I am installing a fluorescent light fitting in my shed and want to install a one gang, one-way plastic light switch (with plastic back box). I have power coming into my shed from my adjoining garage's light circuit, which is 2.5mm twin & earth cable, so I have a neutral, live and earth coming into the shed. Inside the light fitting is a terminal block with N, E and L connectors but I am not sure where the switch should be wired to? Any help would be appreciated! Thanks in advance.
