CR2032 powered remote wall switch (schematic and tests)

The use of a standard CR2032 lithium cell in one of these switches is a refreshing change from the common miniature 12V batteries. It should theoretically have a very long operational life. The switch came with the battery separate, but opening it the first time was extremely difficult. I thought it was going to break. I could see some of these being damaged just trying to put the battery in for the first time. Other listings show a battery pull tab. I've ordered a version with external battery drawer for us to take apart.
