How to Replace the Trigger Switch on a Cordless Drill 

I keep repairing my old appliances and tools. It's worthwhile because the newer stuff (tools, appliances) is more cheaply made. The replacement parts are cheap and all it takes is a little bit of time. It also keeps garbage out of the land-fills. Repairing old appliances is the ultimate recycling.

Well worth doing CJ, Especially at that price. For me the bigger deal is keeping the batteries and old tool out of landfill or "recycling", even recycling uses a huge amount of energy. I noticed that the heatsink on the new switch is smaller than the old. It may be worth going back in there and seeing if you can exchange the heatsinks. The way these switches work to reduce the speed is they turn the power off and on very quickly, so unless you are off or on full the switch has to dissipate heat to do this. It might also do it all the time when using the screwdriving feature. If you do decide to do this add some heat transfer compound between the transistor or mosfet and the heatsink. I have seen some washing machines where there was no compound between the triac (transistor) and heatsink and guess what failed?

Thank you CJ, very informative. If you can still get a longer life, this is the best option.

A very well produced video. I have a Kobalt 24V impact driver that needs switch replacement. Im assuming its the same as the drill. Thanks a bunch!!! Bob

When your batteries start to lose power or actually 'DIE', I would suggest refurbishing and use the 18650-35e or equivalent cell which weighs 46grams+ each and are 3500mAh which should upgrade your battery to double capacity. 20V Max is just a 18volt battery which is actually 21.2+ volts using the actual the No-Load rating.The individual cells will charge up to 4.25 - 4.27 volts approximately and multiplied by Configuration 5S x 2P (5 cells x 4.27V = 21.2V+ approximately). [5S is 5 cells row in series and 2P is 2 rows in parallel] This is much cheaper option if your hand tools are still performing satisfactorily. Les D

This is a very helpful video thank you for sharing it 👍

Good video. Informative and to the point. You could teach so many other youtubers. Well done.

5:40 you should add some leaded solder to soften the original lead-free solder, making easier to remove

you can fix your batteries if you know to replace then you wouldn't need to thin k about getting rid of your drills if like them so much

Did I see you by the Surveyors monument on Yonge/Yonge Blvd Sunday?

Did you try to replace the switch button from the old button?

This reminds me of modding nerf guns when I was younger
