Introduction

Honeywell's MICRO SWITCH GLA limit switch series is designed to the global EN50041 standard, making it ideal for worldwide applications. The modular design (head/actuator, body, and contact block) enables rapid response to customer application requirements. The switch's rugged die-cast metal housing suits both indoor and outdoor applications requiring IP or NEMA protection ratings. Normally closed snap-action and normally closed slow-action contacts are of the positive-opening type.
