Some relays have a built-in diode to protect the switch turning the coil on and off. If it does not, then install
a diode across your switch contacts to protect it from the big spark when you turn the coil off.
and remember to wire it with the anode to the negative post and the cathode to the positive or it will forward conduct when you go to pick up the coil.
