Good communications are essential to a successful flight. This convenient switch mounts to the yoke with a hook and loop strap, allowing pilots to use their thumb to puch the button and communicate with ATC, Unicom, or other aircraft. Eliminates the distraction of picking up the microphone and provides hands free communications that keeps pilots focused on flying the aircraft. Particularly useful for rental aircraft, which typically might not have push-to-talk switches installed. Lifetime Warranty.
