Definitions
- the invention relates to a push button according to the preamble of claim 1.
- Such pushbuttons are used, for example, on keyboards from
- the reset part consists of an elastically deformable material and is cup-shaped. A contact point is provided in the center, which comes into contact with a push of a button with a conductor track of a circuit board on which the base part is arranged. At the push of a button, the wall of the reset part is deformed in an S-shape.
- the lower part of the key head is guided in a recess in the base part. This guide must ensure a tilt-free actuation of the button head, otherwise contacting the push button is not ensured. As a result of this guidance, the lower part of the key head is made relatively long and the recess in the base part is relatively deep.
- the object of the invention is to provide a flat push button, in which a tilt-free actuation of the button head is ensured.
- FIG. 1 is a vertical section through the push button. A " in the non-actuated state along the line A - A of Figure 3,
- FIG. 2 shows a vertical section through the push button according to FIG. 1 with the button head actuated along the line A - B of FIG. 3,
- Figure 3 is a horizontal section through the push button of Figure 1
- Figure 4 shows the intermediate part of the push button of Figure 1 in
- the push button consists of four parts, namely the base part 1, an intermediate part 2, a key head 3 and a reset part 4.
- the reset part 4 is cup-shaped and consists of an elastically deformable material.
- a contact surface 5 is arranged in the center on the bottom on a downward-pointing projection. When the button is pressed, it comes into contact with a printed circuit board 6 on which the base part 1 is arranged.
- the base part 1 has a circular cylindrical recess 7.
- Four grooves 8 are formed on the wall of the recess 7 and run obliquely to the key axis 9.
- a nose 10 is formed in each of these grooves 8 at the upper end.
- the intermediate part 2 is circular cylindrical.
- springs 11 are provided on the outer circumference of the intermediate part 2, the inclined course of which corresponds to the inclined course of the grooves 8.
- the springs 11 each have a nose 12 at their lower end.
- the springs 11 are in engagement with the grooves 8.
- the lugs 10, 12 abut one another, as is shown in FIG. 1.
- Four further springs 13 are formed on the inner circumference of the intermediate part 2, which also run obliquely to the key axis 9. The inclination of the springs 13 is opposite to the inclination of the springs 11.
- the lower part of the key head 3 is circular in cross section.
- the wall of the lower part 14 has four grooves 15.
- the grooves 15 have the same slope as the springs 13 which engage in the grooves 15.
- the intermediate part 2 performs a rotary movement as a result of the engagement between the grooves 15 and the springs 13 and as a result of the engagement between the grooves 8 and the springs 11 and as a result of their opposite inclination.
- This rotary movement is illustrated in Figure 2 by the arrow.
- This rotary movement also takes place when the key head 3 is only touched at its edge.
- the linear movement of the key head 3 is thus converted into a rotary movement of the intermediate part 2.
- the key top 3 does not rotate relative to the base part 1.
- the grooves 8 and 15 and tongues 11 and 13 preferably have a helical course.
- the upward movement of the key head 3 is likewise limited by lugs 16, 17 which are provided in the upper region of the springs 13 and in the lower region of the grooves 15.
