First of all the simple question, i need to wire up a simple passing loop. I know about having the power supplied from the toe end of the point, and isolating the two central frog tracks of the point, but i cant remember how to go about wiring the tracks into the dpdt switch.
Which kind of switch do i need, On/On or On/Off/On? and do i need one with 3 pins on the bottom or with the 6 pins?
Do these switches need to be permantly weatherproofed inside a tuppaware box or inside a building of some sort?
Secondly, to power our tracks, we use two of these, http://www.maplin.co.uk/p/100w-slim-bench-power-supply-n93cx , one for each loop. These have always perfectly suited our needs, but the only trouble is that to change direction of travel, you have to switch over the 2 wires in the front of the power supply. Is there a way in which a similar dpdt switch could be wired in between the track and the transformer to allow polarity to be changed via a flick of the switch rather than swapping the wires over each time?
Would this switch need to be weather proofed at all times? (The power supplies come inside after each running session)
Would i need a special switch capable of handling the high amps or would a normal toggle switch be ok?
Any wiring diagrams for either problems would also be much appreciated!
Many thanks
Matt
