WW2 Switch, No.5, Pressure.

An example of a British WW2 Switch, No.5, Pressure. Designed to be operated when a pressure of 50lbs was applied to either the adjustable extension rod or the top plate of the switch. Often used against railways where the switch could be concealed under the rail and the rod adjusted until contact was made with the underside of the rail. Whilst not as positive as the fog signal igniter in this situation it had the benefit of being concealed in the ballast and thus avoiding detection. Excellent condition.
