Abstract
A switching system includes: a first switching apparatus; a second switching apparatus; a holding assembly between the first switch apparatus and the second switch apparatus, the holding assembly configured to hold one or more fuse devices; and a linking interface connected to the first switching apparatus and the second switching apparatus, the linking interface having only two stable interface positions: a first interface position and a second interface position. Transitioning the linking interface from the first interface position to the second interface position simultaneously changes the state of the first switching apparatus and a state of the second switching apparatus.
Claims19
A method comprising:
- electrically connecting a fused single-throw safety switch to an electrical device configured to consume and produce electricity, the fused single-throw safety switch comprising one or more fuses;
- and
- transitioning an interface of the fused single-throw safety switch from an ON state to an OFF state to isolate the one or more fuses regardless of whether the electrical device is consuming or producing electricity.
A single-throw safety switch comprising:
- an operating interface configured to control a first switching apparatus and a second switching apparatus simultaneously;
- and
- a fuse holder between the first switching apparatus and the second switching apparatus, wherein the operating interface is configured to control whether the single-throw safety switch is in an ON state or an OFF state;
- and, when the single-throw safety switch is in the OFF state, the first switching apparatus and the second switching apparatus are OFF and the fuse holder is electrically isolated on two sides.
The single-throw safety switch of claim claim 9, further comprising the first switching apparatus and the second switching apparatus, and wherein each of the first switching apparatus and the second switching apparatus comprises three sub-switch assemblies electrically connected to one of the three fuse clips.
