I have just bought one of these but I am not sure if it is faulty.
I have placed my multimeter connectors on each of the spades and have put the meter to test for continuity. I was expecting that when I pushed the little plastic head in, I would get continuity, but I don't.
I have also tried measuring resistance and again there is no change when it is pressed in/ released.
Am I missing something, or is that a sign of a faulty switch (it was in an old unipart bag).
