Greenbrook Electronic 7 Day Wall Switch Timer - T40S
Upgrade your lighting or security circuit with the Greenbrook T40S 7-day electronic wall switch timer, built to replace a standard wall light switch while adding programmable automation. This timer integrates directly in line with your lighting circuit, allowing up to 6 on/off programs per day across a full weekly schedule (or 24-hour mode). Designed for ease, its display, programming buttons and hinged cover make setup and daily override intuitive.
The T40S supports a 230 V supply, with a switching capacity suitable for loads up to 400 W (GLS) and compatible with many low-energy lamps. It features a 100-hour battery backup, so your programming remains intact even during power cuts. Its slim, unobtrusive profile — measuring 86 × 86 × 27 mm (HxWxD) — fits neatly in standard wall boxes without bulk.
This timer retains manual operation: you can override the schedule and use it as a normal switch while programming remains intact. Built to industry standards (EN 60730-1 / 2-7), the Greenbrook T40S offers both advanced automation and dependable safety in one single-gang unit.
