Hi what’s difference between 1 way and 2 Way Switch please on manual override of pir
1 Way, Switch up is PIR and Switch down is perm on
Can someone explain how would the 2 way would work and is the drawings correct the load cable for the lights is from PIR as easier than wiring from switch thanks
 
The second drawings doesn't look correct. The Switch Live for the first switch looks like its going to the supply. Switch 2 will act like switch 1 in the first pic.

Ignore above... Brain fart moment..

The first drawing is simply an override of the sensor. The live to the sensor is always there and will always work.

The second drawing has an isolator for the live so there is a way that the sensor will not work at all.

2 gang switch, not 2 way. That’s something different.
