Torch Relay tech specs

What are the technical specs on the relay that turns the torch on and off?

I’m wanting to turn on and off a laser diode and need to know if it can handle 12v and 4 amps.

I have a picture posted of the (reed) relay. Don’t recall the exact specs but from what I remember it can only handle a small amount. Maybe less then 1 amp @ 12v.

I’d like to set up an E-stop on my table as well, can you post a schematic or wiring diagram of that?
