Figure 1 Circuit converts momentary action push switch into latching power switch. To understand how the circuit operates, assume that the DC power supply, +V S , has just been applied, capacitor C1 ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

For some of us, there are few sounds more satisfying than the deep resonant “thunk” of a high quality toggle switch slamming into position. There isn’t an overabundance of viscera… ...

Push to make switch (PTM) is a momentary switch that closes the circuit only while pressed and is commonly used in doorbells and keyboards. Single pole, single throw switch (SPST) is a latching ...
