DE1060459B - Push button with lighting - Google Patents

Description

GERMAN

The invention relates to a push button for telecommunication purposes with lighting, in which the The lamp and the label can be easily changed from the view of the device, z. B. when used as a control current button for communications, in remote control, counter and Intercom systems, radio receivers and bell pushers including light call systems.

With the known pushbuttons in communications engineering, one or more signal lamps must be used can be assigned to a key or to a key strip. Among the most used Lamp sockets are used with covers in different colored designs. Illuminated buttons included a lamp. The replacement is done by pulling off the hollow shaft-like button with a lamp puller performed. Illuminated pushbuttons are also designed so that they can be removed without tools the button a lamp or the label can be changed. Lights and Here, too, the version remains fixed in the structure of the pushbutton. In the case of a control acknowledgment switch, proposed that the lamp is arranged interchangeably in the movable actuating part. To change A removable part is released from the lamp. The plug-in socket is fixed to the actuating part tied together.

The known bell pushers have versions for buttons and signs on a base plate, as well as bell pushers with nameplates as a uniform component, where on one side of the Shield, the button is mounted in a hinge or is guided in the front panel or in the housing. In In the illuminated versions, the nameplates are made of translucent material, whereby the The lights and, in some cases, the label have to be replaced from behind. The demand by the The construction of new residential buildings shows the need for illuminated name plates for door intercoms. At the moment the task has also been solved in such a way that a clear and frosted glass pane behind the tableau is mounted. These cover the vertical cut-outs. The lighting takes place common for all parts or also through reflectors on each row of handles. In summary, the in Experience brought the following disadvantages:

For communications technology, several components must be arranged for a signal path, to be able to replace the signal lamps from the front. In the case of pushbuttons, it is not advisable to to arrange a removable part with a lamp separately in the button where the socket is located. In the case of entrance panels with illuminated pushbuttons, the designation pushbuttons can be removed by loosening screws with lighting

nameplates and lights can only be replaced from behind. Replacing the parts is unfavorable for laypeople. These arrive at bell pushers, the buttons of which are guided on one side in the joint the installation that becomes free, whereby wires can break off. Push-button contacts with parallel guidance, the contact buttons of which are inserted into the front panel from behind, fall out of theirs when they are released Leadership, because the resilient contact device remains in the housing. At the door intercoms was the construction determined by the fact that the panel had to be designed as a lockable door in order to to be able to replace the labeling plates and lamps from behind.

In most cases, bulbs have to be replaced more often. Therefore arose from the existing Deficiencies in the task of developing a simplified pushbutton with a sign and lighting, with one or more lights and the label from the view of the panel, to better handling, easily replaceable.

According to the invention, the advantages of the push button for telecommunication purposes with lighting are now below Preservation of the advantage of the smaller dimensions, the simplified structure, achieved in that the Label with one or more lights and its contact springs on the socket in the button forms a structural unit and from the front, i.e. the view of the panel, by pulling out the button can be exchanged.

Claims (2)

In the drawing (Fig. 1 to 7) an embodiment of the invention of a push button with lighting for a bell button is shown: Fig. 1 shows a front view, Fig. 2 is a side view of Fig. I, Fig. 3 is a rear view of Fig. 1 Fig. 4 is a sectional plan view, Fig. 5 is a plan view of the tool, Fig. 6 is a circuit diagram, Fig. 7 is a view of the spacer bolt. The pushbutton switch consists of a plastic housing Ij which is used to accommodate the button 2. The flange of the housing has two through holes on both narrow sides to enable it to be attached to a front panel. In Fig. 3 three 1S piece connection terminals 3 can be seen. Below these are the contact springs 4 and 12, which are fastened with the screws 5 at the same time. Furthermore, a leaf spring 6 is located above each contact spring in order to increase the spring force. In the rest and working position, the leaf springs 7 come into contact via the contact springs 4. These give the festoon lamp 8 support and electrical connection via brackets 7a. The tubular rivets 9 connect the leaf springs 7 to the button 2, which bring the pressed button 2 back into the rest position through the contact spring 4 and leaf spring 6. At the head of the button 2 there is the transparent cover plate 10 with the label 11 made of milk glass or celluloid behind it. By pressing button 2, the working position for closing the rearwardly bent contact spring 12 is reached in such a way that leaf spring 7 establishes a connection from contact spring 4 to contact spring 12 and thus closes the circuit between terminals a and b. The tool 13 is required in order to enable the festoon lamp 8 or the label 11 to be exchanged. The jaws of this auxiliary tool grip key 2 at points X, whereby the leaf springs 7 yield in the direction of the arrow Y by pulling firmly and unlock the key. In the pulled out state, the festoon lamp 8 can be easily unhooked. The label 11 is pushed out to the side by removing the rubber wedge 14. The key 2 is inserted into the housing 1 by pressing on the cover plate 10, the leaf springs 7 again engaging in the housing. If the pushbutton is also to be used without lighting, a plastic pin 15 is hung in place of the festoon lamp 8 in order not to weaken the spring force of the leaf springs 7 that snap into place. Terminal c is then not connected during installation. PATENT APPLICATIONS: 1. Push button with lighting, characterized in that the label (11) with one or more lamps (8) and its contact springs (7) in the button (2) forms a structural unit and the contact springs (7) lock the button ( 2) in the housing (1) . 2. Push button according to claim 1, characterized in that its electrical connections are achieved by further contact springs (4) which can simultaneously take over the suspension of the button (2). 1 sheet of drawings © 909 559/307 6.59
