Definitions

  • the present invention relates to a key switch according to the preamble of claim 1.
  • Such a push button switch is known from CH-PS 595 687. It has the advantage that two different switches do not have to be made for the pushbutton and one for the latching function, and the consumer has to keep them in stock. The latter can set the pushbutton switches according to the desired function when they are used.
  • a linear groove-shaped curve is provided for the button function.
  • the pin is inserted into one or the other of the two curves. The arrangement of two groove-shaped curves in parallel next to each other takes up a lot of space. In addition, the pin is difficult to access with microswitches and it is only possible to see if it is in the correct curve if you look very closely.
  • the object of the present invention is to improve a pushbutton switch of the type mentioned in such a way that it can be carried out in a space-saving manner while maintaining its advantage, and the changeover can be carried out in a simple manner in the form of a microswitch.
  • the switch shown in the drawing essentially has a housing 1 in which a slide 2 is axially displaceably mounted.
  • the slide 2 is firmly connected to the pressure hood support 3 and is in its rest position (shown in solid lines in FIG. 1), in which it is held by an upward spring force and rests against an invisible stop on the inside of the housing.
  • With the housing 1 there is also a switching element 4 (indicated by dash-dotted lines) in which the switching contacts are accommodated. If the slide 2 is pressed in by a pressure on the pressure hood support 3 by the switching path S, it actuates the switching contacts accommodated in the switching element 4.
  • On the outside of the slide there is a curve 5 in the form of a groove with which a pin 6 is engaged.
  • the pin 6 is part of a lever 7, which is hooked with its upper hook-shaped end in a bearing 8 and is pivotally mounted therein.
  • the bearing 8 designed as a bearing eye is formed by a leaf spring 9 into which a shoulder 10 is molded.
  • the leaf spring 9 generates a force acting on the lever 7, which keeps the pin 6 in contact with the bottom of the curve 5.
  • the leaf spring 9 is held with a friction fit in a guide groove 11 on the inside of the housing and between the position shown in solid lines on the one hand and the position shown in broken lines on the other slidable. If, for example, the shoulder 10 is pressed by means of a screwdriver, the leaf spring 9 moves upward from the position drawn with solid lines into the position shown in broken lines.
  • the bearing 8 slides relative to the housing 1 or to the slide 2.
  • the leaf spring 9 has an opening 14 which is intended to snap into a locking lug 12 arranged on the inside of the housing when the leaf spring 9 has the same dash-dotted lines assumed position.
  • the latching cannot be released, which means that the leaf spring 9 cannot be reset.
  • This latching connection can, however, also be omitted if the friction fit of the leaf spring 9 in the guide groove 11 is sufficient.
  • a linear section 13 adjoins the heart-shaped curve 5 at the bottom, which is so long that in the rest position of the slide 2 the pin 6 is always in this extension, regardless of whether the bearing 8 is in in the lower or in the upper position.
  • the depth of the curve 5 (including the extension 13) varies and has different levels, as its development in Fig. 3 illustrates. If you follow the extension 13 from point a upwards and clockwise around the heart-shaped curve 5 back downwards, the bottom of the groove rises until a falling stop step b. From there, curve 5 runs to a descending step c, after which it rises again to a descending step d. Then it rises to a level e, after which it falls back to point a.
  • the switching path S of the slide 2 is smaller than the distance a of the pin 6 from the detent step b. If in this storage position the slide 2 is pressed down by the switching path S, the pin 6 only moves in the curve 5 to point f and returns to point a after the slide 2 is released. The slide 2 does not snap into place. If the bearing 8 is shifted to the dot-dash position in FIG. 1 (FIG. 2b), the switching path S of the slide 2 is greater than the distance of the pin 6 from the detent step b. Now, when the slide 2 is pressed down by the switching path S, the pin 6 follows the left branch of the curve 5 and exceeds the detent step b.
  • the slide When the slide is released, it moves upwards and the pin 6 follows the curve 5 to the bottom right and exceeds the descending step c. After this stage, the slide 2 engages with the pin 6 and prevents it from returning from the switching position to the rest position. The slide 2 is locked. If the slide 2 is now pressed a second time and then released, the pin 6 continues to follow the curve 5 clockwise and successively exceeds the descending steps d and e until it reaches the starting point a in the extension 13 again. Depending on whether the bearing 8 is in its upper or lower position, the pushbutton switch has a latching or pushbutton function.
