How to Replace the Trigger Switch on a Cordless Drill

- In this video I demonstrated how I replaced the trigger speed control switch of my Mastercraft 20V Max Li-Ion Cordless Drill, 1/2-in (#054-3118-6) from Canadian Tire. I'm sure the procedure would be very similar for many other Cordless hand drills. The switch that I ordered is a "JV08-1B", which wasn't an exact match, but it was workable. If you are going to attempt this job, I recommend using a higher temperature soldering iron than the 35W one I used.
I hope you enjoyed this video. Please COMMENT and subscribe!
Thanks for watching.
Thank you CJ, very informative. If you can still get a longer life, this is the best option.
Yes totally. Much better than sending this drill to landfill!
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?
I'm with you 100% on not wanting to send these items to landfill. Yes, I had noticed the heat sink was smaller and had considered swapping them but decided not to. That's good information to know for next time!
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.
Absolutely, I completely agree and I wish I had mentioned this benefit in the video!
thats all well and good but finding replacement parts for most things unless they are bog standard parts is next to impossible
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.

Good to know! Do you think the original battery charger will still work if the cells are changed?
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
No problem, good luck!
This is a very helpful video thank you for sharing it 👍
Thanks, glad you found it helpful!
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
I've actually never heard of that trick before. Is the idea that you can essentially dilute the existing solder and therefore give it a lower melting temperature?
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
Good point, the battery packs can be disassembled and the individual cells can be replaced. I wouldn't say that I "like them so much", just that they've been fully adequate for the use that I give them as a hobbyist.
Did you try to replace the switch button from the old button?
Yes, I looked into do that, but the button attaches from the inside and I didn't really want to disassemble the new speed control mechanism. The case is held together with tiny plastic snaps, plus there's no guarantee that the old button will work with the new switch.
@@cjhoyle yes, no point to take the risk. New button will good enough for its whole life. Great job.
Did I see you by the Surveyors monument on Yonge/Yonge Blvd Sunday?
Yup!
This reminds me of modding nerf guns when I was younger
