These dual-function pots can be used as a normal volume or tone control, and they also pull up to activate an on/on double-pole double-throw mini switch. They can control pickup phasing, series/parallel switching, coil-taps, and more.

250K vs. 500K
Generally, 500K-ohm pots are used with humbuckers and 250Ks are used with single-coil pickups. 25K pots are used for active systems.
You can use any value you like, but a 250K will give a slightly warmer tone than a 500K pot. The 250K pot bleeds off (attenuates) some of the high frequencies to ground. A 1 Meg-ohm pot will attenuate even less than a 500K pot, so if you want to hear your guitar "wide open" you may want to try one.
