Thanks Mayner. I have heard the switch on seep pm1 motors is not fully reliable, which is a problem. I like your blue point motors, seem nice and reliable but I'm aiming for remote control. I have thought of tortoise but was hoping to avoid the cost. Having said that I might only need a small number of them , just for the 'backwards' power routed points .
I suppose I could use micro switches manually connected to the rod of the seep motor to switch the relay. Like the photo you posted for me in answer to a previous question of mine (which I've only now figured out what you meant!)
