SWITCH, DIRECTIONAL CONTROL
Frequently Asked Questions
Q: What does the YL 0136151FA directional control switch do?
A: The YL 0136151FA is a proportional directional control switch for Yale electric ride-on pallet jacks and platform trucks. It provides smooth, variable forward and reverse speed control, allowing operators to move the truck at any speed from crawl to maximum without sudden acceleration. It does not control lift or lower functions.
Q: Which Yale truck models are compatible with the YL 0136151FA?
A: The YL 0136151FA is used on Yale electric walkie-rider and rider pallet jacks from 2011 through 2019, including MP50, LP50, and specialized warehouse models. Confirm your truck serial number and control panel layout match this part number. This switch is Yale-specific and does not fit Raymond, Toyota, Crown, or Hyster equipment.
Q: How does the YL 0136151FA provide variable speed control?
A: The YL 0136151FA uses a variable resistor inside the switch handle that changes the signal voltage sent to the drive controller as the operator increases or decreases pressure on the handle. This allows smooth acceleration from 0 to maximum speed without the jerky start-stop behavior of simple on-off switches. It requires a proportional-control motor controller to function properly.
Q: What is the operating voltage for the YL 0136151FA?
A: The YL 0136151FA operates on 24-volt DC power and outputs a proportional signal ranging from 0 to 24 volts to the drive controller. Do not use this switch on 12-volt or 48-volt systems. Incorrect voltage will cause drive-system failure and prevent the truck from moving forward or backward.
Q: How long does the YL 0136151FA switch typically last?
A: The YL 0136151FA switch assembly typically lasts 6 to 11 years in standard warehouse service, with slightly shorter life in cold-storage environments. The variable resistor inside the switch can wear faster than fixed-contact switches if exposed to frequent moisture or temperature swings. Replace when the truck hesitates to accelerate or when speed response becomes inconsistent.
Q: What failure signs mean the YL 0136151FA needs replacement?
A: Replace the YL 0136151FA if the truck does not move forward or backward, if the truck moves at full speed only (no variable speed control), if movement is jerky or stalls partway through motion, or if the switch handle is cracked or stuck. Internal resistor failure can also cause the truck to move unpredictably. Replace the complete switch assembly when any fault occurs.
