Kawasaki buttons are little more than sealed momentary switches. A momentary switch is not like your normal on and off switches like a light.
A momentary switch on the Kawasaki Jet ski's only work or make a connection when the button is depressed. When the button is depressed to metal prongs touch a steel washer that is connected to the Ebox. When it touches it sends a signal to the ebox to either start or stop the jet ski.
