Thanks and can see why this might happen. As I didn’t take it out when bleeding before (and yes then I didn’t follow instructions to the letter it seems) would it be obvious if switch trigger is damaged? I’ve taken it out, just looks like black plastic pin - hard to see if it maybe had more on end before. Also, looking into the hole where it fits, can see piston there with line on - I’m assuming that’s the central mark? I’m loath to open everything again just to check centralised tbh.
