  • Selectively concealable indicator systems and assemblies
    Patent number: 8636222
    Abstract: Selectively concealable indicator systems including an indicator assembly configured to mount behind a wall plate, which provides an interface to interior wiring and is operatively mounted to a wall with a mounting fastener. The indicator assembly includes an elongate member including a first end and a second end, a mounting pad proximate the second end, an elongate slot proximate the first end and configured to receive the mounting fastener. The elongate member is configured to move relative to and selectively behind the wall plate by sliding over the mounting fastener disposed within the elongate slot. The indicator assembly further includes a spacer disposed between the elongate member and the wall plate and is configured to receive the mounting fastener.
