Allen-Bradley 836-A105 Pressure Switch

Allen-Bradley 836-A105A pressure switch is a Bulletin 836 Series pressure control device designed to monitor pressure and actuate electrical circuits at a preset setpoint. It is rated for up to 600 V AC and a maximum load of 5 A, making it suitable for controlling relays, alarms, or interlocks in industrial equipment. As part of the 836 Pressure Controls family, this mechanically actuated switch provides robust, reliable pressure sensing for automation and safety circuits in manufacturing and processing environments. The switch operates by sensing pressure through an internal mechanism and changing its electrical contacts when the target pressure is reached, offering a straightforward interface for control systems without requiring complex electronics. Typical uses include integrating with industrial automation circuits where a proven, hard-wired pressure-triggered switch is preferred for dependable operation in demanding applications.
