ABSTRACT:
An electrical switching device is disclosed comprising a first and a second support member engageable with one another forming a housing. A plurality of first and second contacts are mounted to the support housing and urged to be in contact with one another. A switching member such as an insulator having a plurality of contact apertures and a plurality of indexing apertures is movably mounted to the support housing and interposed between the first and second contacts. The insulator switching member separates some of the first and second contacts and allows electrical engagement of the others of the contacts through the contact apertures. The invention includes indexing means comprising a solenoid and an indexing member having an indexing arm to engage with an indexing aperture to move the switching member and the contact apertures to cause engagement or disengagement between the plurality of first and second contacts.
