Dear All,
I have a circuit with a 12V, SPDT relay (250V 10A) and the load is ac
resistive, 220V, 8A.
When I apply 12V to the coils from a dc power supply, I can hear that
the relay gives a "click" sound, but when I measure the proper output
legs, I found that the relay actually didn't throw (i.e. opens the NC
contact and makes the NO contact closed).
I tried several times and suddenly the relay "click" sound became much
louder and then it worked properly.
Any clues? Poor contact or anything else?
Thank you very much!
Billy
