Definitions
- the invention relates to an electrical switching device, in particular switches or pushbuttons for household machines, with a housing, in the interior of which at least one movable contact part and the projection of the actuating member controlling the contact part are arranged, in this case the one-piece contact part has a power connection at one end and on its other end has a contact for power transmission.
- Such devices are widely used.
- the configuration of the contact part in particular its long length, ensures good contact, since the contact part has a long spring travel.
- attaching the power line was a disadvantage, since a plug connection was required for this, in other words, the conductor to be connected had to be specially prepared, so that this switch, despite its good functionality, did not fully meet mass production.
- the object of the invention is therefore to design a switching device of the type mentioned at the outset in such a way that a good and reliable connection to the power supply is ensured when there is good contact.
- the switching device should be able to be easily equipped with different actuators.
- the power connection is designed as a screwless connection terminal and in that the switching attachment and the contact part provided with the contact are provided next to a side wall of the housing.
- These measures make it easy to connect a conductor.
- the arrangement of the switching lug sideways next to a side wall allows a good interior design inside the switch housing, so that the function of the switch housing or the mode of operation of the switch can easily be changed, for example by inserting differently designed actuators.
- the switching approach is arranged between the housing wall and the contact part. This measure allows the contact part to be easily moved when the attachment is moved.
- the clamping spring of the screwless terminal block in one piece with the contact part, in order to obtain fast and inexpensive production, so that the switch is suitable for mass production, and the contact part also has a high resilient effect on its contact contact.
- the angular contact part lies in one plane up to its power connection, in this case one angle arm carries the contact and the contact point for the actuator attachment, while the second arm has the screwless connecting terminal.
- This measure in particular the formation of the contact part in one plane, in turn enables the switchgear to be designed in a safe manner, so that such switches can be built small and without great expenditure on screws.
- the contact part with the touch contact receives a high spring force.
- clamping spring of the screwless connection terminal resiliently rests against an extension of the contact part which is designed as a continuation, since this enables safe current transmission from a conductor to the contact part, and the space requirement of such an arrangement is also small.
- the switching projection of the actuating element is advantageously provided with a projection which is perpendicular to its direction of movement and the housing wall and which is directed towards the movable contact part lying to the side. This measure allows a safe switching or movement of the contact part as soon as the projection moves the contact point of the contact part against the projection.
- the switch housing has a receptacle in which different actuators Type can be used with their switching approach, both rocker-type and push-button-type or shift actuators can be used.
- the advantage of the invention is that the interior design of the switchgear housing is provided in such a way that the switching approaches of the actuators of different movable actuators can easily transfer the contact part into its open or closed position.
- the movable contact part is constructed from two movable individual contacts, the two individual contact parts advantageously having the same structure and being rotationally symmetrical to one another in order to form the overall contact part. In this way, it is possible for the movement of the two parts of the individual contact parts carrying the contacts to be very close to one another, since both parts are evenly separated from one another during a movement to disconnect the power connection, so that the distance between the contact parts is doubled.
- a switching approach is advantageously provided for each individual contact part in order to be able to control both individual contact parts simultaneously in this way. It is advisable for the switch housing to be provided with a lamp which lies essentially above the screwless connection terminal which is connected to the lamp in an electrically conductive manner with an extension. In this way, the second line of the glow lamp can then be supplied with current by a second screwless connection part, in this case a further current conductor can then be inserted into the second screwless connection terminal in order to justify the power supply.
- the connecting wires of the lamp are used as an abutment against the contact part or the screwless connecting terminal or the additional screwless connecting terminal.
- the contact part has an F-shape, in this case the upper end of the F is provided with the screwless connecting terminal, while the middle arm of the contact has a counter-projection for the switching projection of the actuating member.
- the screwless clamp is clamped in the switch housing in order to achieve a secure mounting for the connection terminal and to fully utilize the spring action of the contact part.
- the F-shaped contact part advantageously carries a contact point at the two ends of its longitudinal web for the transverse arms. In this way it is impossible to arrange the contact parts in a rotationally symmetrical manner with respect to one another, so that there is a double current transmission.
- the switch housing has a tubular recess for receiving a compression spring which is supported with its free end on the actuating member.
- a compression spring which is supported with its free end on the actuating member.
- the housing extension of the actuator with the switching cam is provided between the two individual contact parts and the two housing walls, so as to move the two contact points against one another in the switched-on position and to ensure reliable contact.
- the two individual contact parts carry between them the shoulder on the actuating member which carries switching cams on the sides facing the contact parts.
- the contact parts cooperating with the switching cam have an expression at the contact point which forms the counter-projection on the contact part.
- the actuating element is optionally designed as a pivot actuating element and / or push actuating element and / or sliding actuating element and / or rotary actuating element, the cooperating contact parts being able to be moved into their open or closed position in the case of a linear or radial movement.

- the switch housing 3 1 has a receptacle 49 in which a compression spring 51 engages and is supported on the floor, while the second end of the spring is supported on a mandrel 50 of the actuating member 32.
- the glow lamp 45 is arranged in a chamber, above the glow lamp a magnifying glass 52 is provided in the actuating member in order to allow the glow of the glow lamp to radiate out of the actuating member if necessary.
- the mode of operation of the switch is now such that it switches from the off position in FIG. 1 when the actuating member is moved into the on position in FIG. 4.
