These are the brushes: http://www.littletyke.myzen.co.uk/brushes.jpg
And the brush holders/commutator: http://www.littletyke.myzen.co.uk/brush_holders_and_commutator.jpg
And finally the jigsaw's type plate: http://www.littletyke.myzen.co.uk/jigsaw_type_plate.jpg
I've found a company that supplies brushes purporting to be suitable for this model, but they look different: http://www.powertoolcentre.co.uk/Product/1336__dot__2/AEG-Atlas-Copco-240v-Carbon-Brush-Fits-STSE60-STPE60-STSZ350-VS350-HES40-50-60
The replacement brushes have caps on the ends of the springs, whereas the brushes in my jigsaw just have the springs without caps or wires.
Are these replacements suitable? Is it a newer design?
Or is there a "universal" brush type I could use? (Maybe re-use the old springs.)
Finally, comments about the state of the commutator would be welcome.
