Reed Switches - Use Of Reed switches in WTC

[jutland67]

Hi guys, I would like to ask your advice on putting a Reed switch (hope that is the correct spelling ! ) into the OTW Trafalgar class sub I am building. It is equipped with Bob Dimmacks excellent WTC which runs on a 12 Volt system. Is it possible to use a Reed switch to turn the power on and off without having to open the WTC everytime ? If so, what sort of switches would you recommend, as I was told that the small one I bought at Radio shack was more suited to switching a lamp on and off, than the system in my boat.....any and all advice would be much appreciated.

Nice circuit - should work

Nice circuit - should work well.

On the simpler side, if you have a flat surface on the WTC you could use a standard toggle switch (which will easily handle the current you're going to draw, unlike a standalone reed switch) with a waterproof hood. This just requires a small hole in the WTC, around which I run a small bead of silicon on both sides before screwing in the switch & fastening nuts. I then fill the head of the waterproof hood with vaseline (petroleum jelly) and screw it down onto the WTC over the switch. Works nicely on several subs

thanks for the advice guys,

thanks for the advice guys, I am still keen on using a Reed switch..the circuit is great but can you suggest a particular type or capacity of switch as i am pretty clueless about electronics.

Just had my electronics-savvy buddy

Just had my electronics-savvy buddy check out the diagram, and he says its a great and simple circuit.which he will knock up for me..just wanted to say thanks to Bradv and Himszy for your advice..this really is a great forum !
