General Wire Air Foot Switch Parts: Diaphragms, Hoses and Pedals

Most General drum machines start from an air foot switch: you step on a pedal, air travels down a hose, and a diaphragm in the switch box closes the switch. When the machine stops responding to the pedal, it is usually one of three small parts.

Troubleshooting in order

  1. Unplug the machine before you open anything.
  2. Check the hose for cracks, kinks or a loose end at the pedal or switch box. A leak means no signal.
  3. Squeeze the pedal and feel for air at the switch end. No air: the pedal bellows is the problem.
  4. If air arrives but the switch does not click, the diaphragm inside the switch is the usual suspect.
  5. Still nothing? The switch itself or the motor may be the fault. Call the counter with your model and serial.

Counter tip: If you are not comfortable working on electrical parts, have a qualified repair shop do it. Always test the GFCI on the cord before use.
