MAJSW2PR‑L137‑0300‑01 Pull‑Chain Switch

The MAJSW2PR‑L137‑0300‑01 is a rugged, single‑pole, double‑throw pull‑chain switch designed for use in lighting, fan control, and industrial equipment. It offers reliable mechanical switching with a durable metal housing and chain actuator, making it ideal for both on‑wall mounting and inline installations in electrical panels or machinery.

Single‑Pole Double‑Throw (SPDT) Contact: Enables convenient switching between two circuits (e.g., light on/off/fan enable), providing flexibility in mechanical control systems.

Pull‑Chain Actuation: Metal pull‑chain offers tactile feedback and clear position indication, simplifying user interaction in overhead or hard‑to‑reach locations.

Heavy‑Duty Metal Housing: Constructed from die‑cast or stamped metal, delivering high mechanical resilience for industrial and high‑use environments.

Compact Inline Format: Slim profile suitable for panel, enclosure, or wall mount installations, adaptable across electrical systems.

Current & Voltage Rating: Typically rated for 5 A at 125 VAC (confirm with datasheet), making it suitable for lighting circuits, small fans, and accessory loads.

Long Mechanical Life: Designed for at least 10,000 pull cycles, ensuring longevity in frequent‑use scenarios.

Easy Installation
Includes mounting flange or standard panel cut‑out compatibility, speeding integration into custom setups.
