Hi all,

I have a question about the contact current specs of relays.

I need to switch a PWM signal for a solenoid between two PWM sources. Let's
assume that I switch the relay when both PWM solid state drivers are off.

Would I have to use the peak current of the PWM signal to match the contact
current, or is the resulting average current ok? (The second case would
result in a much handier relay...) I'm talking here about average currents
up to 3 A, with peak currents maybe up to 15 A or so.


If I can't guarantee that both PWM drivers are off when I switch the relay,
I guess I have no choice anyway and need contacts that are able to handle
the full peak current. Right?

Thanks,
Gerhard
