Reversing switch?

[Slats]

I know subtech use to make a good reversing switch -does anyone now make something like this?

They still do- http://www.subtech.uk.com/acatalog/S...ectronics.html

Also this one (relay based)

Seen these Andy but
Which one can be used as a reversing switch?

Well there is only one switcher on that page- the SES-3, fifth gadget down.

Andy,
I have got one of these SES-3s - had no idea it could be a reversing switch.
for an electrical dumb ass like me how do I rig this up to reverse a simple pump motor - so its forward one way - reverse the other?

I.e. only have the positive and neg wires from the motor - I just don't know how to reverse it through the switch? Got a diagram?

Thanks

Ahhh, no sorry. I thought you wanted to switch a couple of separate functions. I don't think the SES will work for you when running it through a motor. You need a controller set-up as an H-bridge for something like this.

There are switchers on the market that do this, e.g.

http://www.action-electronics.co.uk/pdfs/P44A.pdf

But they're cumbersome IMO.

I would just use a small reversible ESC, that way you also have proportional speed control of your pump. It'll almost certainly be cheaper than a switcher too.

What's it for, a submarine ballast system?

[Slats]

Thought about ESC but this is a pump solenoid combo. The solenoid needs atleast 6v to operate properly. The ESC giving proportional control wont activate it properly....so it looks like a couple of Microswitches and a servo then?

You just need to make sure the control is fully over. A solenoid will normally latch in well before full voltage rating anyway.

Just try it out with a spare ESC, I think you'll find it works just fine.

I'd get the Dimension Engineering Double Switch (double SPDT relays) and wire it as an H-bridge.

Another solution- you could use the esc, with a Y-lead from the RX and use this to control a servo with some microswitches, the latter just operating the solenoid. I take it the solenoid has to activate both ways?

[Slats]

I'll give it ago.

Andy re the ESC - can this be linked to a Fail safe too?
I'd rather ask than screw up some electronics trying.
Thanks

Yes of course you can.


Another switcher I completely forgot to mention is Norberts ballast tank switch. this is custom made for the job, with a built in failsafe and undervoltage monitor-

Plug and play.

Mike has them, Under product code SUB ES2 on the Switches and Solenoids Page (http://caswellplating.com/models/bhm.html) costs US$39.00. I have one of these myself and it seems to work alright although I have not loaded it up yet
