Hi, what we're looking at today is a LG single-pole double-throw relay. This one was taken out from microwave and it is model number Sierra Zune Mike- Victor 16-Foxstra Alpha-61. This is an X-100MAh 125V DC. 300MAh 250V DC. I don't actually know what the rest of the numbers mean without looking them up, but anyway, this is a single-pole double-throw. Basically, this one is open. I've opened it up, which is very easy to do. Well, on some microswitches, most microswitches, they're heat-staked shut, which means there's plastic rivets which are welded either with heat or ultrasonic welding to seal them shut, but this one was actually open, openable. This lid here, which has actually got the second diagram on it, schematic is actually on there. When the camera actually focuses up, we can see it. Okay, so you can see here that we have the normally closed at the top, normally open at the bottom, which pertains to here, normally closed, here, normally open, and the common, which is actually the commutator, is this one here. This connection here. So basically, when the microswitches triggered, like this, you can see here the contacts on the trigger mechanism, the actuator. This thing here is called the actuator, to actuate the switch. When you push that in, it pushes a little lever, which is spring loaded, and it clicks onto the bottom. I hope you can see that, okay. So, yeah, so this one here is the commutator. This is normally closed, as you can see, the contacts are closed, short circuit, and this one here is normally open. So when you push that down, the electrical path is through here, through here, and out through here. When you release it, the electrical path is through here, up here, through there, and at the top. So there you go. Yeah, nice little microswitches, that would day microwave. That I found this. Excuse me. That I found this, they're nice. So that little spring there, that's the bow spring, which is here. That bow spring basically keeps this lever and attention pushing it upwards. So it's resisting me pushing it downwards with the actuator. So I'm going to push it down. It flips over and closes the circuit at the bottom. Let go, back up the top. I say this one is made by LG, and that's the lid. Show you inside the lid. It's a push fit one. So let's really do it. Put that on there. You can see, and squeeze it back shut again. I actually got a full these at this my right hand brake please. It's a good little find. There's a single pole single throw, which has got a normally closed on it. Sorry, normally open. This one is pushed to make. Basically, a single pole means you can only put one connection through it either positive, negative, whatever. Single gang. Yeah, I'm sure you know, SPST and SDPDT etc. for double, whole double throw, single pole, double throw. Another single pole, single throw here. Get again. This one is normally open. Push to close. You see this, let me show you again, these markings here relate to the speed here, the speed terminal here. This one has a normally closed missing. It's a configuration doesn't require that terminal. And here, the single pole, double throw. So, in the rest state, the comment with the actuator up, the circuit goes from here, through here, up here, and out through there. And when the actuator is pushed in, we go up here, up here, and out through there. And out. There you go. Micro switches, made by LG, from a microwave. See you soon. Bye.
