Yes, that is what I do if I want more contacts. I found you can get a relay board off that popular auction website, for less than I can buy the relay for. Admitadly, it comes from China, so you have to wait a bit, but they are well made. Someone in the UK sells one that is quite reasonable as well. I tried the Seep points, but found that they were a pain to set up. I like the Peco PL10 as you check the motor with the point, before you fit it, the only issue is you have to cut that big hole in the baseboard, but if you buy the covers, then that is not a big issue. The advantage, is if the point breaks you can remove the point motor and switch in one go. The other thing is I hate slider switches, they are always suspect on reliabilty. The Seep ones are better than the Peco PL13, as they are part of the point.
