• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

I'd like a big emergency stop button in the form of a simple 240V extension lead. For plugging in a router, planer, track saw, or mitre saw. I don't want to do any wiring. I don't care too much about NVR, but it's not a problem if it has NVR functionality. I'm mainly just looking for a big reliable button. Does anyone have any recommendations?
 
Axminster sell a nice NVR switch. A similar one came with my router table frame, although mine had the stop button disc over the top of the actual buttons (so I removed it).

This one isn't the same as mine, but looks pretty good.

PS: when you wire such a box, the stop disc goes upstream of the stop/start buttons (on the incoming mains side). That way it causes the NVR to operate, so the motor circuit stays off when you release the disc (restart with the green button). That's simple but important.

The blades on the back of the components used to be known as "Lucar" connectors (after Joseph Lucas, "Prince of Darkness"). It's well worth using proper crimp connectors to make off the connections neatly. You can solder to those blades, but that needs a chunky soldering iron and risks melting insulating pieces inside the switch. The correct cable ends and cheap crimp tools are available from places like Halfords* and Ebay. They are colour-coded by the size of wire they take - I think you'd need the blue, middle-size ones (red is smallest and yellow is too big).

*OK, nothing cheap is available from Halfords, I know!

PPS: I think Axminster also sell versions with a built-in 13A outlet socket (mine is like that). You probably still have to wire the inlet cord, but not mess with the individual switch parts. Do a search on their site...
