I'm trying to test the 5V version of the relay listed at the web address below.
I have tried applying 6V directly from a battery to pin 6 with ground connected to pin 7, also tried the same for pin 1 and 12, but I don't hear any switching. Checking the resistance between pins 3 and 5 (and 10 and 8) shows an open connection (many megaOhms on my multimeter).
Which coil should close the relay? 6/7 or 1/12? I can't tell from the diagram. And why isn't it latching? I'm certain this question demonstrates a fundamental lack of understanding about latching relays. Please help a novice. Thanks!!
