Can you still buy Arc LS Twisty switches? I have the clickie switch now but want the twisty.The reason is I carry mine in the belt pouch that came with it from ARC. While out on the lawn tractor doing some work it came on without me knowing.A day or two later I went to use it and it was completly dead.Unless there are a lot of problems with the twisty I may want to change or at least try out a twisty.Thanks for any info.
