 Where in the world is that part you need? What part are we looking for this week? So what the part I was looking for this week is White angle tactile switch that's easy for people not machines. I don't have any other Acrylic knowing, you know enclosure. I want people to be able to press these buttons very easily So they're right angle surface mount tactile buttons. So let's How do we find them? Well, we're gonna have to wait 72 days 13 hours 41 minutes while we wait Let's go to dig a key. Okay, so Let's look for these tactile buttons. So when you look for Because something is simple, you know, the more popular something is the more names there are for it So you can call them tactile switches tactile buttons or push buttons. There's like so many names I I just use the term tactile switch Even though technically most people think a switch is something that switches on or off and a button is something you press I know I know I know but this is what we call it Current flows from positive to negative electrons move from negative to positive These things are called tactile switches. It's just like life. We should have to deal with it Push button switches, which is what you think you would be calling it. These I think are more like larger Buttons that are like they have like a top to them I don't know the like real reason why some things are Push buttons some are tactile. Maybe there's like a spring contact because I think some of these have like a tactile Contact in the my attack that contact. It's like a this dome and you press the dome and then the dome makes the connection for you Mysteries, but anyways what we want is tactile switches And there's there's a lot there's not like infinite, but there's there's quite a few there's about 5,000 different ones and on one hand There's a lot of different switches on the other hand there aren't really that many switches like a lot of switches are kind of the same So like these are six millimeter tactile switches and you see ones from C and K and ones from e-switch and this is another one from APM and you're looking at these and you're like These kind of look the same. Yeah, they look the same. You know tactile switches have a lot of common form factors that were You know, maybe Omron eventually originally came up with them. Maybe like I don't even know like 3m who knows some company came up with these and they just become generous eyes to the point where If you need a switch chances are you don't need to get it from there It's probably not going to be like there's only one place to get it It's probably like a generic component, which is really good because the switches that you pick You don't want to Like it's like a resistor, you know, you need a five or one percent resistor from everywhere It doesn't matter whether it's from Yagi or Panasonic or like Venkel or whoever Similar switches you don't want you don't have to be stuck with one source of switches I have and I have been screwed over by that because the companies is like we're no longer making this switch And I'm like well, I still need it and they're like tough We're French and I'm like, okay, you know, and then I had to go and like look around I eventually did find another company that was making a compatible one, but like it was a little frustrating anyways And about that. So let's look for the active and in stock parts We also want a surface mount when we wanted a surface mount right angle, okay Why surface mount not through hole because I don't want to have a through hole soldering step You're gonna get a lot stronger switches with through hole, but I'm willing to Sacrifice that and just try to put more solder one of things I found out actually a lot of people who got matrix portals in the last eight of box their switches did break off Not a lot. It was like 10 people But it was enough in like one week that I was like wow I need to Revise the footprint for this part to give it a lot more solder small mechanically stable This is one of the things you just you send out 4,000 of something you learn There you go surface mount right angle easy. So that's really nice because it will reduce the quantity down to about 75 remaining So let's go. We'll say it did you see it's nice and fast this week They did some work on it and tell all right. So now Okay, so next step is operating force and this is a thing that a lot of people You're just like well, what's what's the deal with operating force and and how do I know what it is the answers? You don't you buy a couple switches with whatever force is available with 100 You know 150 250 and you you physically press them and you see how you feel about them In my opinion 150 is kind of like a softer but clicky switch under 100 is like soft and Over and like 250 above is like who you're like. I'm clicking. It's clicky It's very qualitative as you can tell you should just get them and Try them out. Here's something I learned today. You're wondering. What's PIP? It's paste in pad It's through hole, but it's designed so that you put like a big chunk of paste using your surface mount process and then you Can place the part with a pick-and-place machine and it goes through the reflow and so you get the best of both worlds You get like the the through hole physical strength, but the surface mount ease of manufacturing I never used this trim before but today I learned it. So Congratulations, you're gonna learn with me. I do not want it to be illuminated So get rid of that I Don't want it to be flush, but I don't know if I want rectangular button or standard. So let's go check out the difference Rectangular button standard. I don't know. I think standard or take number kind of the same Flash this one's flush and this is yeah, I don't want that That's like, you know, you have something that that um presses it. So let's go back up here and I Don't want plunger for cap. I don't want a cap. I want it to be, you know, all all in one And then I want it taping wheel don't want tubes don't want bulk Because I want this to go through the pick-and-place machine Okay, so now Let's see what we got So I will there's two things techniques you can use here, of course Well, I like to when I'm making something that's going to be manufactured. I usually like to show the prices at You know 1,000 or 5,000 the reason is is with the recent change where Tape and reel and cut tape and did you reel are not separate? Listings the pricing is a little bit tougher to compare because you see the pressing at one Quantity one you want to see the pricing at quantity five thousand because it's gonna make a big difference You're gonna it's gonna be a golf by like an order of magnitude Sometimes two orders of magnitude Okay, so there's these and you know, I actually got some of these and they were okay They're very small in my opinion but they you know and and they're softer also I felt like let me see what they They say is the Grand force so 160 But I really liked I kind of went you know and you can see again There's like a multiple supplier so Panasonic makes one and then this one also Panasonic and then like there's this one from C&K again almost the same style But and then this one was just kind of cool. This is like a weird Mutant like they took a six millimeter Right angle and then they just like bent the legs and made it a surface mount But this one was too big for me like it's kind of massive in my opinion So this is the end one I ended up with I like this one. It's an elegant Works pretty well Again these pads here. I made them like 20 30% bigger This was okay, but I did have a couple break off. So I think if I were you or if you were me Increase these pads a little bit And you can download a That's cool. You can download like a CAD model I don't know if they have a They do not have like the easy CAD. This is pretty easy to draw This footprint, but yeah, just make the the solder pads a little bit bigger And then of course it's in the data sheet as well. So this is the one I used I kind of like it I mean, it's it's it's nice and clicky. It's Easy for your fingers to feel which I like that. I like you don't have you shouldn't have to like look at the button To see if you're pressing it. So I'm using it a lot more especially where Oh, it's gonna be overhead can show so like this This design where it's going to have you know a bonnet on top of it So no there's no button like any button here. It wouldn't be accessible So with these right angles, I can still get to these buttons to press them even though there's something on top I think I like that they feel nice nice and clicky. All right. That's the great search And that's a great search
