provides that the contact link is mounted in such a way that the contact link performs a rotary movement about an axis of rotation, which runs parallel to the longitudinal extent of said contact link, during closing and opening of the contacts, as a result of which a forced frictional movement transversely with respect to the longitudinal extent of the contact link takes place between the mutually opposite contacts of each contact point.
