Yes, but the three position switch is spring loaded to return to the off position. So to use it what you do is wrap a rubber band around the switch, and tie it to the handle bar just aft of the switch so that it holds it in the hot position.
Works great and if you have the right size rubber band you can push the switch back to the off position and it will stay there. This is good for longer periods of time without talking, or eating. You just need a rubber band strong enough to hold it in the "I/C" position but not strong enough where is pulls it out of the off position on its own.
