When you first apply the supply voltage, V S, all four transistors are off, and capacitor C 1 charges via R 1 and R 2 until its voltage, V C1, is equal to V S.The circuit is now in its off, or ...

As the pendulum shifts back toward increased use of tactile on/off switches and fewer virtual ones, new versions broaden ...

Two Momentary Switches to a Maintained Switch Dec 6, 2007 12:00 PM Most remote controls provide ample momentary closures for a command, but there are times when a maintained closure is needed. This ...

I should have been more clear now that I think about it. Yes, you can use an on/off switch with an ATX supply. It's the mobo that wants a momentary switch.

[Patman2700] has a nice scope for his paintball gun that uses a red dot instead of cross-hairs. The problem is that he kept forgetting to turn it off which ended up running the batteries down frequ… ...

Save guides, add subjects and pick up where you left off with your BBC account. Push to make switch (PTM) is a momentary switch that closes the circuit only while pressed and is commonly used in ...

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 ...
