Be careful, the HY56 doesn't explicitly say it is an electromagnetic switch.
I know they have the paddle built in but they expensive given the quality of the switching mechanism is unknown.
In 2011/12I I purchase several dozen similar switches to those from AE, some for me and others for the mens shed.
A couple are noisy (they hum) suggesting the EM side may not be working correctly.
We have a few switches left but I no longer use those switches on any machinery drawing more than a few amps.
For that sort of money I'd be looking at these switches from Radio Spares in Osborne Park - They don't have everything in stock but can get it in generally overnight.
Buy No Volt switch online from RS Components
If a switch doesn't work replacement is a trip out to osborne park instead of endless emails etc
All of the RS switches work to their full rating and are all still working fine.
The paddle is very useful not a deal breaker as a bigger and better paddle can easily be home made and added on.
My BIL has made a paddle for his drill press switch that is about 150mm wide and he can operate wit with his forehead.
