yeh thats what i mean the switch that connects to the mobo

is it ok to connect multiple swtiches to the same plug , ie have say 2 swtiches plugged into the pw switch header on the mobo?

I would assume, that to turn the pc on 1 swtich would need to be on. And to turn it off, both would need to be off.

Well all the switch does is bridge the points for a split second, thats it.. Sure i've been using the end of a pen to start my project pc for the last month.. I don't see how having two switch's could do any harm..

pc switches dont work like that

you can switch on a pc and disconnect the switch and it will stay on

there is a certain name for the switches it uses i cant remember what the name is

Theres no logical reason why you cant have multiple power switchs? Like unklerosco said the voltage isn't constant to the mobo through the switch. All you have to make sure is that all the switchs are debouncing ones.

yeh should be fine, have to be careful with soldering it though as heat can damage the mobo if the iron is left in contact oo long or too hot

i HATE soldering hahah, il have to practice on something 1st

gline · 21-08-2006 12:38PM

are the switches u have ones that are not contantly on or off when switched, uncle???

Or Latch Switch. (Which really refers to the mechanism inside the PC that keeps it on, the switch itself is, as Sean says, a momentary contact push button switch)

thanks for the info guys, from what i can gather then it is ok to solder another switch on

il give it a shot and see how i get on

dont see why it would be bad... just leave the mobo one on and use the onr you put in the front as the power switch

Dont solder directly to the pins on the motherboard, just splice into the existing cable, and either switch will turn it on....

Speaking of switches..... Im making a CMOS clear switch for my PC

Im going to get a military style cover like this:

To avoid any accidents:p

cant do that as there is no cables soldered to the mobo it is the actual legs of the switch directly soldered to the mobo so i will have to solder my switch onto the bottom of the mobo

anyone got spare power switch from a pc case for a car-pc project
