Guide :Camping, Backpacking & Hiking : Myolite 3 Hybrid Headlamp

My petzyl myolite seems only to come on when the wiring is facing downwards. I suspect a faulty wire but am unsure how to take it apart without damaging the head torch.

How to replace witch assembly in rechargeable Maglite?


1st, remove the battery via the **** end of the barrel. 2nd, carefully remove the little RUBBER CUP that covers the depression off/on switch. Gently maneuver it out by lifting the edge of it then pulling it out. Do not cut or puncture it. This little rubber cup keeps water and dirt out of the switch. 3rd, Remove the HEAD (light assembly) off where the charging rings are, just behind the switch. Hold the barrel with one hand and with the other twist the head until it begins to unscrew from the barrel and until it is free. Upon completion of this step, set the barrel aside. If you have a digital camera you can photograph each step of this so that when you reassemble, you can simply refer to the photos for reverse order assembly. 4th, Unscrew the LENS CAP and set it aside. At first it may seem as if it is not unscrewing but keep going as it will come off. Upon completion, set the lens cap aside. 5th, Hold the BULB with a tissue and pull straight out with out twisting. Do not hold these types of bulbs with your bare hands as the moisture and oils of your skin can damage the bulb when the switch is turned on. Upon completion secure the bulb and set it aside. 6th, You will now be left holding the BEAM ADJUSTMENT HEAD which also contains the OFF/ON SWITCH. 7th, Firmly hold the ADJUSTMENT HEAD (the large portion) in one hand, then place the small end in the palm of your other hand and push the small portion through and out of the large portion. Set the head aside. You will now be holding the short barrel which contains the bulb holder and the OFF/ON SWITCH. 8th, Now look at the OFF/ON SWITCH. You will see a white plastic cylinder looking up at you. When you push it down you will hear and feel it 'click as it is engaged in the 'on' position. This and the assembly it is contained with-in must now be removed from the short barrel containing it. *CAUTION* When you finally ( In step #9 below) remove the SWITCH from the short barrel, the assembly containing the switch itself will want to 'spring' apart into two halves because it is under slight pressure due to the spring which puts tention on the OFF/ON button. Hold it firmly until you have it completly removed from the short barrel. Pay attention as you do this so that you can remember how to put it back together at reassembly time. 9th, Using a small common tip screw driver, depress the WHITE plastic OFF/ON button as far down as it will go. While you are holding it down with the screwdirver use the thumb of your other hand and push against the BULB HOLDER, this will cause the SWITCH assembly to move forward about 1/4inch and to the point where you can release pressure on the switch with the screwdriver. At this point DO NOT continue pushing. 10th, look down into the barrel where the white plastic switch is that you had depressed in step # 9. You will see a BLACK plastic housing which holds the WHITE OFF/ON SWITCH. Using your small blade screwdriver, slide it behind the BLACK plastic housing and gently apply a prying pressure which will force that housing containing the SWITCH assembly, to move forward and exit the short barrel containing all of this. REMEMBER! It is at THIS point that the two-part housing holding the switch assembly will want to 'spring' apart. Pay attention and go slowly. When you reassemble this part of the flashlight, know that in order for the switch assembly to go back into the short barrel the WHITE PLASTIC OFF/ON button has to be DEPRESSED, do it with the screwdriver, enough to clear the interior side of the barrel. Depress it and gently push the assembly back into the barrel until it is back where it began. Be sure to line up the male notch on the exterior of the switch housing with the female grove of the interior of the small barrel. If you have the notch lined up and the switch button depressed all the way it will slip right into place with a happy clicking sound. Upon completion of that step, reassemble the rest of the components in reverse order. There you have it. Good luck. :)

Makita ML 140 torch. Old battery would not hold a charge as it was very old. Torch works well with a new Makita PA14 battery. But the handle gets quite hot and I need to dismantle it to find the problem. One would not expect heat from the handle but rather from the head. I have undone the screws but the swivel part also has to be removed for access. What is correct procedure? I am radio technician Thanks, Dave B.


Remove the lens, and bulb holder. look down into the cavity, and you will be able to see the spring loaded pivots. Find sonething narrow to push them in with, so that you can remove the head. here is my fix (with photos) for the 18v version
