Question about relays

Submitted by kangyunmei on Thu, 11/29/2018 - 19:00

I have a project I am working on that I am using a relay, but I'm not sure if its the best way.

I have a 5vdc point that goes to 0vdc at some point in time. When its at 0v, I have to ground a trigger wire. I found a small relay in my spare parts that is working but I'm not sure if I'm using the relay properly because its kept energized most of the time. Is keeping a relay energized a bad idea, can it burn out or cause problems? 

The relay in question is hjr1-2c l-05v
