Rotary switch according to claim 16, characterized in that the conductive pattern is three Has annular areas (73, 75, 77 "from two of which are connected and the third (75) at one point through the V-shaped insulating surface (83) and is interrupted at another point by the second insulating surface (81).

19. Rotary switch according to claim 3, characterized in that the intersection of the legs the V-shaped insulating surface is arranged outside of the center point via the commutator disk is that by a lateral displacement of the commutator disc, the angle, about which the brushes (31) and the conductive pattern are in contact, greatly enlarged or reduced will.

The present invention relates to an adjustable rotary switch, preferably for mechanized Filing cabinets for storing files, keeping the files on an endless orbit can be moved, lfm generally have filing cabinets with surrounding containers Mechanism with an endless loop, e.g. B. a conveyor driven by a motor

Preferably the movement is vertical. The drive motor a rotary switch is assigned to which, if desired, a remote switch from the rest position to the access opening in the Bring the filing cabinet, which determines the direction of rotation of the motor. Since the container is in a conveyor with an endless loop, they can go in one direction or another Access opening can be moved.

From the preceding description it can be seen that a simple switchgear was created. Instead of one slice in relation to the other too move to adjust the holding position when a switch is in a mechanism in a filing cabinet is used with rotating containers, a simple adjustment by moving back or forth is sufficient Reciprocation of a commutator disc with respect to the brush holder. The device according to the present The invention can therefore be adjusted much more easily than known devices. About it In addition, the use of a single commutator disk instead of a pair of commutator disks as suggested in U.S. Patent 3,198,894, for example, is far more economical.

summary

The adjustable rotary switch described is suitable for use in a power-driven Filing cabinet, which is used to store files in separate groups, with the groups in can be moved in an endless path. The switch comprises a chain wheel, a commutator disk and a brush holder arranged around the axis of a bolt. Also is a guide block angle attached to the commutator disk and works together with a commutator block attached to the sprocket to achieve the

ίο Lateral position of the commutator disc in relation to to change the brush holder. On the commutator disc face opposite the brush holder there are different leading regions. These regions work with those in the burst holder mounted brushes together. Predetermined positions in the leading regions are given by a V-shaped, outwardly extending region of insulating material separated. The movement of the commutator disc with respect to the brush holder

ao the interaction of the guide block and the guide block bracket changes the length of time, which for a brush is needed to pass over the V-shaped isolating region or runout. In this way, the length of time during which

a5 more like a brush when stopping at the stop distance lingers, changed.
