Just moved to a home with a pool and a failed Intermatic pool timer. Installed a new one myself. 220 Volt model T104M. It's working great. The old (broken) timer had this thing soldered to the two hot sides of the switch. What is it (capacitor? surge protector? electrical noise suppressor)? Only wording on the attachment is a large A, a smaller AA and 65 in reverse letters, like looking through a mirror. What was it for? Do I need it?
