Water pressure switch

[JerryLouisMartin]

I 'm trying to figure where to wire in the water pressure cutoff switch.

I attached a picture of my power supply.

I have the following

P+ G K- K+ G IN 5v

Pressure WP-------???

Normally the switch would be between G (I think) and something labeled W. What I would recommend is putting it between your controller laser enable pin and the enable pin on the power supply. I would also recommend getting a 24V PSU from amazon or something because you will get better power out of that. Also, I have had a power supply from this manufacturer before and they were using un-named capacitors which ended up exploding. I suggest you give a electronics hobbyist a case of beer or something to get them replaced.
