    I'm kinda new here in the forum. I've been signed up for a minute but haven't posted till now. there are several members whose posts have really helped me through some troubleshooting and solutions. Especially with the 4WD system. Special Thanks to the following members: SIXWEEDS, HUNTERTN, V@PORS, FRODOTX, PAPASMURF, & ALL THE OTHER MEMBERS whose posts have helped me with several issues since I started using this sight. When I get a chance to go through all my notes I'll give a shout out to the rest of you guys (there's a few).What's weird is I used to work for one of Toyota's Motor Manufacturing Plants. Lol. More on that later, possibly. Lol. My issue is: Micro switches finding them here in the U.S. I found the maker (MIK ELECTRONIC PART#: MPU12491MMB0) If anyone wants to know the info). They're a Japan based company with no offices or distribution centers in the U.S. that I can find. I'm just looking for the parts themselves, if anyone has any extras to sell I need all three of the gray w/ black cover ones. One of them I was cleaning I had the contacts inside on a pair of tweezers and they flew out and now I can't find it. It's somewhere in my carpet or in some boxes stacked nearby in my work room. I've looked several times and tom no avail, I'll probably find it after all is said and done, you guys know how that goes, right? LOL. BTW they're supposed to be self-cleaning, I've found out, which might explain the black residue inside of them that some of the members in SIXWEEDS post have mentioned. As for the other 2 that I need, to save on searching again when I clean my other actuators and one is bad or I lose one God forbid. I'll have it on hand. If I end up not using the 2 others I'll pay the favor forward to any other member who may be in need of one. So if any members can help me drum up the three I would be grateful for it. THANKS AGAIN. email is xmfman@gmail.com you can holler at me here or there or both haha.

    After hours wading thru every resource I could, and not finding a single mention of this switch being a problem for others, I have 100% diagnosed this as my 2008 Sequoia's problem as well. I just cannot accept buying an entire new actuator for a microswitch! I also saw on digikey someone requested a suitable match request to this switch, but they responded there is nothing they could find. https://forum.digikey.com/t/need-mpu12491mmb0-push-lever-micro-switch-dc-v/51774
    I am hoping to find a used actuator with other major problems to farm a switch from.
