Product Description
The BG 1115-510008-00 switch is a high-current emergency power cut-off switch designed for Big Joe’s S22 electric straddle stacker. Pressing this red emergency stop button immediately cuts all battery power, halting the truck’s lifting, lowering, and driving functions for safety. This rugged switch is rated for 48 volts and 125 amps, matching the electrical system of Big Joe pallet trucks. It directly replaces Big Joe OEM part number 1115-510008-00, and is compatible with the S22 and other Big Joe models like the E30, EZ30, D40, and EZ40.
The replacement assembly includes the large red mushroom push-button and internal switch contacts, ready for installation. Built with a durable plastic housing and heavy-duty copper contacts, it uses screw terminal connections for secure wiring.

Frequently Asked Questions
Q: What does the emergency disconnect switch do on a Big Joe S22?
A: The emergency disconnect instantly cuts battery power, stopping all driving, lifting, and lowering functions. Pressing the red button halts the truck completely to prevent accidents. The S22 remains off until reset, ensuring operators can stop the machine quickly and safely in emergencies.
Q: Is this switch an OEM Big Joe part or an aftermarket component?
A: This switch is an aftermarket replacement built to OEM specifications. It matches the original’s performance and fit. Its a cost-effective, high-quality alternative, ensuring safe and reliable operation.
Q: How do I reset the switch after it’s been pressed in an emergency?
A: The switch latches when pressed. Reset it by twisting the red button clockwise until it pops back out. Once reset, battery power is restored and the key switch can be used. Always address the emergency cause before reactivating the truck for safe operation.
Q: Will pressing the emergency stop damage the electrical system or battery?
A: No. The switch is designed to safely interrupt high current flow without harm. However, it’s not meant for daily shutdowns—use the key switch instead. Frequent, unnecessary E-stop use can cause premature wear of internal contacts.
Q: Why is an emergency disconnect switch important on a pallet stacker?
A: It’s a critical safety feature. If the operator loses control or someone is endangered, pressing the switch stops all movement instantly. This prevents accidents, injuries, and equipment damage. Operating without a working emergency stop is unsafe and violates safety standards, making proper maintenance essential.
