(72) Klaus Maekler, SchalksmGhle, Federal Republic of Germany-Förbundsrepubl iken Tyskland (DE) (74) Leitzinger Oy (54) Electric operating switch - Elektrisk driftskoppling

The invention relates to an electric operating switch with or without a lamp for use in particular in steplight time switches, bell buttons or the like, in which a fixed and actuator-operated movable switch is arranged in the insulating material housing for short-circuiting the circuit, e.g.

To operate step light timers, bell switches, and the like, contacts have often been used with an oblique lever actuator, the more protruding part of which must be pressed by the user, so that finding this contact point is difficult, especially for small actuators. In addition, the operating path of these operating elements, whether small or large, is relatively long, so that the height of the device is adapted so that the size of the device becomes unfavorable. In addition, a certain amount of unnecessary force is required to operate such a lever actuator.

DE-OS 23 34 241 discloses a device of its kind with a lever actuator in a combination device of a current pulse switch and an electrical contact switch. In addition to the lever drive member, this device also has a movable clutch member formed as a toggle switch, the latter being arranged in a high bearing switch and operated by a spring-loaded pusher, thereby creating friction which makes operation difficult.

Another known device, namely according to DE-GM 18 74 563, uses a pushbutton contact as a contact sensor for moving the electromagnet. The pushbutton contact is known to require strong pressing and is unfavorably high in terms of installation, especially for appearance reasons.

The object of the invention is to provide an operating switch of the kind already mentioned, which has a contact device which causes the switching device to operate only lightly when touching an arbitrary part of a larger actuator, whereby the operating switch only needs to be very low and "short-stroke". In addition, the contact may still be equipped with a small lamp.

According to the invention, the task is solved in such a way that, starting from such an electrical drive switch, one of the two fixed contacts and the movable switch contact are formed annularly, whereby both fixed contacts are arranged on the base plate as well as the annular contact. These are concentric and have an opening in the center to receive a small lamn. The movable switch contact is on the one hand detached from the base plate and on the other hand rests on the lower edge of the flat housing cover forming the operating contact, which is connected to the base plate for immediate movement on all sides.

Furthermore, according to the invention, the fixed ring contact comprises two contact strips directed towards the apertures, which act as contacts of the small lamp. The opening itself has a collar which is surrounded by a fixed ring contact and which is cut off by the contact strips and which also acts as a guide for the movable clutch contact.

Furthermore, both fixed contacts are connected with contact pins in one piece to the electrical connection with the auxiliary device.

Furthermore, according to the invention, the annular self-elastic clutch contact rests on the collar of the drive contact on the one hand and on the base plate on the other hand with flexible legs slightly bent from the clutch ring, whereby one foot is in permanent contact with the other fixed contact. The movable clutch contact may be provided with contact rivets to provide contact to the fixed ring contact.

The drive contact has as connecting members at least three resilient projections which pass through the base plate and engage behind it with retaining handles to prevent unintentional release. In addition, the operating contact has a pulled-down circumferential edge which loosely surrounds the base plate. Besides, it has a window for detecting the light of a small lamp.

Finally, according to the invention, the small lamp is shaped so that the glass dome of the lamp is in a circular insulating part and its connection contacts are pulled to the side so that when the lamp is mounted on the base plate one switch contact optionally contacts one of the two fixed ring contact strips and the other switch contact contacts the other.

The object of the invention is presented as one embodiment in the accompanying drawings, in which:

Fig. 1 shows a sectional view of the operating switch with the attached accessories.

Figure 2 shows the base plate of the operating switch from above.

Fig. 3 shows the cover formed as the operating contact of the switch housing from below.

Figure 4 shows a top view of a base plate with movable switch contacts mounted thereon.

Figure 6 shows a separate lamp with its housings.

Figure 7 shows the movable switch contact separately.

Figure 8 shows a vertical section of Figure 1.

The drive switch consists of a drive contact 1, which simultaneously forms a housing cover and a base plate 2 movably connected to the drive contact 1 via projections 3 formed therein. In this case, the projections 3 pass through the holes 2a in the base plate 2 and engage behind the base plate by means of barbs 3a so that these two parts cannot detach themselves. As can be seen in particular from Figures 3 and 5, the projections are grooved in the longitudinal direction at three points, resulting in three longitudinally curved strips 3b attached only to the operating contact, which are spring-loaded and facilitate pressing the projections through holes 2a in the base plate.

The base plate 2 made of insulating material has a collar 2c protruding around the opening 2f, around which a fixed ring contact 4 is arranged and which at the same time has a pin 9 piercing the plate 2 in the hole 2b, whereby the ring contact 4 is fixed. The fixed annular contact 4 passes through the collar 2c by two contact strips 4b ', 4b "which optionally contact one switch contact of the lamp 5, 6. Thus, one contact strip 4b' is, for example, configured to provide contact for illuminating a device dependent on e.g. relay current; another contact strip 4b" is used lighting that is independent of the relay current, for example. The contact strips 4b ', 4b "thus optionally provide a contact to the switch contact 5a of the lamp 5, which is arranged in a housing similar to the insulator unit 6. The second lamp switch contact 5b is in the adhesive projection 6a, which is still optionally on the base plate 2. according to the installation in contact with the contact and connection pins 7 and 8. By means of this projection 6a the lamp device is simultaneously fixed in position on the base plate 2 so that the projection comes into contact with one of the contact pins 7 or 8, so that the lamp housing 6 cannot be rotated. and 10 pass through the pony plate 2, wherein the contact pin 9 communicates with the ring contact 4, and the contact pin 8 acts as a fixed counter contact.

As shown in Fig. 1, the contact pins 7, 8, 9 and 10 are each inserted into the contact terminals 12 of the accessory connected to the operating switch, where they are pressed between the compression spring 12b and the contact plate 12a. Terminals 12 simultaneously act as receivers for the connecting leads. In addition, there is still a purely mechanical connection between the operating switch and the accessory 13 by means of two pins 2d formed in the base plate, which press-fit to the housing or other part of the accessory 13. The accessory 13 can be mounted in a standard distribution box (e.g. 58 0), to which any other normal mountable device can be attached, for example with spreaders 14.

In addition to the holding lugs 3, the housing cover, which is formed as a drive contact 1, has a collar 1a on which the annular switch contact 15 is further supported. The clutch contact 15 is thus detached between the collar 1a and the fixed ring contact 4. In the neutral position, the switch contact 15 does not contact the annular contact 4, as shown in particular in Figures 1 and 8, because the three legs 15a, 15b and 15c protruding from the annular clutch contact 15 are slightly bent and resiliently rest mainly on the base plate 2. Further the contact leg 15c is in permanent contact 8, while the other two legs 15a and 15b rest only on the insulating material of the base plate and from this the leg 15b is attached to the abutments 2e of the base plate. Centrally on top of the lamp 5, the operating contact 1 has a window Ib for dissipating the lamp light.

Only when used, i.e. when the operating contact 1 is pressed, the flexible legs 15a, 15b and 15c give up so that the ring part of the movable contact 15 settles on the ring of the fixed contact 4 and comes into contact with it. When the operating contact 1 is released, the resilient legs 15a, 15b and 15c push the operating contact back to its initial position, whereby the annular part of the contact 15 is released again.

Figure 4 further shows how the movable switch contact 15 is arranged on a fixed ring contact. It can also be seen from Figures 1 and 8 that the movable switch contact 15 is simultaneously directed to the collar 2c of the base plate 2.

According to this device, it is possible to provide a contact member 1 which moves in all directions, i.e. that the largest possible surface area can be touched in each optional position, whereby a contact follows.
