So... What is a MOSFET switch?

A MOSFET switch is a solid state electronic switch that takes the power normally sent through the trigger switch assembly and instead routes that power through a Mosfet (Metal Oxide Semiconductor Field Effect Transistor).

In this way the trigger switch is only used to send a very low-power signal to the MOSFET switch. The MOSFET switch then turns the current on and off without any arcing or damage to the trigger switch and wear is virtually eliminated and its lifetime is extended indefinitely.