- the two legs 38 are guided against each other so that their touch contacts 29 touch and there is a power short.
- the glow lamp receives the necessary voltage to light up via the connecting terminal 43 and the additional terminal 47.
- a spring 5 1 is provided between the actuator and the switch housing.
- the spring is almost relaxed in FIG. 1, so that this position is the preferred position of the switch, in other words the switch is switched off.
- the rocker-type actuator performs a pivoting movement, so that the state shown in FIG. 4 is reached and the switch is switched on.
- the actuator is released, the position shown in Fig. 1 is reached again.
- the two vertical legs 38 of the two individual contacts are parallel to each other but mirror images.

- FIG. 2 shows the arrangement of the individual contact parts 37 in FIG. 2.
- the switching cam presses the leg 38 away from the side wall via the counter projection 40 to the contact 39 of the other individual contact part, which also moves the leg 38 against the contact of the other contact part 37 when the switching projection is moved.
- FIGS. 9 to 13 is designed as a push button.
- the contact parts including the individual contact parts, the arrangement of the individual contact parts and the screwless terminal and the individual housing chambers are designed the same as in the first embodiment.
- the switching lug 33, 34 is arranged on a pressure actuating member 58. During the insertion movement of the switching lug 33, 34, it slides on the side walls 68, 69 of the switch housing until it abuts the counter-projection 40 and presses the leg 38 against the second leg 38.
- the switch housing has a horizontal guide in which a ball 59 slides, one half of which is in the guide of the switch housing and the other half of which is in a control cam 60. This allows the switch positions to be set.
- the control curve 60 is shown schematically in FIG. 13. This has a heart-shaped outline 61 and a kidney-like elevation 62 within the heart-shaped outline.
- the control cam 60 is arranged on the actuator.
- the ball 56 When the control member moves downward, the ball 56 abuts the kidney-like elevation 62 on the underside and then slides past the kidney-shaped elevation 62 to the side wall and from there to the upper part of the heart-shaped outline 61. From there, the ball slides again through the inclined position of the outline in the middle of the heart-shaped outline.
- the button When the button is released, the ball comes to rest on the top of the kidney-like elevation 62.
- the pressure actuator is actuated again, the ball hits the top of the heart-shaped turnover again. Due to the inclined surface there, the ball is moved sideways.
- the switch When the switch is released, the ball can then be moved laterally next to the kidney-like elevation until it is finally back in its original position, ie below the kidney-shaped elevation. The switch is in the off position in this position.
- the switch-on position results when the ball lies on the kidney-like elevation 62.
- the compression spring 51 always tries to push the actuator 58 out of the housing. This is prevented by the ball cam control.
- a glow lamp 45 is again provided, the connecting wires of which are led on the one hand to the pressure plate 56 of the screwless connecting terminal and on the other hand are contacted by a special screwless connecting terminal 47.
- a further contact part 36 is shown, which consists of two individual contact parts 63. It is in turn consists of a screwless connecting terminal, contact contacts 39, counter-projections 40.
- the contact part 63 see FIG. 15, is shown in an F-shape.
- the upper cross part 64 of the F carries the screwless connecting terminal 43.
- a first contact 39 is provided below it.
- the central cross member 65 carries the counter-projection 40.
- the individual contact carriers are formed in one piece and lie in one plane, with only the connecting terminals carrying bends which carry them out of the plane.
- the contact part 36 which is constructed from the two individual contact parts 63, which are rotationally symmetrical to one another.
- a single contact lies on one side wall 68, while the second individual contact lies on the lower wall 69.
- the switch cam 35 now moves against the counter projection 40, see FIG. 1 8
- the longitudinal webs 70 of the contact parts 63 are bent off by the screwless clamp until the contact contacts 39 touch.
- the two contacts 39 of the longitudinal web 70 of one contact part 63 touch the two contacts of the longitudinal web of the other contact part. So there is a double power transmission.
- the screwless clamp 43 has an extension 66 which engages in a slot 67 of the housing. In this embodiment, too, the screwless connection terminal lies in a chamber.
- the actuator is rocker-like. It is also loaded with a compression spring 51, so that this switch has a preferred position when the compression spring is present. As soon as it is moved in this preferred position, see FIG. 18, the individual contacts assume the position shown in FIG. 18.
- a pressure switch is constructed for the individual contact parts 63, which is moved via a cam control. The actuating member is in turn moved into its switched-off position by a spring, in which case the spring is supported on the one hand on a housing part and on the other hand on the actuating member.
- the individual contact part 63 is supported by the screwless connecting terminal in the switch housing and is pulled down to the floor with its longitudinal web, so that there is a large suspension.
- This switch housing also shows the same housing for the pressure switch and the rocker switch. However, the built-in compression spring 51 is arranged somewhat differently.
- the rocker switch is converted into a button by omitting the spring, while the pressure switch is converted into a button by omitting the ball.
- the illustrated embodiments are only examples of realizations of the invention. This is not limited to this, but many other changes and applications are still possible.
- the switch could also be designed as a slide switch instead of a rocker switch or pressure switch, in which case the switch cam would be guided against the opposite projection during the slide movement. It is important for the invention that it can be decided at the installation site whether the switch should be designed as a pressure switch or as a rocker switch and / or slide switch and / or rotary switch. Depending on the choice of the actuator, differently operable switching devices can be constructed with the same switch design.
