IE, do you get the same reading as you would if you shorted the test prods together, indicating a dead short (needle of the meter full scale deflection to the RH side? If so, that indicates a dead short, and yes, you've wired the switch wrong. Or do you mean you get 'no reading' - IE, the needle doersn't move at all, in which case that isn't 'zero Ohms' but infitinty - an open circuit in other words.
I must have been tired last night when I was doing this! The Avo was a model 8 and it was reading at the LHS - which I assume to be infinity and not zero! Therefore, David you would be correct and this would be open circuitwith the switch in the off position and 200R when switched on. If so, have I still wired the switch incorrectly?

if all else fails...read the instructions!
