Description
Power On/Off Button
Look ...
I decided to make DIY Laboratory Power Supply .
I found all component that i need , i bought a DIY plastic box as case for it , i selected a Voltmeter, DC-DC Adjustable Buck and Boost modules and put it all in the case .
I like all i did , but not the power button . It was a small latching Metal Push Button . Then i decided that i need a button like we see in PCs or in other gadgets . I want to make a button without latching like you press to power on and press again to power off .
Here is the circuit for my Power Button realization .
You can also find all modules pictures chosen by me attached .
