HELP on EM key switch

[joebb]

Hi I have wired an emergency lighting circuit on a staircase and want to know the connections for the key switch, I have taken a 3 core t&e from the first light to the switch which is next to the normal switch, I have not gone to the switch with the main feed first so no neutral at switches. please HELP.

2 gang box feed to em , em out to common on 1 gang switch/ p/live to em fitting L1 to switched live on fitting

Why the T&E

 

[telectrix]

all your keyswitch does is interrupt the permanent live to the EM., so the keyswitch is N/C.
