Switch 110771-74BJ9GT – Roller Limit Switch, NO/NC Gold Contacts

🔹 Product Overview: Safety Interlock and Position Sensing
The Limit Switch with part number 110771-74BJ9GT (and its predecessor 110771-74BJ9) is a highly reliable electro-mechanical device manufactured for Genie Aerial Work Platforms (AWP).
This switch is designed for position sensing and safety interlock within the machine’s control system. The key technical specifications are:
- Roller Actuator: Features a mechanical roller arm actuator, which makes physical contact with moving parts (such as a boom section, turntable, or control lever) to actuate the switch contacts.
- NO/NC Contacts: The switch includes both Normally Open (NO) and Normally Closed (NC) contacts, providing flexibility for safety and control circuits. The use of “GOLD” contacts indicates a design intended for low-voltage/low-current switching, commonly found in electronic control circuits (like PLCs or control modules) where reliability and resistance to corrosion are paramount.
The 110771-74BJ9GT is crucial for ensuring that the Genie lift operates within pre-defined safe limits, detecting the end-of-travel for various boom or chassis movements, or verifying the position of safety guards or gates.
🔹 Key Features & Benefits
✅ Precision Sensing: Features a Roller Actuator ideal for precision sensing of boom position or travel limits.
✅ High Reliability: “GOLD” contacts ensure superior conductivity and long-term reliability in low-current electronic safety circuits.
✅ Dual Circuit Function: Provides both Normally Open (NO) and Normally Closed (NC) contacts for versatile wiring in safety and control loops.
✅ Safety Critical: Essential component for interlocks on boom extend/retract, swing, or chassis controls.
✅ Direct OEM Cross-Reference: Exact match for Genie part numbers 110771-74BJ9GT and 110771-74BJ9.
