Poulan 503718201  Ignition Switch, Start/Stop

An Ignition Switch in the control system of a model activates the main electrical systems. Signs of a faulty ignition switch include the engine dying, not starting, and disruption of power to the equipment electronics. Worn ignition switch contacts, overheating, or broken springs all can cause the ignition switch to fail. It is recommended to replace ignition switches from the OEM manufacturer, as the wrong switch can damage the electrical and ignition components of the machine.
