Abstract

In a potentiometer, wherein switching functions are triggered in association with the potentiometer position electrical switches (21-24) are mounted on the potentiometer plate (1) which supports the collector path (11) for the purpose of the very accurate association of the switching operations with respect to the potentiometer position and with spatially fixed switch on and switch off points with respect to the collector path (11). The switch elements which effect the switching on and off are mounted ona potentiometer setting member (17) electrically insulated which supports the customary potentiometer slider (19,20). Advantageously, each switch (21-24) is formed by a contact path (25-28) and a contact finger (29,30) rotating and sliding over the associated contact path (25,28), whereby the contact finger is mechanically connected with the potentiometer member (17). The beginning and the end of the contact paths (25-28) define the switching on and off point of each switch (21-24) (FIG. 1).
