The HE3B-M2PB is a 16 mm diameter 3-position redundant contact enabling switch with black rubber cover designed for manual robotic control and safety-critical applications. It features snap-acting contacts between positions 1 and 2, multiple contacts for enhanced reliability, and a non-reclosing design that prevents contacts from re-closing when released from the ON position (compliant with IEC 60204-1). The switch operates at a rated insulation voltage of 125 V with a thermal current of 3 A, supports AC resistive loads up to 1 A at 125 V and inductive loads up to 0.7 A, and achieves an electrical life of 100,000 operations minimum at rated load with a mechanical life of 1,000,000 operations. It is rated for operating temperatures from -25 to +60 °C, storage temperatures from -40 to +80 °C, and provides IP65 protection with the rubber cover. This enabling switch is ideal for emergency stop systems, robotic control panels, and industrial machinery where personnel safety and reliable manual control are paramount.
