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 .
