ABSTRACT:
An automatic switch comprised of a dual-contact switch mechanism, a bimetallic thermostatic element, a solenoid-style tripping device, and an arc chamber complete with deionization plates. To eliminate one of the three electrical-hook-up steps (one, the physical attachment to a mounting, and the two electrical terminal connections), a group of components is provided for the switch assembly, including a plug-like terminal, which forms one end of the switch's electrical terminals on the rear housing wall, and an additional snap-action holding element disposed at the distal part of the rear housing wall from said plug-like terminal. The automatic switch incorporating these components can thus be snap-mounted onto a conductor rail by means of said plug terminal and onto a separate nonconductive mounting bar or rail--all in a single step. The remaining conductor can be wired-up in the traditional way thereby placing this switch in a circuit by only a two-step procedure.
