Abstract
The identification of the last-actuated of a plurality of parallel connected switches is provided by energizing a light source associated with the last-actuated switch and by providing a coded output signal which identifies the switch. The identification of a closed switch is accomplished through the use of logic circuitry which periodically imposes a potential difference across all of the switch associated light sources. The potential difference is sensed via the closed switch and functions as an initiation signal which causes generation of a coded output signal and maintains energization of the light source.
