Nope, its exactly as i typed,

The middle pin is gnd,
If i had b, and e mixed , the switch will not work

No! Base was OK (it's the input from MPG), but collector and emitter was mixed. Emitter should be on GND and collector should go to input pin. Am I right?

Unless the chinese have marked this component incorectly. Im guessing its correct. Although it does have the characteristics of a BC817..
