Abstract
An electrical switch, particularly for a breaking circuit includes first and second changeover switches. The first and second changeover switches each comprise first and second stationary contacts and a switching contact. A plunger is operatively connected to a rocker for causing the rocker to pivot between a non-operated position and an operated position. The second stationary contacts are associated with the non-operated position of the plunger. A spring is connected between the rocker and the switching contacts. The spring is arranged on the rocker and on the switching contacts so that at least when switching over from the second stationary contacts to the first stationary contacts the switching contacts are lifted off the second stationary contacts essentially synchronously. A delay device is coupled to the switching contact of the first changeover switch for only delaying movement of the first switching contact of the first changeover switch when switching over from the first stationary contact to the second stationary contact after that switching contact has lifted off the first stationary contact. The switching contact of the first changeover switch thus comes to rest against its second stationary contact later than the switching contact of the second changeover switch comes to rest against its second stationary contact.
