Type 86 Concealed Acousto-Optic LED Corridor Light Switch

This is a concealed-mount acousto-optic control switch designed for corridor and home lighting. It automatically turns on LED, incandescent, or energy-saving lamps when ambient light falls below 5 lux (e.g., dusk) and sound exceeds 60 decibels, then switches off after a fixed 45-second delay. It installs flush into standard Type 86 wall boxes and replaces existing single-pole switches without rewiring.
Key Features:
- Concealed Type 86 mounting for clean, integrated installation
- Dual-trigger operation: requires both low ambient light (<5 lux) and sufficient sound (>60 dB)
- Fixed 45-second automatic time-delay shut-off
- Compatible with LED ceiling lights (25W), energy-saving lamps (40W), and incandescent bulbs (60W)
- Direct replacement for standard single-pole or touch switches using live-in/live-out wiring
Ideal For:
- Indoor corridors, stairwells, and entranceways with consistent low-light conditions
- Shared residential areas where hands-free, energy-efficient lighting is preferred
- Retrofit projects requiring no additional wiring or smart hub
