  • the switch has a movable between an output and an actuating position actuating member which cooperates in its movement with the switching contact for switching the contact system.
  • a movable latching means cooperate latching with the actuator in the operating position.
  • GB 2 110 472 A discloses an electrical switch with a contact system consisting of a movable switching contact and fixed contacts.
  • a movable actuator acts in its movement with the switching contact for switching the contact system together.
  • the actuator is operatively connected to a spring-loaded lever in that the lever passes through a receptacle in the actuating member approximately transversely, such that the lever performs a pivoting movement during movement of the actuating member.
  • the pivoting movement of the lever in turn moves the switching contact for switching.
  • this switch has an implementation of the traversed by the actuator path through the lever.
  • the pivoting movement of the lever in particular on the spring bearing, afflicted with considerable tolerance problems and leadership inaccuracies, which in turn increases the required stroke of the actuator and the actuating force.
  • these problems prevent the use of the switch for higher performance.
  • the invention is based on the GB 2 110 472 A the task of specifying a suitable for switching high power electrical switch with a small actuation path.
  • the electric switch should be used as a power switch in equipped with short-stroke keys panels to be adapted to the operating philosophy of today's home appliances.
  • the operating force for the electrical switch should not increase significantly.
  • the actuating member is in operative connection with a lever, such that the lever performs a pivoting movement during movement of the actuating member.
  • the pivoting movement of the lever in turn moves the switching contact for switching. Due to the pivotal movement of the lever, a magnification translation of the path traveled by the actuator is achieved, so that even a small actuation travel of the actuator, the switching contact with a sufficiently large way emotional.
  • a contact opening width of more than 3 mm is made possible even with a short actuating travel, so that the switch according to the invention is suitable both for switching high loads and control currents.

  • the lever is designed as a one-armed lever.
  • the bearing is then located at one end of the lever.
  • the contact system is designed as a snap-contact system.
  • the switching contact is designed as a snap-switching contact, so that the switching contact switches over when snapping the lever between its two end positions.
  • the switching contact is pivotably mounted in a knife-edge bearing, which can be arranged for example on an electrical connection.
