I didn't think that 3 pole on-off-on switches were very common, however, I have just found this one on Ebay https://www.ebay.co.uk/itm/On-Off-On-3PDT-Toggle-Switch-250V-AC-15A-3-Pole/283440763590?epid=12031320056&hash=item41fe62d2c6:g:VC8AAOSwXdpcpeEN#rwid
The same result can be achieved using one of these instead of a relay. Before doing so you would have to totally happy that the switch gives enough isolation between the mains and heater poles.
