laytonl Posted December 20, 2020 Report Share Posted December 20, 2020 Sometimes the switches just need cleaning with electroclean. Lee Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted December 20, 2020 Report Share Posted December 20, 2020 I think it is V3L-3 It is in the parts manual. Quote Link to comment Share on other sites More sharing options...
EricJ Posted December 20, 2020 Report Share Posted December 20, 2020 Yes, V3L-3, and, yes, drown it in contact cleaner first. Those switches can be hard to find, but if you're patient they show up fairly cheap on ebay or elsewhere from time to time. If the contact cleaner revives it, I'd still start looking for replacements. And have some more of the little screws handy, they're a b*tch to get back in to hold the wires. 1 Quote Link to comment Share on other sites More sharing options...
larryb Posted December 20, 2020 Report Share Posted December 20, 2020 Actually I believe the relays may be more problematic than the switches. There are numerous threads here on flap relays. I have had two failures of relays. In my opinion as an electrical engineer there are a couple of shortcomings in the relay implementation.

larryb Posted December 20, 2020 Report Share Posted December 20, 2020 One more thing, if it is the microswitches, an alternate to V3L-3 is V3-1 with a JV-5 actuator. Both of these options are listed in my IPC. You can buy the V3-1 and a JV-5 actuator for less than $30 total. https://www.mouser.com/ProductDetail/Honeywell/V3-1/?qs=0x4sLrpp94JcOlsy%2BnfV2g%3D%3D https://www.mouser.com/ProductDetail/Honeywell/JV-5/?qs=0x4sLrpp94L5KVBAkxWreg%3D%3D and if you really really want the V3L-3 you can find it here for about $100 https://www.mouser.com/ProductDetail/Honeywell/V3L-3/?qs=JT4vHv%2B%2Bx3RbPn2gKwjHYg%3D%3D 2 1 Quote Link to comment Share on other sites More sharing options...
