| HP3466A Damage Switch - Opinion Request |
| (1/2) > >> |
| rfdes:
Hi - I am looking for some suggestions. I have a recently acquired an HP3466 multimeter that I am attempting to get up and running. As no surprise, the ganged push buttons were dirty and needed cleaning. 'Mr 5 Thumbs' managed to damaged the plunger plastic retainer flap as shown in the photos. I've been unsuccessful in finding a replacement switch and now at the point where I want to attempt to repair this the best I can. The plastic is likely polypropylene and adhesives are probably not going to work in this case. So, I was hoping someone who understands the construction of these switches might have a clever idea for implementing a patch for this retainer clip. There is a photo of the broken unit and one of the non-broken switches for comparison. Your thoughts are appreciated. Thanks Jim |

A quick fix could be a suitable hardwood towel cut to fit the switch, perhaps painted or covered in heat-shrink. You need to find a suitable spring or make one from thin piano wire. |

They look alot like C&K F2UEE or F4UEE type switches. I saved some duds I replaced over the years that have good actuators. Looks like you need a new plastic cover on the black one. Hard to tell how many rows of contacts it has but I suppose you could carefully remove the plastic cover on a dud, cut it in half and transplant if you have the patience. If you want a couple of my duds you are welcome to them....actually one of those covers is already separated. |

The second photo looks just like the top of my damaged unit. My unit is a 6PDT unit and your idea of cutting it down and splicing in yours sounds doable. How did you remove the top from the switch in your second photo? They look like they probably slide over the solder lugs and latch in place. Your second photo appears like you may have needed to use some heat to release the latch. I believe I would like to take you up on your offer for the duds. Thanks again. Jim |

Jim Yes I think when I was unsoldering these the heat fouled them up mostly, melting the plastic frames, and loosening up the contacts in the housing. I think you can remove that upper cover carefully with a heat gun on it and a jewlers screwdriver gently prying it off...it didnt take much for that cover to come off in the pic. I am sending you that cover as well. Steve |
