I need a double-pole single-throw relay in my application. I simply need two sets of N.O. contacts that close when the coil is energized. Nothing else. When the coil is not energized, I want no circuit energized.
When I go to purchase a DPST relay, I find them relatively unavailable, as opposed to DPTD relays, which are far more common.
I don't see any harm in using a DPDT, it's just that the power voltage will be present at the unused contacts.
No big deal, I'm just curious why DPST seem to be relatively scarce. And I also thought I'd make sure I'm not missing something. Like... NOOOOOO for god's sake don't use a DPDT when you really need a DPST!
