Abstract
An air break electrical switch includes a first electrical terminal and a second electrical terminal supported apart from the first electrical terminal. The switch further includes a blade support configured to be electrically insulatively supported apart from the second electrical terminal. A blade is pivotally supported by the blade support, and the blade is pivotable from an open contact position to a closed contact position and vice versa. The switch further includes an indicator connected to the blade. At least a portion of the indicator is fixed to the blade so as to rotate with the blade and display a first color when the blade is in the open contact position and obscure the first color when the blade is in the closed contact position.
Claims20
An air break electrical switch, comprising:
- a first electrical terminal configured to be electrically insulatively supported by a utility structure;
- a second electrical terminal configured to be electrically insulatively supported by the utility structure apart from the first electrical terminal;
- a blade support configured to be electrically insulatively supported by the utility structure apart from the second electrical terminal;
- a blade pivotally supported by the blade support, the blade being pivotable from an open contact position to a closed contact position and vice versa, in the open contact position contacts of the blade being spaced apart from the second electrical terminal and in the closed contact position the contacts engaging the second electrical terminal to electrically connect the first electrical terminal and the second electrical terminal;
- and
- an indicator connected to the blade, at least a portion of the indicator being fixed to the blade so as to rotate with the blade and display a first color when the blade is in the open contact position and obscure the first color when the blade is in the closed contact position.
An air break electrical switch, comprising:
- a first electrical terminal configured to be electrically insulatively supported by a utility structure;
- a second electrical terminal configured to be electrically insulatively supported by the utility structure apart from the first electrical terminal;
- a blade support configured to be electrically insulatively supported by the utility structure apart from the second electrical terminal;
- a blade pivotally supported by the blade support, the blade being pivotable from an open contact position to a closed contact position and vice versa, in the open contact position contacts of the blade being spaced apart from the second electrical terminal and in the closed contact position the contacts engaging the second electrical terminal to electrically connect the first electrical terminal and the second electrical terminal;
- an indicator fixed to the blade, the indicator having a first portion and a second portion;
- an obscuring member fixed to the blade support and overlying the indicator, the obscuring member having a plurality of apertures such that the indicator is visible therethrough;
- and
- wherein in the open contact position, the first portion of the indicator is visible through the apertures in the obscuring member to indicate that the blade is in the open contact position.
