I've had a couple little electric pressure washers. What I've found works is
to hook up the garden hose, and then squeeze the grip handle on the nozzle.
Leave the electric off. Eventually, the water will dribble out the nozzle
just from garden hose pressure. (ten or twenty seconds).
You may also have a clogged inlet screen, or something blocking the low
pressure water line.
As to the micro switch. The ones I've had, when you close the nozzle (let go
of the handle) the pump runs for a second or two, and then the micro switch
turns off the pump. When you sqeeze the handle, the pump turns back on.
