Definitions
- the invention relates to a push button for latching and push button function according to the preamble of claim 1 and serves to actuate at least one contact element.
- a generic push button which consists of a hollow cylindrical housing and a switching plunger which is guided in a longitudinally displaceable and non-rotatable manner.
- the switching plunger is acted upon by a helical compression spring in the direction of the rest position, for which purpose stop lugs on the switching plunger and corresponding stop surfaces on the housing are provided.
- In the outer wall of the switching plunger there is an approximately heart-shaped latching link and, parallel to and separately from it, a longitudinal groove running essentially in the direction of actuation.
- a wire-shaped spring element which extends essentially in the direction of actuation and whose bent free end is designed as a guide pin, is mounted in the housing.
- the guide pin runs in the latching link or in the longitudinal groove and can be converted from the latching link into the longitudinal groove or vice versa by means of a pointed tool that reaches through an access opening in the housing.
- the disadvantage is the complex storage and the additional spring means that take up space and thus take up space in the design of the spring element.
- the guide pin is also difficult to implement accessible and its actual location only recognizable when you look very closely.
- a illuminated pushbutton with locking function from Moeller GmbH with the type designation RLTR is known, in which the heart-shaped locking link is embedded in the inner wall of the housing and the guide pin engaging in the locking link protrudes outwards from an open metal ring which is mounted on the switching plunger ,
- the housing is equipped with two locking links arranged opposite each other and the spring ring with two guide pins opposite.
- the invention has for its object to provide a push button for locking and push button function with a simple and space-saving mounting of the guide pin and with an easy to perform and recognizable change in the type of function.
- the locking link and the longitudinal groove on the inner wall of the housing and the guide pin as part of the ring element, no additional space is required compared to a push button that is only equipped with a locking function or with a push button function.
- the open ring element is suitable for being easily snapped into a corresponding annular groove on the switching plunger during assembly and then being mounted there in a slightly displaceable manner.
- the outward-pointing guide pin can be moved slightly clockwise or counterclockwise with a suitable pointed tool, the respective end position of the the function of the push button is clearly recognizable through the access opening with a clearly visible guide pin.
- the invention is advantageously further developed by a cross connection connecting the latching link and the longitudinal groove approximately at half height.
- the guide pin can only be deliberately changed over when the pushbutton is in the half-pressed position, whereas in the two end positions, an unintentional adjustment caused by vibrations or shocks is excluded.
- the cross connection can expediently be designed at the same time as an access opening.
- An expedient further development consists in the design of the locking link and / or the longitudinal groove, which ends at the front, in order to provide the guide pin with easy entry into the locking link or the longitudinal groove when the push buttons are assembled.
- An opposite arrangement of the guide elements responsible for the latching and push-button function serves the reliable functioning of the push button.
- FIG. 1 a push button according to the invention in a half-pressed position in a perspective view
- FIG. 2 the pushbutton according to FIG. 1 in a partially broken away and exploded perspective view
- FIG. 3 a detail from FIG. 2. Best way to carry out the invention
- the pushbutton 2 for the latching and pushbutton function essentially consists of a hollow cylindrical housing 4 and a switching plunger 6 which is longitudinally displaceable and non-rotatably therein.
- a helical compression spring also not shown, which is placed around the lower part 10 of the switching plunger 6 and which is supported between a rear-facing ring surface 12 on the central part of the switching plunger 6 and a forward-facing partial ring surface 14 of the housing 4, the switching plunger becomes 6 forward, ie against the direction of actuation 16, acted upon.
- the switching plunger 6 When the switching plunger 6 is inserted into the housing 4, the two radially projecting, elastic plunger ends 18 are snapped behind the rear abutment surfaces 20 of the housing 4 and then, in cooperation with the compression spring, ensure that the pushbutton 2 is in the rest position.
- reference number 22 is an external thread on which a mounting nut can be screwed onto the housing 4 from behind.
- the switching plunger 6 is held in the housing 4 by a snap-on front ring 23.
- the essentially cylindrical inner wall 24 of the housing 4 is provided with two diametrically opposite recesses 26, of which only the rear one can be seen in FIGS. 2 and 3.
- Each of these indentations 26 consists of an approximately heart-shaped latching link 28, a longitudinal groove 30 running parallel to this and in the actuating direction 16, and a transverse connection 32 connecting the latching link 28 and the longitudinal groove 30 approximately in their middle height.
- the latching link 28 surrounds an approximately inverted heart-shaped island 34.
- the locking link 28 and the longitudinal groove 30 run towards the front into an inner rounded portion 36 of the housing 4 and are separated below this point by a tongue-shaped web 38.
- An open ring element 42 is mounted in an annular groove 40 in the central part of the switching plunger 6, so that it can be turned easily.
- Two diametrically opposite guide pins 44 are formed on the ring element 42. det, of which only the front one can be seen in FIGS. 1 and 2.
- the guide pins 44 slide along either within the locking link 28 or within the longitudinal groove 30.
- the pushbutton 2 functions in a latching manner, the respective guide pin 44 latching below the island 34 which is in the shape of a reverse, in the depressed position.
- pushbutton 2 is groping. At least on one side, the guide pin 44 is visible through an access opening 46 recessed in the housing 4 when the switching plunger 6 is pressed halfway, as can be seen in FIG. 1.
- the guide pin 44 can be displaced clockwise or counterclockwise with the aid of a suitable tool which extends through the access opening 46.
- the guide pins 44 slide along the transverse connection 32 in order to get out of the latching link 28 into the longitudinal groove 30 or vice versa.
- the rear wall is eliminated by the formation of the access opening 46 at the same point.
