ABSTRACT:
Miniature electrical switches having a sliding cleaning action, and utilizing a U-shaped bridging element with a detent projection for engagement in between and in contact with adjacent terminals and simultaneously providing electrical connection and detent action. The bridging element may have a curved bottom; it tilts backwardly as the bottom slides forwardly over a terminal, and subsequently is tilted forwardly by the recess trailing wall. An alternative element has a rounded off leading corner, rocks over a terminal, engages the adjacent terminal, and subsequently is tilted backwardly. The limiting position is unstable and the "on" position provides a cleaner interface.
