Schneider Electric ZB4 BJ5 Momentary Selector Switch

Schneider Electric ZB4 BJ5 Momentary Selector Switch is a three-position, momentary control device with spring-return action. The spring return means it does not latch; it returns to its default position when the actuator is released, providing a temporary input for the connected circuit. Identified by the model designation ZB4BJ5, this switch is part of Schneider Electric's ZB4 selector family and is designed for reliable operator input in electrical control circuits. With three distinct positions, it enables temporary function selection or signaling without a held position, making it suitable for quick start/stop selections, mode changes, or brief commands in industrial equipment. The compact form factor and robust construction typical of Schneider Electric components support use in control panels and machine interfaces where a repeatable, momentary input is required.
