Hoạt độngPower Tool Trigger Switch Variable Speed
Marquardt trigger switch for power tools — variable speed control.
Ứng Dụng Phổ Biến
The trigger in your cordless drill. Marquardt makes the trigger switches inside most Bosch, Metabo, and Hilti power tools. Variable speed via analog position sensing — squeeze harder for faster. Reverse switch integrated. When your drill trigger feels precise and responsive, its probably a Marquardt inside.

Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Khắc phục sự cố
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
