Description
Overview
Trigger switch for large-torque brushless lithium impact wrenches, the JC15-7 carries a 36V DC 20A rating. One switch is supplied, sized for the Dongcheng DCPB998 and ADPB998 auto repair wrenches.
Specifications
- Part number: JC15-7
- Voltage: 36V DC
- Current: 20A
- Role: high-torque cordless wrench trigger
- Fits: Dongcheng DCPB998, ADPB998
Purpose
A high-torque wrench draws far more current than a drill, so its trigger must survive repeated 20A bursts. When it fails the tool looks dead though only the switch has gone, and this restores control.
Applications
- Wheel nut and suspension work
- Chassis and underbody repair
- Heavy vehicle and farm workshops
- Trigger replacement on tired wrenches
- Reconditioning traded-in tools
- Spares for a mobile mechanic kit
How to Use
- Disconnect the battery and let the tool cool.
- Split the clamshell and lift the failed switch clear.
- Compare the old part marking with JC15-7 36V DC 20A.
- Solder the motor and battery leads to the matching terminals.
- Check the trigger springs back freely before the shell goes on.
- Caution: 20A at 36V DC is the ceiling; a higher-voltage pack or a stalled motor is outside this switch.
