JCBD-CD18C trigger switch

SOURCE: Hammer drill quit

If it is an 1199, forget it. Replace the brushes and do NOT use for hammering. It is a design problem. My unit was repaired 4 times and hammered about 5 holes each time before same failure.

Before you look for a replacement of switch try first to checked the connections of switch if it is OK,then try to cleaned the contact with it.,If you are know how to used a tester try to checked the continuity of the switch, by placing the test probe of the tester to the 2 wire of the switch then from the tester select sound continuity,(one test probe to one wire) it should hear a sound from the tester,it means the the switch is good. Hope this simple solution could help to solve your problem. Don' t forget to rate me up sir/madam.Thanks.

faltering on a slide contact on electric field or switch, but in most cases dirth (dust) in carbonbrushes can be hanging somewhat in one or both brushholders.
Or a problem in the trigger switch itself dust and dirth have almost the highest priority in case of faltering by clamping carbon brushes.
