I'm looking for a relay with a 3V coil for a residential wall thermostat ap plication. So, the contacts would activate A/C or the furnace. Many of th e very low coil power relays are listed as "signal relays", and they appear to be a good fit in general. The one I'm looking at in particular is TE I M21GR.
The contacts are rated for resistive loads, which I *think* would be ok, bu t I'm not entirely sure. The contactor in an A/C unit, while inductive, wo uld seem to behave mostly as a resistor when power is first applied (versus trying to start a motor).
I'm trying to avoid relays that draw a high amount of current because it'll generate more heat.
Are these "signal" relays ok to use for most applications except motors?
