Sourced and supplied by Al Imran Enterprises, Lahore, Pakistan. The Fuji Electric BH-S1001 is a cam-operated rotary control switch from the B/BH series with automatic-return (S type) action and an S1001 contact arrangement of one NC plus one NO contact. Where ordinary maintained switches stay put, the S type handle springs back to its rest position the instant the operator lets go — exactly what master controller stations, jog-run selectors and multi-step motor switching demand, because a forgotten lever cannot leave a machine in an unintended state. Inside, the polycarbonate housing stacks cam-driven rolling-action contacts whose wiping motion keeps contact faces clean instead of grinding them flat, which is how the series reaches a minimum mechanical life of five million operations and half a million operations under electrical load. Ratings are serious control-panel territory: rated insulation voltage Ui 600 V, continuous current-carrying capacity Ith 20 A, terminals accepting wire up to 5.5 mm² on M4 × 9 screws, dielectric withstand of 2,500 V AC for one minute and impulse withstand of ±7 kV at 1.2/50 µs. Contact resistance stays at or below 50 mΩ over life, keeping control-circuit voltage drop predictable even on long runs. The switch operates from -20 °C to +60 °C and stores from -40 °C to +70 °C, and back-wiring keeps the front of the panel clean. Behind the product stands FUJI ELECTRIC INDUSTRY CO., LTD., the Japanese maker whose B/BH cam switch families have anchored machine control stations for decades. In Pakistan these switches keep textile machinery, presses, packaging machines and machine tools sequenced safely, and when one finally wears out the machine usually waits on that single stack. Al Imran Enterprises stocks and sources genuine Fuji Electric cam switches, verifying contact arrangements and ratings against the original panel documentation before dispatch.
