6 FLIGHT 19 FEBRUARY 1954 VENNER TIME-DELAY SWITCH (Type TDS/359) is used extensively in lead ing British Military Aircraft with fully feathering propellers. This switch is specially designed for use in aircraft fire extinguisher systems to delay discharge of the main methyl-bromide spray until the engine has come to rest. It can also be adapted to disconnect the batteries within a specific period of time in the event of a crash. VENNER AIRCRAFT EQUIPMENT JJlIFf) Write for full particulars to Dept. F.

It is unaffected by changes of voltage and frequency met within the normal aircraft supply. The control, however, being an inching control, is selected to control about a point within the control band, when, under stable conditions the temperature of the sensing element will be held within the differential of the system. It consists of four units; the Magnetic Amplifier Control Unit, the Sensing Element, the Temperature Selector, and the Follow-up Resistor, the latter being mechanically linked to the temperature control valve.
