The contacts on a kill switch or a kick-stand switch will burn quite easily with the power running through them but they are both cheaper and easier to replace than a ignition switch.
Because of the spring loading on the ignition switch that is my preferred way of killing my bikes.
if the kill switch is bad you should get a neutral light when the bike is in neutral and the ignition is on but the pump will not run so it is looking like your kill switch, the clutch switch will alow the pump to run but the starter will not
With my new Yamaha the kill switch is also the start button so you can't forget it.

Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
