Definitions

  • the invention is based on a key switch with one or more key plungers guided and sprung in a support body with a defined end position and with one contact set per key plunger, the contact sets being designed as a mechanically and electrically connected microswitch on a circuit board that can be physically separated from the support body, and wherein each push button for the assigned microswitch has an actuating finger.
  • Such a key switch is known from DE-U-86 11 125.
  • the button plunger transmits the pressure force introduced into the push button unchanged via a push button to the microswitch, which is subject to risk of destruction if force is applied too much.
  • the known key switch is housed in a surrounding housing that is closed together with the printed circuit board.
  • this requires a large amount of components.
  • the closed nature of the housing considerably limits the design freedom of the designer. For example, there are no other components below the housing can be grouped on the circuit board as only the microswitch assigned to the key switch. This also means that the choice of installation location for the microswitches is very limited.
  • the invention has for its object to limit the actuation force for the microswitch to a harmless level in a key switch of the type mentioned by suitable and yet inexpensive measures and a free choice of components of the key switch as free as possible free arrangement of microswitches with unchanged design of the support body to enable.
  • this object is achieved in that the actuating lever on the key plunger is displaceably guided in its actuating direction and is held freely in front of the microswitch by means of a spring acting in this direction when the key plunger is triggered and presses the microswitch with a spring tension when the key plunger is actuated than the actuation force required for the microswitch, and in addition that the support body has at least three supports extending in the direction of the printed circuit board, at least two of which have an abutment surface with a defined distance from the actuation finger when the key tappet is triggered and at least one of the supports has a latching lug, whose latching surface lies at a distance from the contact surfaces which is matched to the thickness of the circuit board.
  • a major advantage of the key switch according to the invention over the prior art is that its novel design enables the arrangement of microswitches to be freely selected with the support body unchanged.
  • the key plungers of such a key switch have short actuation paths and require only minimal actuation forces.
  • Another major advantage is that relatively generous tolerances can be allowed for the arrangement of the microswitches on the circuit board, because the key tappet, even when actuated, never reaches the microswitch itself into its defined end position and could possibly damage it due to excessive pressure.
  • the actuating finger is provided, which is to be regarded as a length-compensating link between the microswitch and the key tappet.
  • the advantage is also not insignificant that, in the event of a defect in the key switch, only the mechanical or only the electrical part has to be replaced, which may reduce the need for repairs.
  • the support body for holding the circuit board Due to the mechanical design of the support body for holding the circuit board, it can be assembled and disassembled without the use of tools. To loosen the fastening of the circuit board, all that is required is the deflection of the support or supports provided with the latching lug; and the circuit board can be removed from the support body.
  • the microswitches of the printed circuit board have a defined position in relation to the actuating fingers of the key tappets, so that it is not possible to mix up the microswitches to be actuated with regard to the respective key tappets.
  • the actuating finger is designed as a pin guided in an axial bore of the key tappet and the spring is a compression spring arranged in the axial bore under the pin, this results in the assembly of the support body and for its connection to the printed circuit board cheapest and safest because of its simplicity.
  • the key tappet 1 is held in the supporting body 2 and is guided in the longitudinal direction in its actuating direction.
  • the button plunger can be moved onto the microswitch 4.
  • the microswitch is soldered into a printed circuit board 5, which in turn is held on supports 6 of the supporting body 2 at a distance A from the key plunger 1 and by a support 7 with a detent 8 on the contact surfaces 9 of the supports 6.
  • the distance between the contact surfaces 9 of the supports 6 and that of the locking lug 8 is matched to the thickness D of the printed circuit board 5.
  • the key tappet 1 is pulled outwards on the one hand by a compression spring 10, but is held in a defined rest position by a switching heart 11 which works together with a sliding block 12 (only indicated schematically here).
  • An actuating finger 14 is guided in a coaxial bore 13 of the key tappet 1 and held in a defined position within the bore by a compression spring 15.
  • the button plunger 1 moves together with its actuating finger 14 towards the microswitch 4.
  • the spring 15 begins to tension under the actuating finger 14.
  • the tensioning force of the spring 15 exceeds the actuating force of the microswitch 4 during the further movement of the key tappet 1, the microswitch is switched. From this point on, the spring 15 continues to be tensioned by the actuating finger 14 until the key tappet 1 has reached its stop defined by the switching heart 11 and the setting 12. This stop is in any case before reaching the microswitch 4 through the end face of the key tappet 1, if the key tappet can emerge from the support body 2 differently than shown here.
  • the key switch shown as an example can also be designed without a switching heart 11 and a setting 12. Then the microswitch 4 is actuated only as long as the key plunger 1 is held down with its actuating finger 14.
  • the microswitches used can be set up with simple on or off switches, changeover switches or multiple switches and for switching low currents and voltages or even high currents (up to approx. 16 A) with household mains voltage (approx. 220 V).
