Piper 688-307 Gray "Recognition/Landing Light" Split Rocker Switch

For those unaware, many general aviation light aircraft have been fitted with a two-pole interlocked, "split rocker" switch; this is used to control the aircraft's DC power. The split rocker switch allows the aircraft's battery to be turned on without also having the alternator on. It also prevents the alternator from being left on while the battery is off.
