you need a 3 position switch, sensor and floodlight
neutral goes to floodlight
at the switch
its like 2 circuits
position 1 live goes to pir then from pir to lamp
position 2 off
position 3 live goes to lamp
position 1 operates pir
position 2 off
position 3 lamp on constant
alternative is to buy a sencorlight with that function. they are like gold dust.
