Locking switch for workshop

JDW

I have two small machines running from a dedicated 16a radial circuit both on switched fused spurs 

I want to add some safety so the machines cannot be operated, I was thinking of adding a locking switch in the circuit  

Would this switch (see link) fitted before both the machines be adequate?

    Depends a bit on the load and what exactly is being isolated -  I tend to go in at the roots and cut off all sockets, and then a larger 32A switch or so but if this is just a single load then the key switch is neater and more likely to be actually used - faffing with a padlock that is in the pocket of the other jacket or something makes it likely to be left off.

    Personally I have a stop go push button type thing with an extra e-stop on the doorframe, but that supplies a 1920s open belt driven lathe and a number of mechanical and electrical things that are all finger nipping good on the bench, so unless your risk is similar then you probably do not need to copy my paranoia.

    And if you are like me, then the kids grow up  in a few years and soon are better on the machines than I am…
