I am using a relay to control a dead simple circuit comprised of a buzzer and a 9V battery. I read the entire datasheet for the relay I purchased, and couldn't understand the schematic. The function of the circuit boils down to this:
send pulse to relay -> have buzzer ring
The pulse is sent to pins 11/12, and the buzzer rings. but the battery is getting extremely hot (I assume because the buzzer is wired in parallel with the battery...). What is the correct way to wire this? what on earth does pin 2 do?
