Abstract Mainly introduces comparative test of creepage distance and clearance based
on rocker switch, particularly elaborates on measurement methods and pathway for
basis preferences and creepage distance and clearance between two electriferous
parts, and analyses the possibilities resulting in the typical inaccuracy.
Keywords creepage distance; clearance; comparative test; pollution degrees
