Main Functions

1. Provide two stable selectable operating states for manual mode switching (Auto/Hand, Run/Stop, Local/Remote etc.)
2. Match stacked auxiliary contact blocks to output separate digital signals to PLC, contactor interlock and indicator circuits
3. Lock each position mechanically to avoid accidental state shift during equipment operation
4. Deliver reliable manual selection for equipment operation mode switching and circuit interlock control

Key Advantages

• Robust all-metal front casing adapts to dusty, humid and oily harsh workshop environments
• Latching structure maintains circuit state without continuous manual holding
• Modular split design, easy to assemble/disassemble contact blocks for on-site wiring modification
• Wide voltage and current compatibility fits all standard industrial low-voltage control circuits
• High mechanical durability reduces replacement frequency under frequent switching cycles
