So far I've tried several types of point motor on the railway:

The majority are the "Seep" PM-1 type: a solenoid point motor on a PCB with a built in switch. Generally these have worked OK but I have had a few issues. One motor just fell apart, and had to be replaced. Soldering the wires to the PCB has been a problem: I don't like permanently wired connections and tried to put "push on" terminals onto the PCB. Unfortunately that's too brutal for the PCB tracks. The next version was to drill holes and have the PCB laminate help out with the mechanical integrity, which has been better. In future I will probably use trailing wires and crimp "bullet" connectors on the wires. I've also had a problem with the PCB switches sometimes not making contact. This has been cleared with a squirt of switch cleaner. It could have been caused by flux from the soldering process.

In the Clanfield area I used Tortoise motors. These are well known and very reliable. They have a two pole switch which can switch frog power. There's a lot of misinformation about the rating of the switch contacts. They won't reliably break a 5A current: but that would only happen if you change the point while a 5A fault is flowing through it. If your booster shuts down when there's a track short (use a coin test) then this isn't an issue. They are quite bulky.

I have a couple of places that are quite restricted. In one of these I had a Peco solenoid motor with a long pin up through the baseboard, and a micro-switch on the motor body. This arrangement I've found to be unreliable: sometimes it will just stick. I've given up and removed them. I think if you didn't have the switch, or didn't have a long pin extending through 15mm of baseboard and cork, it would be fine. It's the combination of the two that causes the problem.

In one of those restricted places I've used a "Cobalt" motor. These are similar in idea to a Tortoise, but smaller. The DAC20 drives it fine. One difference is you can't move the output by pushing it across by hand.

I've purchased, but not yet tried, a batch of "Conrad" motors. These are powered constantly but have a limit switch. The DAC20 needs an output adapter to drive them.
