They say power is the ultimate aphrodisiac, especially when it's delivered in an efficient way. Just ask Eaton (ETN).

Once known mainly as a maker of truck and airplane parts, Eaton has been shifting its focus over the past decade to the "power-management" business.

The diversified manufacturer makes things like circuit breakers, switchgear and panelboards that help factories, utilities and governments save power. It also specializes in hydraulics systems for agriculture, construction and mining, among other heavy industries.

Eaton has been expanding in recent years as it anticipates a boom in global demand for energy-efficient manufacturing. It bought rival Cooper Industries for nearly $12 billion in 2012.

The focus on energy makes Eaton less vulnerable if the economy slows. But the company still has a large presence in the automotive and aerospace market, which could be at risk in a downturn. It's also exposed to volatile emerging markets such as China and Brazil.

Still, Eaton may be an attractive way for investors to capitalize on a potential manufacturing renaissance in the U.S.

The stock, which has taken a hit this year, trades at a slight discount to the broader market. Yet analysts are expecting earnings growth of more than 16% this year and 13% for the next few years.
