IN our issue dated November 16, 1934, we described an electricalcontrol unit designed for A.E.C. oil and petrol-engined vehicles, the object of which was to localize all electricalcontrol components, thereby reducing considerably the wiring needed, affording better protection for the parts, and increasing the accessibility of items requiring periodic attention.
Since then a number of improvements has been effected in the device, two illustrations of which appear on this page. Its position is seen to be on the right of the driver, and the switches are so arranged as to be easily operated without his attention being 1380 distracted from driving. The central button, on which he has his right hand, dips the headlamp, one push bringing the anti-dazzle apparatus into action and the other returning the headlamps to normal. On the near-side front corner of the top is the 'horn push, which he can depress with ..his elbow. Also ou the top are grouped the lighting switches, etc.
Within the box, and adjacent to their respective switches, are the unit fuses and terminals. 'The interior connections are made by copper strips; riveted where practicable, and, where the main cables leave the box through an insulating duct, a cleat is pro-, vided. to relieve the terminals of all mechanical stress. The box is hinged at the bottom so that it can be swung forward to expose the rear connections.
An. important component of the equipment is a four-pole badttery master switch, which carries the full starter current. It is controlled by an exterior handle and completely isolates the battery when the switch is opened. For the heater solenoid, one double-pole unit replaces the two single-pole units previously used. The voltage regulator and dynamo cut-out are housed in a sealed container, and can readily be detached.
We understand that this control box, which has been specially designed for the Associated Equipment Co., Ltd., Southall, Middlesex, and is made by C.A.V.-Bosch, Ltd., Acton, London, W.3, and Simms Motor Units, Ltd...ie Grease Street, London, W.1, is to hi standardized on all A.E.C. goods and Passenger vehicles.
