How Do Kill Switches Work

A kill-switch is a very simple device that relies on a spring-loaded button to keep the switch open (ie off) when you want the engine to run. There is a clip which fits under the button of the kill-switch and the clip is attached to a tether which is also attached at the other end to the person controlling the boat.

What is the purpose of engine kill switch?

A killswitch is a simple emergency-off switch that turns off the machine in a click. It acts as a simple safety mechanism enabling the driver to turn off the bike when it cannot be done manually. It shuts down all the running systems without causing any damage to the system.

Is a kill switch normally open or closed?

Most tether kill switches sold are normally open with the tether key installed. Once the tether key is removed, the switch will close itself, creating a short to whatever circuit it wired to.
