The reverse connection of a circuit to its DC power source, whether it’s a battery or power supply, can damage and even destroy the electronics. For this reason, many connectors are “keyed” to ensure correct connection. But there are many connections which are directly hard-wired using wires inserted into screw terminals, or ring or spade […]
