Allgemeine Elektricitäts-Gesellschaft in Berlin *) Switches, especially toggle switches

Patented in the German Empire on August 8, 1931

Installation switches are already known which consist of a housing-like upper part that is open on the lower side and a lower part. Both parts carry some of the contact parts necessary for a complete switch of simple design and circuit and only together produce an operational switch.
The invention now relates to switches, in particular toggle switches, with a housing carrying the switching mechanism and the connection contacts, partially or completely open on the lower side, and aims to use such an upper part, which can be used as a simple on and off switch, for any other Types of connection, such as cross connection, series connection, changeover connection, etc., without having to make significant changes to the upper part.

According to the invention, an insulating floor is in the lower housing opening with it embedded cable bridges can be used, directly or indirectly with the switching element and the terminals come into contact and the latter to achieve further circuit possibilities besides the simple Switching on or off, for which the upper part of the housing alone is sufficient, in a suitable manner associate. The conductive connection between the terminals attached to the upper part of the housing and the cable bridges of the base is preferably done with the help of plug-in devices. The terminals of the upper part can be used as plug sockets for the connection with the cable bridges on the base be designed or carry connector pins. The base preferably consists of layered insulating material panels, between where the cable bridges are jammed. The cable bridges can have contact lugs be provided that protrude into the upper part and with the as a movable switching element serving contact role come in their end positions in conductive connection.

The drawing shows in Figs. 1 to 5 on a cross switch, for example, the invention, namely is

Use of the switch as an on and off switch has an approximately box-shaped shape and is open on the bottom side, while on the top side there is only one opening for passage of the operating lever is available.

The switch housing can be placed with its open side on a base η in such a way that it is guided in the housing. The base η consists of several sheets of insulating material lying on top of one another, between which the metal connections, for example O ₁ to O ₄ , which are necessary in accordance with the required circuit change, are accommodated. The individual plates are attached to a base plate n ' with the aid of rivets χ. The metal connections O ₁ to O ₄ end as required in contact lugs V ₁ to V ₄ , which protrude into the switch housing in such a way that they come into conductive connection with the switching pulley in their end positions. The connection of the metal rails O ₁ to O ₄ with the terminals T ₁ to r ₄ , of which only the terminals r _s and r _{4 are} visible, is done with the aid of a plug-in device, namely the metal rails carry connector pins W ₁ to W as required ₄ , which come into engagement with the terminals Y ₁ to r ₄ designed as plug sockets. Otherwise the terminals are not connected to one another. The base has recesses f for the switch mounting screws. Numerous other embodiments are possible. The terminals can also carry plug pins and engage in corresponding sockets in the base. The base can also consist of a single insulating piece, of pressed material or ceramic material into which the metal parts are pressed, cemented or screwed.

The invention makes it possible to achieve arious only by replacing the pad η T "circuits.

Instead of a toggle switch, another switching mechanism can also be used Find.

The whole thing can be packed in a housing for surface mounting or in a flush-mounted box with a cover.

Claims (5)

Claims; i. Switch, in particular toggle switch, with a housing carrying the switching mechanism and the switching and connection contacts, partially or completely open on the lower side, characterized in that an insulating base (n, n _± ) embedded in it in the lower housing opening. Cable bridges (O ₁ to O ₄ ) can be used, which directly or indirectly come into contact with the switching element (e) and the connection terminals (f) and the latter to achieve further circuit options besides simple switching on and off, for which the upper part of the housing alone is sufficient , connect in a suitable manner. 2. Switch according to claim 1, characterized in that the conductive connection between the terminals (f) attached to the upper part of the housing and the line bridges (O ₁ to O ₄ ) of the pad with the aid of plug-in devices (W ₁ to W ₄ ) takes place. 3. Switch according to claim 1 and 2, characterized in that the terminals (r) of the upper part designed as plug sockets for the connection with the cable bridges of the base or have connector pins. 4. Switch according to claim \ to 3, characterized in that the base consists of layered insulating material, between which the line bridges are clamped. 5. Switch according to claim 1 to 4, characterized in that the line bridges are provided with contact lugs (V ₁ to V ₄ ) which protrude into the upper part and come into conductive connection with the contact roller (s) in their end positions. 1 sheet of drawings
