It is a genuine manufacturer-approved part which is specially designed for use with Poulan, Weed Eater and Husqvarna riding lawn mowers and garden tractors. The purpose of the interlock switch is to act as a safety feature which will shut the engine off if the driver leaves the seat. Unfortunately, over time parts will wear out and it may begin to fail eventually requiring a replacement. Refer to the owners manual and the appropriate diagrams of your model for the correct location and installation of this component. Note, this high-quality plastic body switch is sold individually. You may need a screwdriver and pliers to perform this repair.
