3 pole or 4 pole (3P+N) switch

Hello All

I have a three phase supply coming in plus Neutral plus Earth. I'd like to wire two switches. Is there any reason I'd need to switch the Neutral (by using a 4 pole switch)? Or can I just use a 3 pole switch and let the N and E wires flow through continuous?

Thanks for any advice, kkc.
