This is our BRAND NEW, GOLD-plated dome switch for use on the original CX40 Atari 2600 & CX24 Atari 7800 controller PCB's. The original dome switches have often failed over the past 30+ years and these new dome switches will bring your original Atari 2600 & 7800 joysticks back to their BEST working condition! They are GOLD-plated on the bottom contact side for the BEST possible lifetime operation.
Pro-tip - These domes also work on the Atari 5200 trakball and the original Mattel handheld games (football, basketball, etc.)
