E55527001 Magnetic Reed Switch
Used on the BP555e machines. When the lid is lifted the machine will not operate.
This new style switch, when installed on the machine, resembles a black rectangle that is flush with the top of the left side frame.
Older models had a switch that looked like a grey circle ~1 inch below the top of the left side frame. For older models, you will need this switch.
