Littelfuse OTB (Off-Road, Truck & Bus) division merged with Cole Hersee, and we now call ourselves Littelfuse CVP (Commercial Vehicle Products).
While CVP is the best description of the heavy duty vehicle market we serve, it doesn't describe all the fields we cover - we sell lots of switches in the Marine market, for example (many people don't think of boats as vehicles). And we have switches on stationery equipment, too - like gensets (certainly not a vehicle!)
In short, our switches, connectors and modules are installed in and on anything that has a battery similar to the one found in cars.
