Definitions
- toggle switches For a number of areas of application, it has been found necessary that toggle switches must be watertight or dustproof.
- DE-GM 18 04 987 a proposal for a watertight mounting of the rocker arm on the housing cover of a switch is made. Another proposal for such a seal can be found in DE-GM 71 09 985.
- Another requirement addressed to these switches is that they should have an illuminated display which, on the one hand, should make it easier to find the switch in the dark (search function) and / or the switching status of the toggle switch or the function switched with the toggle switch (function display) ⁇ should show.
- the invention is therefore based on a switch of the type resulting from the preamble of claim 1. task
- the invention is to further improve such a switch by simplifying the shape of the housing and better protecting the luminous elements from environmental influences.
- the invention therefore consists in accommodating the luminaire itself in the closed chamber and in providing the housing itself with a suitable window through which the luminous flux can get into the interior of the button, where it then attaches in the usual manner Illuminated at the bottom of the button symbols or windows which serve to inform the operating personnel.
- the feature combination according to claim 2 is recommended in a further development of the invention.
- This feature is of course also when using several lights in the switch and also when using several lights applicable for one button.
- the specified construction is also very space-saving and creates additional sealing possibilities due to the steep lateral dome walls, as will be explained further below.
- a light guide connected to the cap and the button can, on the one hand, be close to the associated illuminated window on the housing and thus close of the filament, but on the other hand are removed from the filament by the pivoting movement of the key.
- the light guide can be arranged in such a way that the pivoting movement can at the same time bring the entrance angle of the light into a position which is particularly favorable for transmission and in the other case particularly unfavorable for transmission in the other case.
- a particularly favorable configuration for the light guide for the latter requirements can be found in the features of claim 5.
- the combination of features according to claim 6 is recommended in a further development of the invention.
- the light guide is then guided directly through the bottom of the cap, so that its end is visible to the viewer. The viewer can thus directly perceive the luminous flux emitted by the end of the light guide.
- the light guide can also have the side contour of a symbol, so that this symbol then lights up very strongly in the corresponding switching state.
- the feature combination according to claim 7 is recommended in a further development of the invention.
- Paint combination according to claim 8 The base body is inserted relatively deep into the interior of the housing or, in other words, the side walls of the housing are pulled down over the side surface of the base plate in order to protect it laterally against environmental influences.
- Additional protective measures can consist in preventing contaminants from reaching the side surfaces of the plug contacts of a plug to be inserted into the connector of the switch.
- the combination of features according to claim 9 is recommended.
- the plug contacts of the plug to be inserted are very carefully insulated from one another, which can be done by appropriate sealing material or by pouring the plug contacts into the plug.
- the outer contour of the plug can also be sealed off from the side walls of the housing by a corresponding sealing strip, so that neither dirt nor moisture can reach the preferably cutting-edge plug contacts of the switch.
- the combination of features according to claim 10 is recommended in a development of the invention, which can pivot the side panels when the button is tilted. Side walls of such spaces can be provided, for example, by the side walls of the housing bulges described above, which serve to receive the luminous elements.
- the screen is immersed, a labyrinth is difficult to overcome for dust or water.
- the recording space for collecting Dirt or moisture are used so that they cannot reach the high windows of the front surface of the housing.
- An additional measure to keep the front surface of the housing free can consist in the features of claim 11.
- the key covers the front surface of the housing like a screen.
- the switch according to the invention is not only suitable for receiving a single filament, but also for accommodating two or more filaments.
- the combination of features according to claim 12 is recommended in a further development of the invention. Thereafter, it is also possible to solve different tasks with the structurally identical switch in that the key is in different positions on the switch or the key cap on the Actuator is mounted.
- the feature combination according to claim 13 is proposed in a further development of the invention.
- three transparent bodies which are essentially in alignment with one another are provided, the first as a window in the front of the housing, the second as an opening or window in the actuator and the third as a translucent symbol or likewise a simple, possibly colored window are designed.
- FIG. 1 shows a longitudinal section through a switch according to the invention through a switch according to the invention
- Fig. 2 shows a possible connector for a switch according to Fig. 1 and
- FIG. 3 shows a cross section through the switch according to FIG. 1.
