Variable electric resistor for road vehicles - has rotary spindle with cursor moving on wafer track
Abstract
Abstract The variable electric resistor has a simple construction and is dust-proof and resistant to vibrations for use in road vehicles. It has a plastic material case (1) with a threaded boss (2). The threaded boss (2) has a central hole to take a plastic material spindle (3) onto which is mounted a cursor and a pivot. The cursor makes contact with an electrically conductive wafer track to provide a variable resistance by rotation of the spindle and the cursor. The cursor is electrically connected to the pivot and the track is connected to two terminals. Connection to the cursor is by means of a terminal (5) integral with a disc in contact with the pivot of the spindle.
