Definitions

  • the invention relates to an electrical switch according to the preamble of claim 1.
  • Electrical switches for example for actuating coffee machines, should be liquid-tight or largely liquid-protected and illuminated. So that liquid cannot easily penetrate into the switch, known switches are possibly manufactured with a sealed housing or with an additional rubber seal on the actuator. However, such known switches are of complex construction and are particularly unsuitable for automatic assembly.
  • the invention has for its object to propose a largely liquid-protected switch, which is simple in construction and which is particularly suitable for automatic assembly.
  • this switch first upwards, i. H. in the direction of the actuating member is as liquid-tight as possible, but at least is protected from liquid. This takes place in the switch according to the invention in that the switch housing is almost closed at the top and leaves only a small opening for carrying out the actuating plunger for the contact bridge.
  • the switch housing is designed to be completely open, with special measures being provided which allow the individual parts to be assembled automatically. If, due to careless handling of the user, liquid gets into the switch interior through the upper plunger opening, this liquid can quickly and easily get out of the switch through the large bottom opening.
  • a large bottom opening in the switch housing offers the possibility of inserting the individual parts to be arranged inside the switch by an automatic assembly process, since only straight-line loading is provided.
  • longitudinal grooves, receiving slots, channels or the like are provided, which serve to receive the contact system or a possible lighting with connections.
  • the switch housing is advantageously rectangular or square, the actuator being designed as a rocker.
  • a rectangular housing shape enables the construction of a very space-saving switch.
  • two plug connections without lighting and three plug connections with lighting arranged side by side in the switch housing.
  • a raised collar is used on the upper part of the housing, which protrudes far into the rocker of the actuator and thus seals off the inside of the switch.
  • the raised collar can also have lateral trunnions for the rocker bearing.
  • the plug connections are designed as a contact system.
  • the middle connector has a cutting edge bearing for the contact bridge, which at the same time forms the electrical contact connection.
  • the external connector is bent at a right angle to form the mating contact surface for the contact bridge.
  • the inner housing wall and / or the plug connections have projections or resilient tabs for mutual locking when the plug connections are inserted into the interior of the housing.
  • the switch is provided with a lighting unit, this is embedded in a separate hole, with the series resistor also being arranged in a separate hole when using a glow lamp.
  • the switch housing is made very thin in the area of this lamp holder, so that the light shines through with almost no loss if the housing material is transparent. In this area, the rocker carries a window for light to pass through.
  • the cable connections of the lighting unit are made by means of notches on the plug connections, the notches being compressed after the connecting wires have been inserted.
  • the formation of the contact bridge with legs arranged in a U-shape is also advantageous.
  • the lower longer leg is used to connect the middle connector to the external connector.
  • the upper leg serves as an actuating surface for the rocker pin.
  • the contact spring is cut out in a semicircle in its outer area facing the glow lamp, so that the components can move closer together in this area.
  • FIGS. 1 and 4 represent a side view in cut-away form
  • FIGS. 2 and 5 the respective end view of FIGS. 1 and 4 and FIGS. 3 and 6 a view from below through the bottom opening of the switch housing.
  • the electrical switch 1 shown in side view in FIGS. 1 and 4 is preferably designed as a rocker switch for a coffee machine.
  • the rocker switch has a housing 2 which is completely closed on the side, the housing wall of which continues upwards and forms an upper housing end 3. Only in the central area of the rectangular housing 2 is a through opening 4 provided in the upper housing end 3, through which a switching pin 5 of the wiper-shaped actuating member 6 projects into the housing interior 7.
  • the upper housing end or the upper housing part 3 is designed in the form of a raised collar 8, which protrudes as far as possible into the cup-shaped housing 9 of the actuating member 6 in order to achieve the most comprehensive possible sealing of the through opening 4 to the housing interior 7.
  • the raised collar 8 has laterally protruding knobs 10, which serve as bearing pins for the actuator 6.
  • the housing 2 of the switch is completely open in its lower region through a bottom opening 11. 3 and 6 show an insight into this bottom opening from below.
  • a first, middle plug connection 12 is inserted into the housing 2 in the central region of the switch housing 2.
  • the side housing wall 13 points from bottom to top, i. H. in the vertical direction directed longitudinal grooves 14 or receiving slots or channels in which the flat connector 12 is inserted with its side edges.
  • the housing wall 13 laterally contains a bore 15 into which a lateral projection 16 of the plug connection engages, so that the plug connection and the wall engage with one another.
