Abstract
A waterproof push button switch does not need to be covered with a resin to a height at which a divided connected portion of a case for the switch is hidden by the resin in a height direction and the divided connected portion may be waterproofed. A gap () is formed between a peripheral wall portionof a base caseand a second cylindrical wall portionof a cover case, and between an opposite surfaceof the cover caseand a waterproofing seal member. The gap () extends from an opening portion of the base case fitting chamberto an annular watertight seal portionto completely surround a periphery of the watertight seal portion. The thickness of the gap portionis determined so that the resin entered into the gap portionfrom an opening portionof the base case fitting chamberreaches the watertight seal portionby surface tension.
