I removed the screws attaching the handle and removed one wire at a time from the old switch to the new one. Then put the handle back together.
I just can not believe how fast we got this part. Second time we ordered from this company and they have great service and the right parts for the job. It was easy to do....Thanks a lot.

Weed trimmer erratic power due to loose switch contacts

This was a simple repair. I just had to use a Torx driver to disassemble the trigger housing of the weedwacker (Black and Decker ST4000,) pull the wire terminals off the faulty switch, replace them on the new switch, install and close up the housing. Easy, peasy.

Parts arrived in the mail - accuracy of the order was spot on!
Downloaded the parts diagram for the trimmer....on the internet

Removed screws from handle assembly. Took one terminal at a time from the old switch and put it in the same place on the new switch. Put housing back together. I then pulled the defective lever out of the spool holder, then pressed the new one back in.

Both items installed without any problems and the trimmer worked as good as new - saving me the expense of replacing it with a new trimmer.

Much appreciation and thanks!!

What I needed, unavailable locally

While I have not had a chance to reassemble the unit complete with the new switch, the part you sent appears to be exactly what I needed.

Guest - April 25, 2023 Verified Purchase

Longer than expected

Took longer to receive item than advertised probably due to US postal service these days. Switch fixed the problem. Thanks

Replacement switch for my "weed eater".

The switch was purchased on line, and recieved promptly in great condition because of the package system. The switch was easy to replace and straight forward. I enjoy this particular B/D product and plan on keeping it in working condition as long as possible...

Perfect replacement switch to regain use of my weed wacker

Part was the exact replacement switch. Delivery was fast, allowing me to leave the wacker on the work bench with the case opened for the switch to be installed. New life to a tool with plenty of service left in it. Price beats the cost of a new weed wacker!
