A polarity-reversing switch comprising first and second contacts, which need not be parallel to one another, lying in a common plane ane provided with respective openings which are aligned with the openings of contacts disposed above and below this common plane so that switch elements can be received in the aligned openings. The switch elements are mechanically coupled for mutually reciprocal motion perpendicular to the planes of the contacts. Each of the switch elements carries a plug which is geometrically similar to the openings and snugly received therein. |
