Good to know

The Merten 627819 is supplied as an insert only; the rocker or toggle cover and frame must be ordered separately according to the desired design. It is rated IP20 for indoor use when properly installed with a compatible cover. The operating temperature range of -5 °C to +40 °C makes it suitable for most indoor environments. Always ensure installation is performed by a qualified electrician in accordance with local regulations.
