I'm building a small stripboard audio switchbox using some hamlin 5v reed relays (HE3621A0550, mouser link here).
A small SPST momentary switch activates the relay. Wondering if the best practice is to ground the relay from the switch (sink) or send current to the relay (source) from the switch. Since the switch is SPST, the other end (ground or current) would be permanently wired to the relay from the switchboard.
I am leaning towards sinking but I wanted to make sure this was a safe practice.
Any other general tips to ensure a long lifespan and good, safe operation for these relays?
edit: I am aware that the Hamlin relay I selected is not latching. The momentary switching is intentional.
