RGB LED Help

[g4m8l3r]

Hi Guys

new to this forum so be nice please

Basically I have 3 RGB LED strips in my kitchen controlled by a basic RGB controller (2x2m 1x 0.6m), the 0.6m length I would like to have a switch to bridge the 3 RGB pins together to create white whilst the other 2 strips are still controlled by the RGB Controller, then it can be switched back to RGB mode when required.

I have currently put in place a 4pole double throw toggle switch which bridges the required connections however when I switch it to white mode it puts all the strips in white mode instead of just the 0.6m.

The strips are linked to the controller all at one point instead of one after another.

Help on this would be brilliant, thanks in advance.

Assuming it's DC, diodes could be used with your switch to prevent the 'back feeding'. Or buy a second controller.

yes it is, il have to pick some diodes up from maplin, its the only place near me.

don't suppose you could recommend one could you?

What current and voltage are we talking about?
Am thinking a 1N4001 which is a 1A silicon rectifier diode (50v forward, 35v reverse voltage) but you'll have to check the specs.
