Description
Overview:
The Anti-Start Switch for Husqvarna R111B and R112C ride-on mowers is a genuine Husqvarna safety interlock component designed to stop the engine from cranking unless the correct operating conditions are met. Built with a durable plastic housing and plated metal contacts, it provides reliable switching in outdoor use. As a direct-fit replacement (MPN 506 90 96-01 / 506909601), it maintains the mower's original safety logic without modification. Fitted within the start-prevention circuit, it helps prevent unauthorised or unsafe starts and supports compliance with safety procedures on domestic and professional Rider machines. Use this part to replace a worn, damaged, or intermittent switch and restore dependable starting control on compatible Husqvarna Rider models.
Key Features:

- Restores the anti-start/interlock function to prevent unintended engine cranking
- Robust polymer body with metal terminals for long service life in outdoor conditions

- Clearly identified as MPN 506 90 96-01 (506909601) for easy cross-reference
- Helpful when diagnosing "no-crank" faults caused by a failed safety switch
Typical Applications:
