erfolgen soll, ausgestanzte öffnungen besitzt, in welche die Kontaktarmnocken eintreten können. Auf diese Weise ist es möglich, ohne Änderung des Preßwerkzeuges für die Nockenscheibe 4 eine den jeweiligen Schaltfolgen der Zusatzkontakte entsprechende Kontaktgabe durch einfaches Ausstanzen der erforderlichen öffnungen an der Steuerscheibe 13 zu erreichen. Eine Verzahnung der Steuerscheibe 13 gegen den Sperrwerkshals 7 verhindert die Verdrehung der Steuerscheibe gegenüber der Nockenscheibe 4.is to take place, has punched openings in which the contact arm cams can enter. In this way it is possible without changing the pressing tool for the cam disk 4 a contact corresponding to the respective switching sequences of the additional contacts to be achieved by simply punching out the required openings on the control disk 13. A toothing of the control disk 13 against the locking mechanism neck 7 prevents the rotation of the Control disk opposite the cam disk 4.

Bei der Montage eines Schalters ohne Zusatzschalter wird der Kontaktträger 9 mit den Kontaktarmen 10 und den Anschlußklemmen 11 fortgelassen. Bei der Ausführung des gleichen Schalters mit Zusatzschalter wird der Kontaktträger 9 mit Kontaktarmen 10 und Anschlußklemmen 11 in den freien Raum eingesetzt, nachdem die Nockenscheibe 4 mit der Steuerscheibe 13 bestückt ist. Am Blechgehäuse 3 angebrachte Laschen greifen dabei in die Nuten 12 des Kontaktträgers 9 und halten diesen verdrehungssicher in seiner Lage.When installing a switch without an additional switch, the contact carrier 9 with the contact arms 10 and the terminals 11 are omitted. When the same switch is designed with an additional switch the contact carrier 9 with contact arms 10 and terminals 11 is used in the free space, after the cam disk 4 is equipped with the control disk 13. Attached to the sheet metal housing 3 Tabs engage in the grooves 12 of the contact carrier 9 and hold it against rotation in its location.

Claims

The invention relates to an additional switch for device switches with axially acting contact arms, which is attached to switch on signal lamps or for locking purposes. There are Known switches in which such a device as an additional switch on the front or back, with the Mechanically coupled switch axis is used. Likewise, this additional device can be used as a fixed Be part of the switch. In all cases, however, these additional contacts increase the Dimensions and the installation space of the switch mostly in the axial direction.

According to the invention, the attachment of an additional switch without enlarging the switch achieved in that the contact carrier of the additional switch receiving a latching device Enclosing the neck of a cam disc. The space between the cam disk is used and the front panel is present.

The drawing shows an example of the subject matter of the invention. It shows

Figure 1 is a view of the additional switch from below,

Figure 2 shows a section through the entire switch in the middle plane.

The switch shown consists of a U-shaped sheet metal housing Z, which accommodates all other switch parts. On the front of the housing there are trough-shaped recesses 2, into which the compression-spring-loaded balls 1 engage when the switch is actuated. The balls are guided into bores in the locking mechanism neck 7, which is part of the cam disk 4. On its underside, the cam disk carries the cam tracks 5 for actuating the main contacts, which are arranged in the contact carrier 8.

The contact carrier 9 of the additional switch carries the contact arms 10 and the connecting terminals 11. One of these contact arms, which is intended for signaling purposes, is actuated in the radial direction by the switching cam 6 a. The cam arm or arms for control or locking tasks are actuated in the axial direction by concentric cam tracks 6?) On the upper side of the cam disk 4. According to the invention, it is further proposed that the axially acting cam tracks 6 b be formed by a punched-out, replaceable control disk 13 that is known per se, in accordance with the respective requirements. In this case, circular grooves are left in the cam disk and these are covered with a hard paper disk designed as a control disk 13 which, at the points where a circuit has additional switches for device switches
with axially operated contacts
