Definitions

  • the present invention relates to a switch consisting of an upper base block and a lower base block; Line connection means, at least one of which is connected to a stationary contact pin; and an actuating mechanism which has a movable actuator and contact element mechanism to be actuated via a toggle button or the like to form an electrically conductive current path via said actuator and contact element mechanism between at least two line connecting means.
  • the contact pins are either in a horizontal or vertical position.
  • the advantage of the horizontal design is the short switching travel; reference is made to the publication US-5051550.
  • a contact rocker supported in the middle is actuated, which rocks with one quick movement against one of the two horizontal contact pins.
  • a vertical contact arm is firmly connected to the rocker button, which causes the rocker button to swing to the right or left against the vertical contact pin becomes.
  • the present invention is primarily intended to create a new type of movable actuator mechanism with which disadvantages of conventional switches can be eliminated and a new type of compact switch can be produced.
  • the actuator and contact element mechanism comprises a preferably centrally supported or mounted contact rocker, which can be rocked about an unstable, horizontal equilibrium position between a first and a second end position via the toggle button, and to which a firmly and electrically conductive contact can be made downward contact arm connects, at whose free lower end said movable contact pin is arranged, and which presses the movable contact pin against the stationary contact fit at least in the mentioned end positions in the case of a pendulum-like moving contact rocker to form an electrically conductive current path.
  • the solution according to the invention has made it possible to combine the rapid contact movement inherent in the horizontal construction and the small lateral space requirement of the vertical construction, which has the advantage of a reduced size of the switch and a fast and reliable contact.
  • the base of the switch according to the invention comprises an upper base block 1 and a lower base block 2.
  • the base blocks 1 and 2 are connected to one another is not relevant with regard to the present invention or its function, but it can be found that the base blocks advantageously via a releasable snap mechanism, for example a clamp connection (not shown in the figures) are interconnected.
  • the line connection means 22 and 22 'located in the side chambers 21 can be separate or can be connected to one another via optional bridge circuits, as a result of which one and the same base construction can be adapted to the most varied of needs and applications.
  • a stationary contact pin 23 is fixedly and electrically conductively connected to the left line connection means 22 of the line connection means 22 located in the opposite side chambers 21, 21 ', which is in the middle chamber 20, in its lower part is carried by an electrically conductive support arm 24 such that the contact surface of the stationary contact pin 23 forms an angle between 60 and 120 ° with respect to the unstable horizontal equilibrium position of the contact rocker 26.
  • the contact rocker 26 in the lower base block in the middle chamber 20 on the underside becomes central, from the electrically conductive free end of a mainly horizontal one Support arm 25 supported, which support arm is connected at its other end to the right of the opposite line connecting means 22, 22 '.
  • the contact rocker 26 is firmly connected on the underside to a vertical, electrically conductive contact arm 27, at the free end of which a two-sided contact pin 28 is arranged which is moved by the contact arm moved by the contact rocker in a pendulum motion.
  • the contact arm 27 and the contact rocker 26 are formed from a single metal strip bent in shape and angle, the contact rocker part being a horizontal part that can be rocked relative to the unstable horizontal equilibrium position of the contact rocker, and the contact arm part is being a vertical part be formed, which moves as a result of the movement of the contact rocker pendulum.
  • the rocking movement of the contact rocker in relation to its unstable horizontal equilibrium position is 0 to 30 ° and the deflection angle of the contact arm 27 and the contact pin 28 which thus oscillates in a pendulum-like manner in both directions is 0 to the vertical plane perpendicular to the unstable horizontal equilibrium position of the contact rocker 30 °, the contact with the stationary contact pin 23 being optimal.
  • the top 29 of the contact rocker 26 functions as a sliding surface 14 for the cam of the actuation mechanism 10 arranged in the upper base block 1.
  • the upper base block comprises a lever-like movable actuation mechanism 10.
  • the switch according to the invention is to the outside, ie upwards in the figure, a lever-like toggle button 10 is visible.
  • Below the toggle button 11 is a cavity in which a downwardly open sleeve member 12 and in the sleeve member 12 Cam mechanism 13 are arranged.
  • the sleeve member 12 is not necessary because the cam mechanism can of course also be arranged directly in a cavity of the toggle button 11.
  • the cam member 14 is pressed down by a spring member 15 against the top of the horizontal contact rocker 29, which thus serves as a rocking sliding surface for the tip of the cam member when the rocker button is moved between the end positions.
  • the horizontal support arm 25 of the contact rocker 26 is connected to another, i.e. in the figure connected to the right, line connection means 22 ', and in order to form the current path in question, the toggle button is to be taken from the end position shown in the figure, where the electrically conductive current path between the line connection means 22' located in adjacent side chambers 21 ' is established, can be switched to the other end position.
  • the tip of the cam member 14 is wedge-shaped, and that the sliding surface of the contact rocker 26 for the cam member 14 is designed to have a straight central portion 291 and upward inclined edge portions 292.
  • a stop zone which limits the sliding movement of the tip of the cam member 14 and determines the end positions.
