I have an ac relay jqc-3fc t73 dc5v that I am trying to use with a atmega and drive with 5v. Is the wiring as shown in the picture a good idea?

Considering that ac and DC need to be very close together on the pins? The brass thing will be carrying v ac. The jumpers carry DC. The relay will drive the pump as shown in the picture. The wooden box will be used to contain the relay and ac lines.

That will have much safer connections on the AC side. Active Oldest Votes. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.
