Remove the batteries and lift the two straps with a flat screwdriver. Pull the straps out.

This is the most crucial part. Do NOT try to release the latches at the front. Insert a small screwdriver at the positions indicated in the back near the "belt hinges" to flex the rear part of the case back and free the latches of the inner part.

If all went well, the inner part should come out. In my case the push button fell into its pieces as well. You see the rubber layer and sheet metal clip of the button in the orange back of the outer knob.
-
The push button itself is a smd device of 6mm x 6mm and about 3.1mm height. The best thing would be to replace it. If you can get a spare part and can solder these tiny pads go for it. I just cleaned the dome spring with a piece of paper and reassembled it. Make sure you place the concave side of the dome spring on the three connectors.
-
Before reassembly try to insert batteries and verify that connecting the middle pole of the button to one of the outer ones switches the light on. Dont look straight into the LEDs, they're very bright!

With minor modification this guide is suitable for other Petzl torches.
How do you strap the headband after taking it off…silly question but any info would be helpful
I have two of these units, and was able to get them up and running again thanks to your tutorial. The contact needed a little sanding, and now they work again like they should. Thank you!
This guide fixed a well-used, 14 year old, three LED E47 Tikka. It had a slide switch that needed fiddling with. Thanks.
