I wanted to take a closer look at this switch that we have listed and I mean we the community of course, I looked at the router amperage rating it looks like it’s about 7 amps, in my case the rigid vacuum is about 8.3amps , the Maslow does around .6 amps max (checked during a calibration).
Anyway it looks like if you’re running the router and the vacuum from the same circuit you’re right up against the max value for a normal breaker in a house of 15 amps I’m not sure what it is exactly yet but we’ll just talk about nameplate ratings because usually that’s you know what they could max out at the unit.
The switch contacts in the e switch are rated for 10 amps but I’m not sure I’d even believe that because I am unaware of that brand and the seemingly high cost optimization within the unit, and the fact that the gland fitting is oversized and could be easily pulled out could be a safety hazard I would definitely recommend either replacing the gland fitting or putting a knot inside the unit so that the cord cannot pull out and then be live on your floor, I would certainly recommend a better more durable unit and since it doesn’t have the ground installed on it is not as much of an issue because it’s not a grounded box but if these items were to melt down in any fashion because of their ampacity not being what they should and it not being built as safe at least a metal box would short out and provide a fault that would shut that switch off but having this switch in line could be a possible liability for heat buildup and melting down before it ever reaches ampacity and causing a fire. If you were to use it just for the Maslow itself that might be okay but I don’t know if I would trust it on the router or having anything else plugged into it that could generate any heat on the contacts.
Ymmv, the switch is very cost optimized, not safety optimized.
