<p>An electrical pressure indicator, particularly for motor vehicles, includes two movable contacts (4, 5) which are carried by a rotary arm (3) and both of which are in sliding contact with a comb-like formation (17) including conductive portions (18) alternating with insulating portions (19) and terminating in a deposit of resistive material (20), in order to provide a variable resistance directly proportional to the pressure detected. The radially inner movable contact (5) cooperates with a terminal conductive area (11) in order to indicate a predetermined anomalous pressure value. <IMAGE></p> |
