Abstract
An electrical switch has a geometrically reproducibly precise switching point. The switch includes a housing defining a bore therein; an electrically conductive ball disposed within the bore and movable therein; two contact elements fastened in the housing; an elastic element disposed in the housing for pressing the ball against the contact elements such that the ball rests against the contact elements at respective contact points thereby establishing an electrically conductive connection between the contact elements; a plunger element operatively contacting the ball and being movable for lifting the ball off from the contact elements counter to a pressing force of the elastic element for interrupting the electrically conductive connection between the contact elements; and an adjustment element operatively contacting the ball for limiting a margin of movement thereof in a direction essentially perpendicular both with respect to a longitudinal axis of the bore and with respect to an imaginary line connecting the contact points.
