Ignition switch (Part #90024695) used on Kalmar Ottawa / Ottawa terminal tractors and yard trucks. It’s the factory-specified electrical switch that powers the truck’s electrical system and allows the engine to start when the key is turned. If this part fails, the truck may not start or lose electrical power intermittently, leading to unexpected shutdowns, inability to engage accessories, or being stranded in the yard. Early signs of failure can include no response when turning the key, flickering dashboard lights, or difficulty engaging the starter.
