Jeff,
I do not know if you are the right person if not, please disregard this.
I have a few problems with the debian rules file from the latest git
pull, trying to compile under debian lenny with kernel 2.6.30.5 and
rtai 3.8
here is the relevant line in the rules file:

I'm looking to source an e-stop switch. I have some already with the
big red mushroom button that latches when you press it, and must be
turned to release. This is good. But what I want is a switch that can
also be operated by a signal from the computer. So if the computer
detects an e-stop
Hi Neil,
Setup a failsafe circuit with the connection passing through the E-stop
contacts energizing a relay. If anything in the series circuit becomes open
(E-stop button, relay contacts in E-stop circuit, overtravel limit switch
contacts, etc.) the functions dependant upon that circuit
Thanks Jim,
I understand how to set up such a failsafe circuit. But in addition, I
want the actual e-stop switch to activate and latch, so that
regardless of whether the computer generates a fault condition, or I
do it myself, I still have to manually release the switch before
resuming operation.
My guess is that a switch with an actuator in it would be so expensive
that nobody has ever bothered to market one. I think your best bet is
to have a self-powering relay that can only be turned on by a
momentary switch.

Hi Neil,
I believe Eric is correct. After 30 years in industry (the last 20
specifically with CNC) I have never seen what you are describing. As Eric
mentioned, a relay that must be activated by a reset switch would do the
job. Reset switches for this purpose I have seen and included in
OK, thanks. I guess they don't exist.
I guess what I'll do is to add a circuit that requires the e-stop
button to be pressed before a fault condition can be cleared. Then I
have no choice but to twist the e-stop before resuming.
Thanks,
Neil

Hi Neil,
That is easy doable by adding contacts on the E stop switch and creating the
logic to achieve the effect you desire.

Just use a safety relay for this, no need to reinvent the wheel..

What's a safety relay? Is it a particular kind of relay?

Basicly they are a relay, with some aditional circuitry inside so that
bad things can't happen.
if you have a glitch in the safety circuit, the safety relay opens and
stays that way until you
