In Fig. 1 is a perspective view of a switch insert for a single switch / single button in the form of an exploded view. At execution for a single switch / single pushbutton, the switch insert 1 is composed of the following main components:

• a housing lower part 3 with a switching chamber (respectively with two switching chambers in a double-switch / double-button, see Fig. 10 )
• a rocker switch 10 for a single switch / single pushbutton,
• a transverse actuator 20 which is slidably mounted in the rocker switch 10,
• a housing top 28,
• a longitudinal actuator 33 for a single switch / single pushbutton.

The lower housing part 3 has on its underside or on its side surfaces two terminals 4, 5 (screw terminals or plug-in connections) for electrical lines. At its top, at least two pivot-engagements 8 are provided, which cooperate with pivot 13 of the rocker switch 10, whereby a pivotal movement of the rocker switch 10 within predetermined limits relative to the housing base 3 is made possible.

The rocker switch 10 has on its underside a switch plunger 14 which dips into the housing lower part 2 and there acts on a contact rocker 6, to effect such switching operations (ON-switching / OFF-switching, Tast-voltage pulse), as described in the FIGS. 6 to 9 is explained in more detail. At the top of the rocker switch 10 is at least one receiving space 16 for the transverse actuator 20th

The transverse actuator 20 has a first inclined surface 21, a second inclined surface 22, a first recess 23 and a second recess 24, wherein for further explanation of the operation of these embodiments on the FIGS. 6 to 9 is referenced. Of importance is also held within the transverse actuator 20 spring 26 which allows a resilient, translational movement of the transverse actuator 20 within the receiving space 16 of the rocker 10 and at rest, a return of the transverse actuator 20 in a central position (central position ) causes.

The upper housing part 28 can be latched to the lower housing part 3 via a plurality of latching means 29 and, in its upper region, has a guide 30 for guiding the longitudinal actuating member 33 which dips into the housing upper part 28. In this case, 33 springs 38 are inserted between spring receptacles 31 of the housing upper part 28 and the underside of the longitudinal actuator, which effect a resilient return of a pressed toward the housing lower part 2 longitudinal actuator 33 back into a rest position. In this case, locking means 39 provided on the lower side of the longitudinal actuating member 33 prevent the longitudinal actuating member 33 from sliding out / falling out of the guide 30 of the housing upper part 28. Of importance are two provided on the underside of the longitudinal actuating member 33, with the transverse Actuator 20 cooperating actuating arms 36, 37 (see also the FIGS. 6 to 9 ).

In Fig. 2 an electrical installation device 46 is shown in the form of a single-switch / single-button, consisting of the switch insert 1, which by a central disk 41, a centrally disposed within the central disk 41 and cooperating with the longitudinal actuator 33 hand operation button 42nd for single switch / single pushbutton and a cover frame 45 is completed.

In Fig. 3 For example, a switch insert for a single switch / single pushbutton is shown in which the lower housing part 3 is connected to the upper housing part 28. It is the springs and movable mounted in the switch insert 1 longitudinal actuator 33 to recognize.

In the FIGS. 4 and 5 are a view of one and a perspective view of a rocker switch for a single switch / single button shown. The rocker switch 10 has two receiving spaces 16, but in only one receiving space, a transverse actuator 20 springs and is movably guided / held. For the leadership / support of the transverse actuator 20 a plurality of guide / retaining ribs 17 are provided. For the fixation of the formed in the form of a coil spring spring 26 on the transverse actuator 20, the latter is provided with two opposing rod-shaped spring holders 25.

Within the receiving space 16 of the switching rocker spring stop surfaces 18 are arranged, between which the spring 26 can move. Once the transverse actuator 20 is deflected from its rest position - see the two possible lateral directions of movement indicative double arrow - the spring 26 is pressed against one of these spring stop surfaces 18 and the spring 26 is compressed. Consequently, the spring 26 has the tendency / task, the transverse actuator 20 always returned to its rest position, as soon as possible.

Essential components of the transverse actuator 20 are the two inclined surfaces 21, 22 and the two recesses 23, 24th

Furthermore, the show FIGS. 4, 5 the two required to pivot the rocker switch 10, engaging in trunnion engagement 8 pivot 13. In Fig. 5 Furthermore, the switch plunger 14 can be seen.

In the FIGS. 6, 7, 8, 9 Side sections are shown by a switch insert to explain the operation of the switch insert 1 on the basis of a switching operation. Fig. 6 shows as a starting position a through-connected (closed) switch, ie there is a closed circuit from the terminal 4 with its located in the switching chamber switching contact 4, which contacts the switching contact of the contact pad 6, further on the rocker bearing of the contact rocker 6 (rocker mount), which leads to connection 5. The rocker switch 10 is inclined to the left, consequently, the switch plunger 14 is right of the rocker bearing. It is indicated by means of a spring 15, that the switching plunger 14 is resiliently guided / locked within the switching rocker 10. The transverse actuator 20 is in its rest position in a central position in relation to the switching rocker 10, which is effected by the spring 26. It can be seen the two engaging in the spring 26 spring mounts 25 of the transverse actuator 20.

