Harmar Platform Lift Gate Suns Interlock w/ Pigtail

High-duty solenoid safety interlock switch for platform lift gate and landing interlock applications among select Harmar Summit wheelchair lifts.

A rugged safety interlock designed for use in vertical platform lifts and elevator gate systems, this solenoid-based safety switch ensures that lift movement is permitted only when gates or access panels are secure and correctly positioned. Engineered around the SS6291 series from Suns, it provides strong key holding force with multiple voltage options and durable materials suited to the demands of lift access safety systems. Commonly found in Harmar platform lifts such as the VPL-400X as an upper landing interlock or platform gate lock switch, this component integrates into safety circuits to help prevent operation when access barriers are open. 

• Solenoid interlock safety switch suited for elevator and platform lift applications
• Zinc-die-cast body and head for durability in industrial environments
• Designed to secure gates or access doors before allowing lift operation
• Compatible with multiple control voltages (e.g., 24 VAC/DC, 120 VAC, 240 VAC)
• Key-operated actuation for positive mechanical locking feedback
• Commonly used as upper landing interlock or platform gate lock switch on Harmar VPL-series lifts

This switch is engineered for reliable mechanical and electrical engagement where access control and safety interlocking are required. Suitable for replacement or retrofit in compatible lift systems that rely on solenoid-driven interlock logic, its robust build helps withstand frequent cycles typical of residential and light commercial platform lift use.

As with any safety-critical component, installation should be carried out by qualified technicians familiar with platform lift control systems and applicable codes; proper installation helps maintain designed safety performance.
