I note the following in the item description
The mushroom push switchs are used in industrial controlling circuits for controlling in electromagnetic starter, Contactor, Relay and other electric circuits.
So its doing what it siad it should.
Do be aware that the latching ones dont meet the safety needs so probably only ideal for home use 
I've just tested it, when stop is energised, the system does remove power and needs to be re- energised before restarting. However this about the latching knob not being OK, as the machine might unexpectedly restart when its released, well the reason you are releasing the stop button is to restart the machine, so you are expecting it to start, so....

Its the doukle failure job. The latching ones are easy to release and hence why they dont tick the boxes (because reaching over cab twist release them)......it gets worse when you start having to consider DC brake setups to!
