Review on 💡 Convenient 2 Pin PC Power Cable: Warmstor 3 Pack On/Off Push Button Switch for ATX Computer by Eric Young

Good price for 3 momentary power buttons for computer. I use mine to clear the CMOS jumper buttons. As a true replacement for a power button, I don't know how anyone would want to use them specifically for long periods of time (they're generally awkward to press, but that's not why I bought them). The edges are rough and the hard repeated presses make it unwise to use the case's power button for long periods of time, so you might want to look for an alternative.
