Does anyone know what the part number and manufacturer s name is for the micro switch in an Auto Loc window crank power window switch.
Autoloc = Hoffman = good luck. (Seach Hoffman here) Having said that, it's probably a common part at an electronics store.
If you need to replace it anyway, just take the assy apart and look for a part number. Or once you have it, you can search for a replacement.
Had a customer that insisted on those in his shortened Chevy wagon they were the biggest pieces of s*** ever
They still sell the pairs of switches on Ebay. I'd agree with take the switch apart and look for part numbers or clean the contacts. I have never had my hands on one but would think that they just have a cam that works a pair of contact switches and if the contacts get burned (like a set of points) they don't work. eBay item number: 164680557286 There are probably 100 listings for them with most of them being the latest back door outlet for Hoffman group junk but that was the top listing on the page.
I don't think that there is a lot to them when you open them up mgtstumpy. From the looks of things they can easily be taken apart and inspected. I'd have to believe that they aren't up to handling the load that an electric window motor can put on a switch that isn't operating though relays. Most of us have been there, done that with an item that has a higher draw than the switch is rated for burning out switches until we wise up and install relays to be operated by the switch.
Not sure if this will help, but I used a Cole Hersee switch and modified the original window crank handles to mount to this switch. Didn't have to use relays. Been in my car for 25 years. DPDT Reversing Mom On/Off/Mom On – Cole Hersee
Look on www.alliedelectronics.com or www.newark.com and search for snap action switches and find a switch like what you want.
Those little microswitches typically are only rated for 5 amps max, a window motor will have way more current inrush than that. So even if you can find a replacement, that probably won't fix the issue. Best bet is finding a switch rated for the duty i.e. a OEM-style window switch from a reputable manufacturer or use relays. You can run those switches that hard, but a shortened service life will be the result, as you have found.
The The micro switch has to be exactly like the ones that I have to fit into the main switch housing.
A tough lesson for me, $150 worth of crank switches there almost completely dysfunctional. Chinese junk from Auto Loc.
Try to match them up in a catalog. It's most likely a double pole double throw micro or snap switch. https://www.globalspec.com/ds/243/areaspec/switch_dpdt
