Rotary resistor with contact set for additional switching purposes.

The firing refers to a rotary resistance, e.g. a potentiometer, "by means of whose rotary axis a contact set" is to be actuated for additional switching purposes, as is often the case, for example, in communication devices, in addition to a control made by setting the "rotary resistance BS:" are additionally desired. The axis of rotation has a greater length for the actuation of such a contact set than would be required for the adjustment of the rotation resistance alone. To enable the contact set is, according to the renewal, on the; - "'axiseine'Mtnähmeeinrichtung pre associate,' in which, that of • ■ an insulating material disk .getragene additional Kontaktsatz- ■ ■ -:.... ^ Uer 'pushed axially' for is -To is at entapre- ■ - chender- training 'of the' turning resistance 'the / possibility given,

to install a contact set for additional switching purposes in a simple way. ¹ Depending on the arrangement of the "ederri" of such a contact set, the contact set can then continue to be used for switching on and off and / or switching over. _.
