Genuine Husqvarna replacement spring used in button mechanisms on compatible Automower® equipment. Depending on the model, it is fitted beneath the charging station’s cover-release button or within the mower’s STOP-button assembly.
Replace a damaged or missing spring to restore the mechanism’s intended return action.
Common Reasons for Replacement
Broken or deformed spring: Replace if inspection identifies damage.
Insufficient return action: Replacement may be needed if the spring no longer returns the button correctly.
Missing spring: Restore the mechanism if the spring was lost during dismantling or servicing.
A sticking button can also result from dirt, incorrect assembly or damage to surrounding components. Inspect the complete mechanism before replacing the spring.

Important Notes
The same spring has different applications across models. It is not a universal replacement for every Automower® STOP button.
For charging station repairs, disconnect mains power before servicing. For mower repairs, switch the mower off and follow the model’s service procedure.
If servicing a STOP-button mechanism, confirm correct button operation before returning the mower to use.