- the present description is based on DE-OS 30 24 510. Thus, only features are described which are new compared to this description and are essential for the present invention.
- 1 has a housing 1, the cast-on side walls 2 of which are pulled down far and thus serve to protect the terminal block of the base body 3. It is particularly important for the invention that the housing at its upper end in FIG. 1 has a continuous front wall 4 which is necessarily interrupted only in a small, carefully sealed area in which an extension of the key 5 into the interior 6 of the housing 1 protrudes.
- the base body 3 is pushed into the housing 1 from below and locked with it.
- contact knives 7, which are connected in a manner known per se to both the fixed and the movable contact pieces of a rocker contact.
- the contact knives are connected in a suitable form to two filaments 8 and 9, the filament 8 serving for functional lighting and the filament 9 for search lighting.
- the lamps are held in sockets connected to the housing.
- the connecting lines themselves can hold the luminous elements 8, 9.
- the sockets can also be inserted between the side walls of two bulges 10, 11 of the front wall 4 of the housing 1. be pinched.
- the mode of operation of the switching elements of the switch corresponds to that of the switch described in DE-OS 30 24 510 and is therefore not repeated here.
- the two luminous elements 8, 9 are arranged in the interior of the housing 1 and are covered by the continuous front wall 4. So that the luminous flux emitted by the luminous elements 8, 9 can also glow to and through the button 5, the front wall 4 is provided with two windows 12, 13, which are spherically curved, transparent and cast with the housing 1.
- the key 5 is sealed in a manner known per se (see DE-OS 30 24 510 or DE-AS 12 12 616 or DE-GM 18 04 987).
- the key 5 is composed of an actuator 14 and a cap 15, the cap 15 being snapped onto the actuator 14.
- the division of the key 5 results in a simplified casting mold and the possibility of using the cap 15 on the actuator 14 by twisting the switch 14 to use the switch according to the invention for other switching tasks.
- the sack-like receiving spaces 17, 18 formed in the front wall by the side walls 2 of the housing and the side walls of the bulges 10, 11 are particularly advantageous for the switch, since possible dust or possible moisture can be collected on the outer surface of the front wall 4 here.
- two ends 18, 19 attached to the side of the actuator 14 can dip into the receiving spaces 16, 17 and thus block the path for dust and water to the surface of the front wall 4.
- the windows 12, 13 and the seal 20 of the button 5 relative to the housing 1 are also free of dirt held.
- the receiving spaces 16, 17 can also be connected to one another by a circumferential groove into which a circumferential wall connecting the panels 18, 19 is then immersed.
- a light guide 21 can be locked or encapsulated with the cap 15.
- the light guide end 22 forms a window in the surface of the cap 15, which can be illuminated very brightly.
- the contour of the light guide end 22 can also be designed as a symbol at the same time.
- the shaft 23 of the light guide merges into a shell 24 which surrounds the arched window 12 in the front wall 4 and thus receives the luminous flux penetrating this window and passes it on to the light guide end 22 via the shaft 23. While the light transition from the window 12 to the shell 24 and thus to the light guide 21 is very easy in the position shown in FIG. 1, conversely, in a second tilting position of the button 5, not shown in FIG. 1, the shell is from the window 12 raised and set at an angle to this. Thus, the light coming from the window 12 can hardly enter the shell 24, as a result of which the operator is shown the switch position (not shown in FIG. 1) due to the dark end of the light guide 22.
- the second luminous element 9 is used, the radiation thereof via the window 13 and a recess 25 (which can also be designed as a window) in the actuator 14 and a translucent window 26 in the Cap 15 can reach the viewer.
- the window 26 can have the contour of a symbol and be cast into the cap 15 or else be translucent due to a corresponding weakening of the window area 26.
- FIG. 2 shows the possibility of designing a connector suitable for sealing the switch according to FIG. 1.
- the plug on the plug housing 29 can have laterally projecting tabs 30, 31 which, on the one hand in connection with the side walls 2, provide a seal between the plug 28 and the terminal strip of the switch and, on the other hand, a latching of the plug 28 in the switch housing 1 possible.
- the receiving contacts 32 to 37 can either be poured into the housing 29 for improved sealing or the surroundings thereof can be poured out by a sealing compound 33.
