Product Overview
The control is used where an operator needs a positive emergency-stop input. Research for the XB4BT42 configuration identifies a normally-closed contact, so matching the contact arrangement and panel geometry is important when replacing a switch in JLG control boxes.
The original Schneider Harmony XB4BT42 specification is discontinued, so replacement listings may supply an equivalent-format device rather than a Schneider-branded part.
Key Features & Performance
- Machine-control input: Provides the electrical state change used by the machine's start, safety or emergency-control circuit.
- Exact configuration matters: Contact arrangement, connector/terminals, actuator style and mounting must match the original switch.
- Functional testing required: After replacement, verify that the associated control or safety circuit changes state correctly.
- Product-specific note: The original Schneider Harmony XB4BT42 specification is discontinued, so replacement listings may supply an equivalent-format device rather than a Schneider-branded part.
Technical Specifications

Frequently Asked Questions
How do I confirm this is the correct part?
Confirm panel-hole size, contact arrangement, terminal style and machine schematic before replacing an emergency-stop device.
Is this an OEM part?
Unless the listing is explicitly identified as genuine/OEM in the product data, treat it as a replacement component. Use the verified reference numbers, equipment application and physical configuration above to match your original part.
What should I check before installation?
E-stop circuits are safety-critical; function and contact state should be tested after installation.
Fitment note: Equipment manufacturers may use different components within the same model family based on engine, serial number or production date. Confirm the original part number and machine/engine details before ordering.