  • the plug connection 12 is U-shaped, the lower horizontal crosspiece between the U-shaped legs being designed as a pointed or V-shaped cutting edge 17, which is used as a bearing for the spring-like contact bracket 18 and at the same time serves as an electrical connection between the connector 12 and the contact bracket 18.
  • the contact bracket 18 has a lower longer leg 19, a V-shaped kink 20, a U-shaped arc 21 and an upper shorter leg 22.
  • the V-shaped kink 20 serves as a counter-bearing to the V-shaped cutting edge 17 of the plug connection 12.
  • an electrical contact 23 is provided which interacts with a contact 24 of a second, outer plug connection 25.
  • This outer plug connection 25 also consists of a flat material, with a tongue 27 bent between two U-shaped legs 26, which carries the electrical contact 24.
  • the side edges of the outer plug connection 25 in turn run in lateral longitudinal grooves 28 in the housing wall 13.
  • a rear nose or a projection 29 on the plug connection 25 serves for the positive locking of the plug connection 25 with respect to the housing 2 with a corresponding recess.
  • the switching pin 5 cooperates with its lower end with the upper, shorter leg 22 of the contact bracket 18 in the sense of a switch changeover.
  • the switch contact between the contacts 23, 24 is open, i. H. the lower leg 19 is raised from the contact 24 and is placed slightly obliquely upwards. If you press the actuator 6 in the other direction downwards, the contact bracket 18 snaps over, so that the contacts 23, 24 lie together and the lower arm 19 lies approximately in a horizontal position.
  • the electrical switch 1 additionally has an illumination device 30 in the form of a glow lamp.
  • the embodiment without lighting device, ie without glow lamp, is shown in Fig. 4 to 6, wherein the housing design is provided for receiving such a lighting device.
  • the housing design for receiving an illumination device 30 can therefore also be described with reference to FIGS. 4 to 6.
  • the interior of the housing 2 has an upwardly arcuate recess 32 which already has the shape of the glow lamp 30.
  • the housing material 33 is made transparent, so that the light from the glow lamp 30 can pass through it almost without loss.
  • the actuating member 6 carries a transparent window 34 (see FIG. 1), so that the light from the glow lamp 30 can also shine through upwards.
  • the window 34 as shown in FIG. 4, can be omitted.
  • the housing 2 has a further longitudinal recess 35, in which the series resistor 36 of the glow lamp 30 is introduced. Finally, a further, slot-shaped longitudinal recess 37 is provided, into which the third plug connection 38 is inserted in the case of an illumination unit 30. As already with the plug connections 12, 25, projections or resilient tabs 29 also serve for the mutual connection with the housing.
  • the first connecting wire 39 is connected to the middle connector 12 and the second connecting wire 40 is connected first to the series resistor 36 and from there (wire 40 ') attached to the third connector 38.
  • the middle connector 12 and the third connector 38 have notches 41 into which the connecting wires 39, 40 'of the glow lamp bwz. of the series resistor. By compressing these notches 41 in the region of the arrows 42, the connecting wires 39, 40 'are clamped in a non-positive and positive manner.
  • the relevant design of the connector 12 is also shown in FIG. 5.
  • the contact bracket 18 has in the region of its U-shaped arc 21 a semicircular recess 43 which is intended to serve as a recess for the outer contour 44 of the glow lamp 30.
  • the glow lamp 30 can move very close to the contact bracket 18 without the freedom of movement of the contact bracket being impaired.
  • the lateral housing walls 13 of the housing 2 also have longitudinal grooves 45 for the laterally protruding part 46 of the U-shaped arc 21 of the contact bracket 18. These longitudinal grooves 45 also serve for lateral guidance of the contact bracket 18.
  • the assembly of the individual parts of the switch 1 takes place, apart from the actuator 6, exclusively through the bottom opening 11.
  • the contact bracket 18 is first inserted and fixed by means of the central plug connection 12 in the region of the V-shaped cutting edge 17 with the counter bearing 20. Then the second connector 25 is inserted straight into the housing.
  • the one connecting wire 40 of the glow lamp 30 is already connected to the series resistor 36. After inserting these two parts into the recesses 32 and 35, the one Connecting wire 39 of the glow lamp inserted into the notch 41 of the middle connector 12 while the wire end 40 'of the series resistor 36 is inserted into the further notch 41 of the third connector 38. The two notches are then compressed with a certain clamping force and the wires are thus fixed (arrow 42).
  • the invention is not restricted to the exemplary embodiment shown and described. Rather, it also encompasses all professional developments and refinements without their own inventive content.
