New to this site. I saw a topic on Intermatic In-Wall time switches used in a 4-Way application, so I thought I should help.
I'm a very experienced Engineering Tech with some small design experience. I studied electronics in the US Army and worked on Advanced Avionic equipment. After the Army I studied engineering in college, but hadn't finished. Back in college again after 15 years. I worked in engineering for various test and measurement companies then got into the world of Lighting. I worked at ESI, ULT and Philips-Advance. In lighting I worked on electronic ballast, LED drivers, Addressable systems, Compliance, etc... For a while I also worked in Technical Support for a timer company, then went back as an Engineering Tech Manager for a battery charging company.
