Electromechanical Components Sourcebook for Engineers & DIY

I bought this book as a quick reference to many electromechanical devices. I'm finding this very useful, I've scan through the book already. I'm very happy with this purchase. In a review below, its mention that you learn this fundamental in the 1st year or second of an engineering program. This is true but as an engineer, working on various components with different elements, a simple reference works great. I bought this used for twenty something dollars which was great. I would recommend the same.
