[Q] N.C. relay release contact bounce

[Nicholas]

My N.C. relay always bounce for about 5mS when release. Any idea to help debouncing? Sunbber circuit? I try put a 0.015uF/630V cap in parallel. But didn't help. Thanks for any help in advance.

Nicholas.

yaa,for debouncing we always snubber circuit.

The debounce technique depends on what you are doing with the contacts, and why the debounce hurts you. Can you tell us?

I m using this relay to switch the AC power which can be up to 20A. I already do the zero crossing. And need a way to get away the relay contact bounce when release. BTW, how to calculate the snubber circuit component values?? Thanks.
