It needs to go with a 9v PP3 battery. Is there a suitable thyrister from Maplins? 106?

No relays. The only relays I saw on Maplins were rated at several hundred volts but obviously had small gate currents. I assume fine with 9v dc?

something like that, but idealy 9v coil rating you only need a single throw one for the circuit i just drew a 2 one for some reason.

with thyristor circuit you need resistors too that bump the price of buying 60units so could be about even for cost
