latching

Hello! I have been given the opportunity to try designing a board for a 5VDC indicator/annunciator panel. There are several control panels around a building with an on/off status contact each. When closed, a 24VDC signal is sent to this annunciator panel for that particular control panel. The...

Normally working with 3 output LED, when press button in first time LED1 on LED2 and LED3 off ,then released button in first time LED1 still on LED2 and LED3 still off. When press button in secend time LED1 off LED2 on LED3 off ,then released button in secend time LED1 still off LED2 still on...

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...

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...

Hey dear everyone! I am trying to create a circuit that turns on and off. I want to do it with four Omron G2R-1-SN(S) AC 230V Relays and an industrial momentary push button (ELMARK EL2-BW07) I saw a DC circuit online that does this latching and dis-latching to turn on and off an LED but it...

Hello everyone. I have a small problem and need some help. I want to design latching circuit. And turn on my circuit when B1 pressed more than 5 second. And if it is pressed shorter than 5 second, it will not connect.

I have two 24VDC, 1.54A latching solenoids. I connected them both in parallel with power supply (80V, 80A). But when i turn ON the power supply it immediately turn off. However, when i connect a single latching solenoid with power supply it works fine. Is it necessary to use two power supplies...
