Where I work our pressure washer is set up with switches like that.
The first day I used it I noticed some one had left it on, so when I was done washing a piece of equipment with it I went to turn it off and saw that the motor wasn't running.
So I gabbed the pressure washer gun, brought it around to the door way where the pressure washer was located and squeezed the trigger and the electric motor kicked on while the trigger was pulled and shut off when I released it.
Hadn't see that before, I always figured something like that was possible.
I am used to the kind of electric pressure washer that stays running when you let off the trigger.
I wanted to use some of those on/off pressure switches but its not in the budget right now, at some point I will upgrade to them.
