hardware and electrical appliance

http://zhidao.baidu.com/question/34359663.html

交电 is an established word, and 交 has lost its original meaning. Just take the 2 characters as a whole, which has a general meaning of "electrical appliance, accessories, and tools" . In the website of most companies involved in this business, it has been translated as "electrical appliance".

Your question:
Would this be metal hardware for use in electronic?

The answer is “no". 五金 and 交电 are 2 broad categories of products which are not related to each other.

If only refers to consumer electronics, simply (Hardware and) Electronics will do.

Electrical is more power related, you could get a good grasp if you go to home depot.com under the Electrical category.

早期的一种零售店模式。最初叫做五交化商店，销售五金(hardware)、交流器件/设备(electrics)和化工产品(chemicals)，后来化工产品逐渐淡出。家电/家用电器通常不在此类商店出售。
