Bandit k5 1200 on off switch wiring to headlight help

[Tommy136]

 looking for major help I brought a k5 bandit 12 and it had the standard single headlight on it I have removed that and put a twin headlight on all working however I didn’t like how it comes on permenant the low beam and side light so brought a on off switch to wire into it and I’m not sure what wires I mess with but figured it was the white wire coming from my wiring loom to the headlight as there are white yellow and a black with white tracer wire so I cut the white wire and joined the switch in the middle and it worked how ever the wire on the switch got very hot quickly so i turned it off and also only works in off position so you know what iv done wrong or what I need to correct it thanks for any help really appreciate it
