For some reason I could not reply to this post?
All the interlocks are in series and connected across your LPS enable which depends on what LPS you have? i.e P+/gnd, WP…
On the site you can find links to the original schematics if you want better quality images.
A complete protection wiring schema for a LPS with P+ is: P+, front cover, back cover, water flow switch, temp alarm, anything else that you want to shut off the laser if not working , gnd. The contacts of these devices are in series.
The current is small about 5-10 ma.
Relevant sections of the blog where there are links to the parts and detailed schematics:

Help. I don’t like to ask newbie questions but that is what I am.
I joined the group about 1 month ago and received my k40 Monday. I want to make sure I do everything right and not make any stupid mistakes. Right now, I am looking at setting up the cooling and safety lockouts. I looked through the post topics but they are not sorted very well. I have been looking through http://donsthings.blogspot.com/ and there is a lot of useful stuff there but his interlock diagram didn’t make since to me and was low resolution and hard to read. I read through the post on what type of water to use and plan on using distilled water and algaecide. I am having trouble finding the right flow meter/switch to use for my safety circuit.
Are all the switches just put into series, if so, how much current flows through the circuit? I also was not able to find where it hooks to the control board.
Feel free to add any advice you think I might need. I have read alot about laser alignment and downloaded some of the recommended guide and I don’t think I will have problems with that.
