Hey guys I am new on electro tech,
I'm building a test unit for a personal project but it could be potentially dangerous if left unattended which is why I am trying to figure out a way to make it more safe in the event of a power failure,
I was wondering if there was such a thing as a pushbutton switch that turned itself off if power was cut to the circuit (that sounds confusing)
Essentially what i am getting at is, if you have a saw (this is not actually for a saw, but a unit i built from scratch) and it is on and then there is a power outage, the saw's switch is still on, but the saw is not powered or working. When the power comes back on the saw will start up and may cause injury. To fix this problem the aforementioned switch would ensure that when power was returned to the saw it would not turn on.
This is not the exact application but something similar.
Are there products out there for this idea, or would I have to build something myself like with relays and electromagnetics and stuff.
I talked to a store owner and he had a really bad accent
and he said something about latching relays and a momentary push button, and it sounded pretty cool but I had no idea what it was about
(some things i remember from the conversation was that there are a couple or a few relays and 1 controls the other)
that solution seemed like I would just need to wire it up but at the moment i really don't know how i would do it,
do you know what he was talking about?
Lemme know what you think,
Thanks,
Jake
