Yesterday i had to replace a relay i installed about 2.5 years ago
This relay i used in my thermostat to use 5VDC logic to control 27VAC logic
I had used the cheap relays you can get on ebay for about $0.50 each (Songle SRD-05VDC-SL-C)
It failed cause the contact plate on the load side became dirty from electrical arcing
here is a video showing how they are designed: https://www.youtube.com/watch?v=KzR7EtPM15E
Would a 2.5 year life span be reasonable for a relay in this type of use? (defective?)
would one of these two last significantly longer (enough to justify 2 to 2.5 times the price)?
