Product Description
Ordering Key
Mono-function, plug-in, delay
on release, miniature time re-
lays up to 60 s covering 2
individual time ranges. These
economical timers are often
used to switch on an exhaust
fan and keep it running for a
certain period of time after
disconnection of power sup-
ply.
