Cut the switch off & strip the wires back about 1/2", then tin & solder them together & insulate the joint- or just replace the switch with a $2 heavier duty item from radioshack etc. Not a difficult procedure and it wont void the warranty either- no special tools or solder required, they are only normal copper wires underneath the insulation, a 20watt iron should work fine + normal lead-free solder.
