Sweden electric regulations - light switch

[fab.elec]

Hi everyone,
Kindly I'd need to know, regarding the regulations for electrical systems in Sweden, whether light switches must be installed in a certain direction (e.g. when the light is on it must be pressed upwards) or whether there are no specifications on the regulations.

Thank you
