Is there such a thing as a switch that can be actuated automatically?

I'm interested in a toggle switch that can be toggled without user input. That is, the physical state can be toggled electrically. It would need to incorporate some sort of motor or magnetic actuator. My google-fu is weak in this area, and I haven't…

Smooth switching between 12 V batteries, with a toggle switch

I have a number of instruments (12 volts, drawing a few hundred milliamperes) that occasionally need to be switched between one of two 12 volt lead acid batteries. The toggle switch is break-before-make, so there's a fraction of a second…

switch between battery and usb power no microcontroller circuit

Following an earlier question about how to switch between battery and USB power, I would love to implement the TC2014 LDO as suggested by Russell McMahon. That way I could switch between 4AA batteries (1.2V*4 or 1.5V*4) and USB power. The battery…

What is the correct term and schematic symbol for a bar "connecting" multiple toggles together?

This has driven me mad, I've searched for this on google and am now going to the world to find out what the part is called. I've tried things like "Gang bar", "shared cover", did a google image search of the two images I have, and anything else I…

Switching on an SSR on positive voltage and turn it off on negative voltage

I am currently trying to "hack" my way through a door lock, whose PCB cannot be changed. The task is to replace the motor for turning the cylinder with a Solid State Relay. However, the only contacts available are the ones of the motor itself. Some…

Problem with DIY fuzz stompbox FX pedal

first post here I was wanting some help with a fuzz pedal kit I recently bought on ebay. I'm relatively new to electronics and I'm no genius in this area, but I've been really frustrated for the past few days. I built this circuitboard exactly as I…

Determining initial state of the circuit that uses 74HC00

I've built the following circuit that makes a push-button work like a toggle switch: It works exactly as expected. Pressing the button once turns the LED on. Pressing the button once again turns it off. However, there is one thing I don't…

How do you design a switch input to a MCU for ultra low power consumption?

I'm trying to build a low power door monitoring switch. I'm using an MSP430FR2311 with the below circuit. The switch is a SPST reed switch and there is an internal pull-down resistor on pin P1.0 of the MCU. When the switch is open power…

What do you call a pair of SPDT switches controlled by one toggle?

I need a toggle switch which allows me to switch the poles of two separate single-pole-double-throw switches together. It would work like the diagram below. Note that the dotted line represents a physical connection not an electrical one. I need…

Is there any such thing as a tristable, quadristable, etc. multivibrator?

The title says it all. Is there a discrete circuit that can produce 4 different outputs based on a single tactile switch click? I'd like to do this with either a discrete design or a 74373 since these are all the parts I have on hand. I'm living in…

Can't make toggle with TC4013BP

Beginner to circuit building here. I tried to build the following toggle switch using one side of a TC4013BP [EDIT: I'm using a 9 V power supply, why did I write 12V? Sorry!]: (I know, white wires with a white breadboard, great choice....) This is…

How to toggle relay with single push-button

I believe there is a simple circuit, that uses a single non latching push button (1 or more pole possible?) to toggle 12V relay. 1 press - ON state, another press - OFF state and so on. I can't find it anywhere, I searched over the internet as much…

Push button for different actions in every press?

I'm trying to learn some electronics and I have something in mind that I don't know if it is possible to achieve. I've worked before with micro-controllers (Arduino, etc) and I know I would be able to do this with code, but I would like to know if…
