This ignition switch is an OEM replacement part found near the steering wheel or dashboard in lawn tractors and riding mowers. The switch has four symbols on the top side which indicate its various functions including starting, stopping, running and reversing. The switch works by connecting/disconnecting the circuit between the battery and the ignition system. The switch can fail either from physical damage or faulty electrical wiring. If the ignition switch is no longer working, you will not be able to operate your equipment. To access the faulty switch, first disconnect the battery, and wiring harness. Squeeze the tabs on the sides of the switch and pull it out from its mounting position. Plug the new switch in place and ensure that the tabs are engaged. Finish the repair by reconnecting the wiring harness and battery. If your current key is in good working condition, you can continue to use it. However, if it is not, it is recommended to replace the key at the same time. Each ignition switch is sold individually.
