Time Lag Switches


Plated time lag switches - 2 wire versions

Direct replacements for existing wall switches.

No neutral wire is needed. Hence they are very quick and inexpensive to install.

The TLSW 10 ILM has an illuminated push button for easy location in the dark.

Product code: TLSW 10 ILM

    The circuit diagrams here illustrate a 2-way wiring configuration typical of those found on location. They also demonstrate how DANLERS Plated time lag switches (2-wire versions) and DANLERS Slave switches can be incorporated.


    These circuit diagrams use the BS 7671:2001 harmonised colour coding with the triple-and-earth colours of brown, black and grey for the lines. For clarity all earth wires are omitted. They show the physical connections with • or •• as appropriate. They use brown and blue for the line and neutral feeds to the circuit. They use twin-brown and earth for the feed to the first 2-way switch. Any unused wires are terminated with the x symbol.

    note: These circuits are only recommendations and the contractor remains responsible for their own work.
