Safety & Comfort Units

Two- and three-wheeler EV drivers physically control their vehicles with safety and comfort units. A block diagram shows how Littelfuse components help those units function. We supply C&K tactile switches for handlebar controls, thermistors for lights, resettable PPTCs devices for USB ports, and reed switches for side stands. We also offer many overcurrent and overvoltage protection solutions.
