Definitions
- the invention relates to a large push button covering several small keypads a keyboard in an arrangement on a guide body for actuating Switch contacts according to the preamble of claim 1.
- Such a push button is disclosed in DE 33 29 698 A1, where it says: Individual Pushbuttons on typing keyboards are much larger than the other keys and large compared to the contact to be actuated. To tilt in the case of off-center To avoid actuation, two scissors are provided as a guide device. their both axes are aligned with each other. The four storage locations of the upper free ends of the arms enclose a rectangular surface which is in line with the actuating surface largely covers, therefore there is a concealed installation.
- the invention is therefore based on the object in a generic Push button device to find measures that one Deformation of the engagement slot and concealed mounting can be avoided.
- Fig. 1 shows a large, several small keypads 1 covering push button 2 for one Keyboard in an arrangement on a guide body 3 for actuating Switch contacts 4, in which a button plunger 5 is arranged in a on the guide body 3 Engages guide sleeve 6 and interacts with a switching dome 7 of a switching film 8, which is below the guide body 3, as can be seen from Fig. 2, in the one Side view of Fig. 1 is shown with partial section in the region of the guide sleeve 6.
- the key 2 has a bearing fork extension 9, the lever arms 10, 11th each have a bearing pin 12 which exists in the guide body 3 Engagement slots 13 engage, as can also be seen from Fig. 2, one on both sides first adjacent pair of guide sleeves 14 exist.
- one Version for a larger button can be provided, in which the guide slots of the second adjacent pair of guide sleeves can be used.
- the pivoted into the guide sleeve 6 key plunger 5 one in the
- the bearing fork extension 9 has a middle lever extension 17, which has a guide section 18 lying between the pair of guide sleeves 14 forms, the middle lever lug 17 may have a bearing portion 19 which received by the engagement slot 20 lying between the pair of guide sleeves 14 is, as can be seen in dash-dotted lines from FIG. 3.
- the bearing fork extensions 9, 17 and Key body 21 has a common offset 22, the total of the push button 2 dimensionally stabilized.
