Grid time lag switches (3-wire versions)

GRTLA MK
GRTLA MK ILM
DANLERS grid time lag switches are suitable for fitting into the MK
Grid Plus (MK), Crabtree grid (CB) and Eurodata plates (EU).
A short press will switch the load on and it will switch off automatically
after the time lag period has expired. The time lag can be set between
approximately 1 minute and 2 hours.
These devices need a neutral supply.
The button on the illuminated versions (ending ILM) is lit until the
button is pressed, it comes back on when the time lag has elapsed.
The load can be switched on from other locations by wiring these
devices in parallel.
