low voltage relay?

jimbo198966 · Mar 9, 2009

hi, i'm new to electrics....
is there such thing as a low voltage relay? i need a relay that 'switches'' at 2.5volts (or lower)
ive got this one: http://us.100y.com.tw/pdf_file/LU-SERIES.pdf (lu-12), but 2.5v isn't 'strong' enough...
if that makes sense? thanks

hi what are you trying to switch? have a look at RS components or maplin you can get a slave relay
to switch the coil on a larger relay give us some more info on what you are trying achieve

hi jimbo

from that data it seems like you have a 12 volt relay, so yes 2.4v wont be strong enough to switch it.
have you tryed RS or Maplins, relays are available in many coil voltages to suit nearly all applications then you pick your prefered contact capacity, job done.
what is it you are wanting to switch with(trigger voltage) and what are you wanting to switch ( voltage / current)

Hope this is of some help.
