nebojsa Posted June 3, 2021 Report Share Posted June 3, 2021 I have a old Milwaukee hammer/drill that still works great, but the trigger switch is gone. The original information on the side is gone, but where the battery slides in, it shows 0624-9. Can't find much about the drill on the web, and the only switch that i did find, that even looks close to mine ,is for a another model. The switch part is Milwaukee 22-66-0605 https://www.ebay.ca/itm/182242706407?hash=item2a6e8303e7:g:6ZsAAOSwAYtWOB5b Anybody have any advice Here are some pictures of the old drill Quote Link to comment Share on other sites More sharing options...
fm2176 Posted June 3, 2021 Report Share Posted June 3, 2021 I did a quick search, and you can find the switch here as well: https://www.ereplacementparts.com/milwaukee-062420-ser-321b-18v-1234-cordless-hammer-drill-parts-c-131_5138_16243.html The price is actually a little higher than the eBay listing you found, but you can at least confirm that it fits both versions of the 0624 drill, which I'm pretty certain is what you have, based on the label as well as comparing your photos to some other listings. The "-20" on Milwaukee tool listings denotes a bare tool, with "-21" and "-22" used for 1 and 2 battery kits, respectively. The "-9" on yours is probably just part of an older Milwaukee numbering convention. 1 Quote Link to comment Share on other sites More sharing options...
wingless Posted June 4, 2021 Report Share Posted June 4, 2021 Note that to limit / prevent future failures of the integrated regulator, always operate the tool in full throttle in high load conditions. A partial throttle under high / heavy load makes lots of heat in that burned up switch regulator. 1 Quote Link to comment Share on other sites More sharing options...
