Popbumpers are configured as autofire_coils in MPF.

• A blade switch to notice balls
• A #444 or #249 bulb for light shows
• A coil to push the ball away.

Part numbers:

• Older one part plastic bumpers: 500-5227-00, AS-2999 (Turbo bumpers)
• Modern bumpers: 515-6459-04/A-9415 and B-9414

This is an example:

switches:
  s_popbumper_left:
    number: 7                 # depends on your platform
coils:
  c_popbumper_left:
    number: 4                 # depends on your platform
    default_pulse_ms: 23      # tune this for your machine
lights:
  l_popbumper_left:
    number: 13                # depends on your platform

This example is tested to be valid MPF config. However, it is not integration tested.

switches:
  s_popbumper_left:
    number: 7                 # depends on your platform
coils:
  c_popbumper_left:
    number: 4                 # depends on your platform
    default_pulse_ms: 23      # tune this for your machine
lights:
  l_popbumper_left:
    number: 13                # depends on your platform
    subtype: matrix           # might be differnt
autofire_coils:
  ac_popbumper_left:
