Key Features
- OEM Electrical Specification — manufactured to Husqvarna's exact actuation force and contact ratings, ensuring the switch triggers at the correct point in the control circuit rather than at an approximated threshold.
- Drop-In Wiring and Mounting Fit — matches the original connector terminals and mounting footprint, so this switch seats and wires directly into the existing housing without modification.
- Broad Machine Compatibility — confirmed for the PG400 floor grinder and CG200 floor scarifier, covering both grinding and scarifying applications in Husqvarna's surface preparation lineup.
- Protects Control Circuit Integrity — a correctly functioning micro switch delivers clean, decisive on/off signals that keep the machine's control system responding accurately; a worn or intermittent switch can cause erratic behavior or failure to start.
- Electrical Safety Compliance — as an OEM component, this switch meets the original design intent for the machine's safety interlock and control circuits, which is critical for operator protection on powered surface prep equipment.
A micro switch is a precision snap-action electrical switch that opens or closes a circuit with a very small physical movement — typically activated by a lever, plunger, or cam within the machine's control or safety interlock system. On floor grinders and scarifiers, micro switches are commonly used in operator controls, guard positions, and safety cutoffs to ensure the machine only runs under the correct conditions. When a micro switch fails — through worn contacts, broken actuation arms, or contamination — it can cause intermittent operation, prevent the machine from starting, or defeat a safety interlock, making prompt replacement essential for both performance and operator safety.
