International Classification:

H01H 19/00

H01H 19/58

US Classification:

200 11R, 200336, 200564

Abstract:

Implementations provide a first option of simultaneously turning on or turning off two distinctly separate and isolated electrical circuits, such as when each of two electrical devices are powered by a different energy source. Implementations provide a second option of connecting the two separate circuits together, such as when both of the first electrical device and the second electrical device are to be powered by both of the different energy sources connected in parallel. Included is an electrically isolative rotor internal to a housing. The rotor is keyed with an external knob used to control rotational position of the rotor. Further included are electrically conductive link bars contained by the rotatable rotor that electrically couple with stationary bus bars dependent upon rotational positioning of the rotor. Other implementations of the enhanced switch are envisioned including another depicted implementation discussed allowing for a double-pole, double-throw switch.

Abstract:

A modular family of electrical switching relays that utilize interchangeable mechanical override knobs or blank fillers, combined with enclosures capable of containing two or more independently operable relays; where each independent operating relay can selectively be constructed to either have a mechanical override knob or to have a blank filler thus resulting in a broad number of product permutations from a minimum number of unique components that are required to build those permutations. An electromechanical relay with rotary manual on and off override control where the manual on and off control consists of three distinct positions for (1) forcing/maintaining the relay on, (2) forcing/maintaining the relay off, and (3) allowing the relay to automatically turn on and off or to be remotely turned on and off with an electrical signal. An electromechanical push/pull relay with manual on and off override control where the axis of rotation of the manual override control is perpendicular to the axis of relay push/pull direction.
