Ah yes i see i can plug relays into the computer. That's good.
It can give a pulse. That's a good start
Any idea how to switch off power with such pulse? Probably need another device that i plug into the relay then? |
A relay is an open-close device. It is either open or closed. You generally get two connections that bridge the relay contacts. Only question is, how many amps do you need to switch? The ones I saw were good for 10a, which is probably way more than enough. You just run the hot leg of A/C power to one side of the relay, the other side of the relay goes to the hot wire connection in the switch, and you will be set... |
