I'm doing a photography project, where I want to wirelessly set off a series of old flashes (Vivitar 283) with staggered time delay.
These flashed are cheap robust and plentifull (I have about 10), but has a high voltage over the flash shoe of about 280V in the "worst" examples.
The time delay relay switches that are most common, cheap (by far) and simple, is the ones equipped with a 555 and the Songle relay mentioned in the heading.
The Songle has a max spec of 250V AC 10amp and 30V DC 10 amp.
The switching time for the wireless flash triggers is about 5 to 20 milliseconds (from what I can gather), with no continuous current.
My question is: will I be fine with such a short switching time even if it goes over spec?
Isn't the spec meant for continuous current (of AC or DC)?
Would 280V and whatever small amperage into the relay do immediate or long term damage?
Also remember in this particular application the relay is not going to see more than at the very most 10.000 actuations over it's lifetime.
It's a quick (when the relays arrive) and cheap experiment to do.
But is it worth bothering?
Or is there a better option?