The spring-guided in the housing upper part 28 longitudinal actuator 33 is in its rest position with a relaxed spring 38. Consequently, the two actuating arms 36, 37 decoupled from the inclined surfaces 21, 22 and the recesses 23, 24 of the transverse actuator 20th

The switch should now be opened during the subsequent switching operation (OFF switching). For this purpose, 38 pressure against the spring force of the spring exerted on the longitudinal actuator 33 in an operating direction A to the housing lower part 3, which is done by pressing the manual operation knob 42. First, the in Fig. 7 shown configuration, in which the actuating arm 36 slides along the inclined surface 21, with the result that the transverse actuator 20 is deflected in relation to the rocker switch 10 to the left - see arrow B. At the same time, the pressed against the spring stop surface 18 Spring 26 compressed.

Furthermore, pressure is exerted against the spring force of the spring 38 on the longitudinal actuator 33 in the direction of actuation A to the housing lower part 3 out. Consequently, the spring 38 is further compressed and the actuating arm 37 now engages in the recess 24, as in Fig. 8 is shown. Triggered by the actuating arm 36 located at the base of the inclined surface 21, a rotational movement of the rocker switch 10 results around its axis of rotation (pivot 13 / pivot engagements 8), ie the rocker switch 10 tilts to the right (clockwise), as indicated by arrow C.

As a result, the switch plunger 14 slides to the left beyond the rocker bearing, whereby the contact rocker 6 performs a rotational movement to the left (counterclockwise), which for opening the switching contact, d. H. Lifting the contact rocker 6 from the switch contact 7 leads. The transverse actuator 20 remains in its deflected to the left position, blocked by the engaging in the recess 24 actuating arm 37. The circuit from terminal 4 via the contact pad 6 to 5 port is now interrupted.

After no more pressure is exerted on the longitudinal actuator 33, the in Fig. 9 shown rest position with now open switch contact, in which the spring 38 relaxes and thereby the longitudinal actuator 33 pushes up - see arrow D - and in which also the spring 26th relaxed, causing the transverse actuator 20 moves in relation to the rocker switch 10 to the right in a middle position - see arrow E. The resiliently guided in the housing top 28 longitudinal actuator 33 is then back in its rest position with a relaxed spring 38th Consequently are the two actuating arms 36, 37 in turn decoupled from the inclined surfaces 21, 22 and the recesses 23, 24 of the transverse actuator 20th

As soon as pressure is exerted against the spring force of the spring 38 on the longitudinal actuator 33 in an actuating direction A to the housing lower part 3, the switch is closed at the next switching operation (ON-switching).

• das Gehäuse-Unterteil 3 weist zwei Schaltkammern mit separaten Kontaktwippen 6 und die erforderlichen Anschlüsse für elektrische Leitungen auf,
• das Gehäuse-Unterteil 3 weist insgesamt vier Drehachsen-Eingriffe 8 für die Lagerung von zwei separaten Schaltwippen 11, 12 auf,
• jede Schaltwippe 11, 12 ist mit einem separaten Quer-Betätigungsglied 20 inklusive Feder 26 ausgerüstet,
• im Gehäuse-Oberteil 28 sind zwei separate Längs-Betätigungsglieder 34, 35 geführt.

In Fig. 10 is a perspective view of a switch insert for a double switch / double button in the form of an exploded view. Compared to the single switch / single button, the following changes result:

• the lower housing part 3 has two switching chambers with separate contact paddles 6 and the necessary connections for electrical lines,
• the lower housing part 3 has a total of four axes of rotation interventions 8 for the storage of two separate shift paddles 11, 12,
• each rocker 11, 12 is equipped with a separate transverse actuator 20 including spring 26,
• in the housing upper part 28, two separate longitudinal actuators 34, 35 are guided.

In Fig. 11 an electrical installation device 47 is shown in the form of a double-switch / double-button, consisting of the switch insert 1, which by a central disk 41, two arranged within the central disk 41 and with the longitudinal actuators 34, 35 cooperating manual operation knobs 43, 44 for double switch / double push button and a cover 45 is completed.

In Fig. 12 a switch insert for a double-switch / double-push button is shown, in which the housing lower part 3 is connected to the housing upper part 28 is. There are two spring-mounted and movable mounted in the switch insert 1 longitudinal actuators 34, 35 can be seen.

In the FIGS. 13 and 14 are a view of the two and a perspective view of both paddles for a double-switch / double-button shown. Each of the two shift paddles 11, 12 has a receiving space 16, in each of which a transverse actuator 20 springs and is movably guided / held. For the leadership / support of the transverse actuators 20 each have a plurality of guide / retaining ribs 17 are provided. For the fixation of the formed in the form of a coil spring springs 26 on each transverse actuator 20 latter are each provided with two opposing rod-shaped spring holders 25. For the independent pivoting movement, each switching rocker 11, 12 has two pivot pins 13.

In the above explanations on the operation of a bistable switching device is assumed, ie the contact rocker 6 is able to take two stable switching positions, so as to enable a permanent ON / OFF switching. In an alternative development beyond a usable as a pushbutton monostable switching device in the same manner can be realized, ie in this embodiment, the contact rocker 6 springs after being acted upon by the longitudinal actuator 33 always back to its rest position, which z. B. the position "OFF-switching" corresponds. The "ON" position is always taken only for a short period of time during the actuation of the longitudinal actuator 33 so as to effect a strobe voltage pulse. In such an embodiment, the transverse actuator 20 need only have an inclined surface 21 and only one recess 24. However, the transverse actuator 20 required for the bistable switching device can also be used in the monostable switching device (push button), which advantageously results in a reduction of the required structural components.
