Definitions
- the invention relates to a switch button for electrical switching devices with one movably arranged in a fixed guide Actuator.
- From DE-A-2 853 880 is a switch button for electrical Switch with a movably arranged in a fixed guide Actuator known, the actuator has a cylindrical slider, the outer surface is provided with a sliding element that with a in the stationary Guide provided, axially parallel to the cylinder axis of the Leading guideway is engaged, wherein between an annular gap between the slider and the fixed guide is formed, which is interrupted locally by the sliding element is.
- a switch button for electrical switches with one in a fixed guide movably arranged actuator, the actuator has a cylindrical slider, the Shell surface is provided with recesses in which rolling elements are arranged, which in turn with in the fixed Guide provided axially parallel to the cylinder axis of the guide running guideways are engaged, and wherein between the slider and the fixed guide formed an annular gap which is locally interrupted by the rolling elements.
- rolling elements are on Balls are provided which are in the recesses on the cylindrical Slider as in the guideways of the fixed guide each have point contact points.
- this embodiment can also roll-like rolling elements be provided which are tangential to with their rolling axis Lateral surface and perpendicular to the direction of actuation of the switch button are arranged and roll according to the switching stroke.
- the recesses can on the outer surface of the slider in certain azimuthal Distance to each other as well as a certain axial distance, e.g. B. depending on the intended switching stroke, may be provided.
- a certain axial distance e.g. B. depending on the intended switching stroke
- injection-molded plastic As material for the fixed guidance as well as for the design the guideways arranged therein is preferred injection-molded plastic provided, for. B. ABS or polystyrene. But instead it can also be based on metallic material, e.g. B. zinc alloy or aluminum alloy avoided if necessary become. Can also be used as a material for the slider a plastic molding compound or metal may be provided.
- the rolling elements can both from a Plastic molding compound as well as made of metal, for. B. Steel balls, usually the material intended for this of which for the guideways and for the slider is different.
- Switch button 10 with a movable actuator 12 and a fixed guide 14 shown.
- the switch button 10 belongs to a switch 16 shown only schematically here, whose technical function is not important here.
- the fixed guide 14 is arranged on the switch housing 16, which is designed as a hollow cylinder, in the interior 18 one belonging to the movable actuating element Slider 20 engages.
- the outward facing top of the Slider 20 is one of the cross section of the fixed Guide 14 overlapping button 22 formed.
- the Fixed guide 14 axially parallel to its cylinder axis Guideways 24 on the inside in their cylinder wall 25 are molded and with associated recesses 28 spatially on the lateral surface 21 of the slider 20 correspond.
- the Fixed guide 14 axially parallel to its cylinder axis Guideways 24 on the inside in their cylinder wall 25 are molded and with associated recesses 28 spatially on the lateral surface 21 of the slider 20 correspond.
