triac relay
I would like to turn on / off a couple of devices (TV, HiFi) etc with a Triac + Relay combo.
The triac will turn on at zero cross, after that a parallel relay will turn on and after a small time triac will not be triggered anymore.
Same way when turning it off.
I read that there can be problems switching inductive loads with triacs.
This on/off event is going to happen just 0-20 times a day.
Do I need any extra precaution / snubber RC etc, to switch these appliances safely?
thanks,
Zedman
