## Description

Product Description          The Echo range is an innovative range comprised of entirely wireless, battery-less and self-powered switches, only available from MK Electric. The benefits of the items in the Echo range are numerous. Wireless technology makes for almost-instant switch installation and location flexibility, reducing disruption and cost, as well as improving speed and ease of installation--invaluable for areas needing to rearrange space periodically, such as commercial offices, or those where the channelling of walls isn’t permittable or feasible, such as historical buildings. They require no batteries, which means that the items are easy to maintain and cost-effective to run, eliminating nuisance and waste for a more sustainable option. Furthermore, the products are self-powered, using innovative technology to ‘harvest’ tiny amounts of ambient energy which power a switch (transmitter) to send an RF signal to the switch receiver which is connected to the lighting circuit, operating lighting at ranges of up to 30 m within typical buildings. The range comes backed up by MK Electric’s track record for quality and reliability. This transmitter from the Echo range of MK Electric can be assigned or unassigned to a switch receiver simply and quickly, time and time again. It is designed to complement MK’s wiring devices ranges, and each switch can operate any number of switch receivers. The make of this product is Metalclad Plus, a range of surface-mounted accessories that is ideal for factories, workshops, garages and sheds--anywhere there is heavy wear and tear. Made from heavy gauge steel, this item is tough, impact-resistant and looks good too.
