electrics question

So I have a new switch for my wipers, it is off a roverp6

it allows me to fit a 2 speed escort wiper motor and also an electric window washer

so I have sorted the terminals for the window washer

however the anglia has 3 wires connected to its single speed switch, a red one and a black one. Both appear live. It has a black and white earth wire . Why are there 2 live wires on this switch?

the new switch has 4 terminals, labelled 1 2 3 4

terminal 4 appeared to be the common one that when wires were connected to terminals 1 or three the switch worked and terminal 4 I could get a light to glow. So thats easy.

what is the 4th terminal for?

can I just jam one live wire on 1 and one on 4 and connect my earth to terminal 3 to get a single speed wiper with wash pump?

im too scared to blow it up
