Common Questions: Is this switch compatible with non-Williams blowers? The P320911A switch is precision-engineered for Williams Blower 2102 and 2901 models. Verify the MFR # P320911A before installation to ensure electrical and mechanical matching with your specific fan speed regulation unit. Can this switch be used to replace a single-speed toggle? This part is specifically a two-speed switch. It should only be used in systems designed for Hi-Lo fan speed control to avoid wiring complications or improper motor sequencing. Does this include the wiring harness? The P320911A is the standalone speed selector switch. Existing wiring or the P320912 wire bridle should be inspected for continuity during the replacement process.
