Hi!
I am looking for a
e-stop with remote
feedback.
Scenario, we have several shots of confetti from in front of the
stage. I want the crew to gave an
e-stop that they only
release when it is safe to fire. So far very easy and no problems. However it works be nice with
feedback that everything is ready that is not dependable on radio communication. My first idea was a 4 pole
e stop with the one pair for control of the gear and the other pair for lightning a small light by the controller indicating everything is ready. I have not found any 4 pole
mushroom buttons though. Anyone know of a nice solution for indicating status of an
e stop that is not under load?
@SanTai I'm going back more than twenty years to a time when I was head electrician building the first AC servo automation systems on Broadway at a time when everyone else was still doing DC servo drives. Everybody else was using Allen-Bradley push buttons but we were using a European
line and loving them. The
line we were using were totally modular. I want to say the company was Sprecher and Shuh (Spelling?) They offered
mushroom headed E-stops in two diameters, illuminated and non, and they could be any number of poles from one to as many as you wanted to
bolt on to the actuator. Doing four poles of normally open or normally closed or any combination was no trouble whatsoever in latching or
momentary. They even had a
line of pneumatic time delay modules that kept the TUV inspectors happy in Germany. Not only were they fully modular and with every option covered but their pricing was better than Allen Bradley and they had great
stock, support and delivery in Canada.
EDIT 1: Here's a link to Sprecher Shuh's push buttons and pilot lights which may be of help. I suspect Sprecher Shuh is available to you in Sweden.

EDIT 2: Corrected spelling of Allen Bradley.
EDIT 3: All of their buttons, rotary switches, and indicators mounted in ROUND holes, even their square buttons and indicators mounted in round holes. This is a serious plus when you're a small shop in the world of
'perpetual prototypes'.
EDIT 4: They had an accessory which allowed padlocks to be fitted to lock-out their buttons, they had a
line with keyed activation, including removable
in one, both, or any of three positions but the pad-lockable accessory allowed you to use locks you already owned and for which staff already had keys.
EDIT 5: @SanTai Maximum number of poles is limited only by the available depth of space behind your mounting panel. Contact modules
bolt on to the rear of any / all of the various actuator modules. Contact modules may be one or two next to each other by as many modules deep as you have space to accommodate. Additional modules may be added at any time.
EDIT 6: Added an omitted word.
Did I mention I
REALLY grew to like their
line of buttons, rotary switches, indicators and contactors? [And their sales staff were always pleasant and helpful to deal with. A lady named Sherrie was my best contact.]
Toodleoo!
