Its actually pretty common, the behavior comes from that circuitry that protects the relay, they usually use some sort of opto-isolator. And this circuit expects a HIGH signal to be close to VCC, so by lowering VCC to 3.3V, then an input of 3.3V is read as HIGH, whereas if VCC is 5V then 3.3V doesnt always read as HIGH. david nish derby county
