You'd need a five pin plug for a three way mid position valve though.

So when I need to replace, I connect a spare plug to the incoming device in advance. This avoids trying to wire something awkwardly and deep in the cylinder cupboard or wherever.

I didn't spend a lot of time investigating whether there might have been a more physical reason why the lever had broken. Was something mechanically jammed? Who cared? It was a cheap enough matter (£70, from memory) to replace the whole shebang. These days, Draytons allow you to replace just the head unit, not the brass bits. Which would have been even cheaper, and about an hour quicker.
