Huh???

Huh???

How are you wasting energy by not switching eggress? A battery charged is a battery. Ahhh, you mean normally lit signs, not just lights. They new ones are LED type. Wasting energy, or pinching pennies?
Nope, I wouldn't use that method. The added safety of having them constantly lit outweighs the cost of lighting LED's in my book.

No they are emergency spot lights. They only come on when the power goes off. Are you trying to sell these new fangled thingy's?

The description of the purpose of the switch said nothing about egress lighting or exit lights. Those remain on continuously as long as the building is occupied. It discusses only ROOM lights, e.g., exam rooms, conference rooms, any room that has the lights on only when it is occupied (in use). About 20% of the light switches in a typical health care facility would fall into this category (a significant market).

Use this invention so that I don't have to obey the codes? Nah. I'll pass.

You didn't read far enough. It does meet the NEC requirements by physically separating the two sets of poles while allowing the two sets of poles to be operated by a single toggle handle.

You didn't read carefully enough. The switch is to be used to control lights in a room (e.g. fluorescent troffers) that requires both normal and emergency lights. Typically when you walk into an exam room or conference room in a health care facility you have to switch two separate toggle switches. This invention allows the use of one toggle so that you are assured that the emergency lights are always switched on along with the normal lights. There was NO mention of batteries, egress, or exit lights.

I've commented on this forum before that I thought something like this would be useful. However, I pictured something more like a single DPDT switch with a barrier attached to the middle of the switch.

I think it would be useful in some cases, but I don't see a UL listing on it yet.

The new energy code complicates things also. Many areas I would have used this switch in now require some type of double switching simply because there are two lights in one room. And now lighting control panels are a requirement in almost all our projects.
