Wirthco Engineering

Smith Auto Electric is proud to be a warehouse distributor of Wirthco Engineering products.


Wirthco Engineering is the home of the “Battery Doctor” and as such has dedicated their resources to finding and solving many of the hard to solve solutions that we have in the DC industry. We are proud to stock their award winning products that are of high quality and well thought out answers to the industry wide issues.

They hold the US patent on many of their products and items like their “knife” switches are often imitated, but never duplicated. Their dedication and quality are the reason we here at Smith Auto Electric are proud to be the WD for their products.
