EL 21 Switch V4 P60-80
Applicable for:
- AVA Master: P60, P70, P80, both Master 1.0 & Master 2.0
- Evolution: P60, P70, P80
This is the main electrical switch responsible for turning the machine on and off. It is mounted inside the switch box and activated by the external rotary knob.
The switch is a standardized component used in various pressure washer models.
The micro switch which is directly connected is also included. We recommend to always change both if one has a failure.
*Recommended for highly skilled technicians only
Note: This part is widely available from multiple manufacturers. If you consider a third-party replacement, always compare voltage, current, mounting format, and pin configuration with the technical data shown in the product image. Even minor differences can cause malfunction or pose safety risks.
*Although this switch can be replaced on its own, we strongly recommend replacing the entire switch box assembly. The root cause of failure is often not the switch itself, but damage or wear in the plastic mounting tracks where the switch is installed. If these tracks are cracked, bent, or misaligned, a new switch may not sit correctly – and the problem will return.
Looking for the complete solution? We recommend using a full complete switchbox that includes a new switch box and ensures proper function and safe installation.
Typical cause of failure
• Wear or arcing from repeated on/off cycles, typically leakage
• Poor electrical contact due to misalignment in the housing
• Moisture intrusion, corrosion, or overheating
• Incorrect installation causing physical stress on the switch terminals
Failure symptoms
Part correlation
• Machine does not respond when turned on.
• Intermittent start/stop during use.
• Click is heard when turning knob, but nothing happens.
• Signs of burning or corrosion inside the switch box.
