ABSTRACT:
A switch is disclosed having a switch element comprised of a laminated structure including a fixed contact member and a movable contact member spaced apart with a spacer interposed therebetween. The fixed contact member and the movable contact member have respective terminals extending out of a case body of the switch and are adapted to be soldered to a soldering land of a printed circuit board. The switch is improved by providing a projection between the switch element and the case body for creating a space. The space created by the projection prevents solder flux from moving by capillary action into the contact portions of the switch element.
