I just need a big red NC switch, of the right rating, in series with the live feed,
With an NVR switch all you need to do is put the E-Stop in series with the normal STOP button and it will perform the same function using the E-Stops N/C contacts. Remember that a true E-Stop will stay operated until released, some just a twist others can have a lock.

Indeed. I was thinking the live feed is more accessible, without having to open up the NVR and make a hole for an extra cable.

Most of these consumer/hobby NVR switches are mechanically operated and these cannot have extra stop switches wired in. One exception I know of is the 5 pin KEDU where the 5 pin is connected to a temperature sensor in the motor and these can have Estops fitted but the ones for plug in loads like routers wont have this 5th pin arrangement.
Generally these cheaper NVR switches are the work of the devil and whilst they meet the safety requirements of NVR, they offer no motor protection and no versatility for extra stop switching.
DOL starters correctly matched to the load current are far far better and versatile

We can all do whatever we wish in our own workshop but I for one feel that the risks in a home workshop can be at least as much or even higher than in an industrial setting sometimes, my reasoning is simple, one person working alone, distraction, loss of concentration, using machinery only occasionally so less familiarity, maybe with less than sharp blades, trailing cables etc. we all take risks sometimes and accidents happen plus there's often no one around to help. Why make a bodge up when it's not too expensive to do it properly?
I think it's better to err on the safe side and that means NVR switches where possible as far as I'm concerned, even the cheap cr*p Chiwanese ones are better than none - just my opinion.

Apologies as this topic is above my head, but I saw this a while ago, which seems to be what "Spectric" was referring to and thought it might be of interest:

They have dropped these from their range and now sell an IMO one which is dearer.

Well initially I have gone for a standard NVR with trailing lead, the thought being I can put something more permanent in the future and use the switch again on something else. I like the idea of a DOL but wouldn't know where to sart.
