The Lancer Switch Cherry DB1 is the precision micro-contact component responsible for triggering the dispensing cycle. When the mechanical lever is pulled, it depresses the plunger on this switch, sending a low-voltage DC signal to the main control board to actuate the dispensing solenoid.

Symptoms of Failure: If the station has power but no product flows when the lever is pressed, this switch is likely failed. You may also experience 'intermittent dispensing' where the customer has to press the lever multiple times or use extreme force to get a response.
