I've got a Dewalt like that - bought it in the USA for a job out there in around 2002 ish - it came back with me and occasionaly runs from a 110 box - in fact I'm just thinking if I actually know where it is . . . I really like the switch for the very reason the OP now dislikes his as it doesn't - as soon as you let go, it switches off.Milwaukee m18 - go to grinder. It’s the mutts. Paddle switch. They are the new thing for RAMS apparently. Absolute pig till you’re used to it. Once you are it’s hard to go back to a normal switch
