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.
