voltek lighting

Is it possible to trigger a voltek lighting contoller with a simple push switch either PTM or PTB . The old and awful Racalite systems had this facility using a simple bell push
I know I can buy an accessory to activate the lights but its a lot of money for what is basicly a simple swiching operation

hi short R to - to activate lights.

Thanks Sparkymark
I agree your mod will work but that brings the light on permanantly
However I think I may have solved my own problem
If you interupt the signal wire momentarily you can trigger the light for its preset time on activataion Simples !
Now to fit it and see if it works on site , will report back later in the week
