Allen-Bradley 1492-CB3-G040 Pushbutton Contact Block

The Allen-Bradley 1492-CB3-G040 Pushbutton Contact Block is a modular accessory designed to attach to compatible 1492-series pushbuttons in industrial control panels, expanding the number of electrical contacts available from a single operator. It enables additional switching points for auxiliary circuits, allowing more complex control logic without altering the primary pushbutton assembly. As part of the 1492 family, this block is built to the rugged standards of Allen-Bradley components and is intended for use in demanding industrial environments where reliability and straightforward maintenance matter. This contact block supports standard field mounting practices for pushbutton stations and integrates with accompanying button heads and enclosures to streamline control panel layouts. Typical applications include start/stop circuits, interlocks, signaling paths, and other auxiliary control functions in machine automation, where operators need dependable, compact expansion of a pushbutton's switching capability. By adding a CB3-G040 block, technicians can tailor a control station to the exact logic of a given machine, reducing wiring complexity and keeping maintenance tasks efficient.
