switch

Hi, I am looking for a transistor that I can use as a switch at a minimum frequency of 10 MHz. So far, I haven’t been able to find a suitable component, and I would really appreciate your assistance or recommendations. My circuit is intended to look like this: Thank you very much for your help.

I have a circuit that is connected to a solar panel that goes to sleep during the night. At that point it does not allow current to flow even when the sun comes up. The only way to “wake it up “ is to disconnect and reconnect the solar panel. I am looking for a self powered (9 volt or AAA...

Hi! I have an paper due tomorrow and a really need spice model for MAX4053 and MAX4052. It would really help if someone can give me sub or lib file for those. Thank you!

I have been recently working on a board which just breaks out a few switches and LEDs for easy soldering to a Raspberry Pi. There isn't much of a circuit, but I would like guidance if I chose suitable resistors, etc. I have two LEDs - APT2012LZGCK (2mA @ 2.65Vf - with a 330Ω res.) and an...

I made my DAB Converter in LTspice and it seems to work whenever the NMOS are replaced with switches but I have no idea why if I just replace them the switches with MOSFETs it doesn't work anymore. As shown in the screenshot if I replace the NMOS for the S1 PWM as well as the S4 PWM, my DAB...

Hi all, Not sure this is the right place but Im looking for some expertise/help in understanding design of a simple circuit. Im looking to make something that would make a noise after being triggered by either impact or a magnet. Looking for this to be very very small also. Smaller than a...

Hi all, hi Ya’akov. My previous (relay mute) project is running nicely for 4 months now. Time for a new BMW project. This time, I want to add extra LED lights in the trunk. I thought there could be an easier way, instead of tapping into the trunk lighting switch and pulling wires into the...

I have this non-latching metal power switch with an LED inside, to light up the "power symbol" on the switch. I am currently looking after a circuit that can make this LED gently fade-in whenever power is connected to the circuit. The switch uses a "standard" (or "normal") LED. The...

Hi everyone and thank you for your time, I am having a problem where on my car my position lights work only during night time if left on automatic and in my country by law you need to have at least position on in daytime so I wanted to make them work when the engine is running during the day but...

Dear All, I want to install a so-called 'kill switch' in my electric guitar and I need a specific switch that DOES allow electricity to pass through in 'normal' mode, but NOT when you press it. The switch should also spring back automatically when you press it. I found the following on bol.com...

Hi all, I am a mechanical engineer and very limited in my electronics knowledge so please forgive me if this is a fairly simple question for you wizards. I am working on a hobby project where I'm fitting an Intel NUC into a GameCube case. I want to reuse the GC's original power switch, which...

What is the role and purpose of the 470uf capacitor? Is it simply disconnected because it's connected in parallel with 330uF? And 5 pin out is 15V pulse or low pulse? What is the expected transformer ratio?

Hello everybody.I have to implement the in house circuit cc-ih circuit which is an energy harvester circuit using simscape electrical. The description of the circuit can be found on page 7 of the pdf at Finite element-based assessment of energy harvesting in composite beams with piezoelectric...

I have a mechanical system I'm building and I want to use snap switches to control the order of operations. The order will be something like this. 1. Run 1 revolution of the electric motor, then stop motor. 2. Activate solenoid. 3. Activate second electric motor for 1 revolution. 4. Begin...

I am currently working on a project (Tesla Coil) and I built a very simple controller which connects to the neon sign transformer (NST). First there is a main switch which connects to the 120V mains and then a second "activate" switch which provides power to the NST. This is the current design...

Hi all, I'm looking for some help with a light switch from the rear interior lights of a Vauxhall Insignia. I've scoured the internet with the parts numbers and manufacturer assembly numbers etc and came back with no results. All I know is that this is an on/off push button switch made by...

Hi, I have an electric hoist trupper brand, this comes with a control and a switch that disables the ascent after a certain point, I want to add another to disable the descent. I tried putting the switch between B and 10 but it disabled the up and made it go down if I pressed up or down. I...

Hey Guys, I have a weird question about SmartHome door Sensors. I purchased one just to look at it and I am confused. There is the main control board and shell and then the magnet and shell. With home alarms reed switchs are used the the magnet opens or closes the switch. I was expecting the...

Hi, The CD4053B has only 3 identical bilateral analog spdt switches on it. Does anyone know of any chip that has more so I don't have to buy too many of these? Thanks.

Hello all, I’m helping my daughter with a design project and part of it needs a simple led control circuit. Using a single push button and 4 leds, I need an ic circuit that would light led 1 with th e first button push, led 1 &2 with the second, led 1,2,&3 with the third button push, leds...
