Abstract: A printed circuit board mountable switch includes a insulative body having a plurality of leads extending out of the body, the leads being formed into two parallel and opposed rows with fixed ends of the leads being spaced apart and facing each other on the floor of the body. A slide switch element includes a bow shaped element having first and second contact elements adjacent to respective first and second fixed ends of the leads. The switch element is moveable between a first position where the switch element bridges between the associated first and second lead fixed ends, to a position where the second contact portion only, is in contact with the second fixed end of the lead. A cover is inserted over the housing which encloses the assembly. The cover includes a lip which extends downwardly into a peripheral channel of the housing. The cover and housing are ultrasonically welded together and the tip of the cover melts and flows within the channel but is prevented from flowing into the switch housing.
