Frequently Asked Questions
Q: What does the YL 50649900 Key Switch control?
A: The YL 50649900 is the ignition or main power key switch for Yale electric lift trucks. It connects and disconnects the battery from the trucks electrical system and controller, enabling safe equipment startup and shutdown.
Q: Which Yale electric trucks use the YL 50649900?
A: This key switch fits Yale electric pallet jacks and lift trucks within specific model ranges and voltages. Confirm your truck serial number and electrical specifications match before ordering, as key switches vary by truck type.
Q: What are signs of a failing key switch?
A: A failing key switch may cause the truck to not power on, lose power unexpectedly, or remain powered when the key is removed. Intermittent electrical symptoms or the need to jiggle the key also indicate switch wear.
Q: What is the typical lifespan of a key switch?
A: Key switches typically last 5 to 7 years under normal use. Heavy use, frequent on-off cycling, or moisture exposure shortens lifespan. Switches should be replaced if they become unreliable or fail to hold position.
