10. Pull-string light switches, Great Britain
Bathrooms in old British houses still have pull-string light switches. They are there for safety reasons because humidity and electricity are a dangerous mixture. Standard light switches were not used in bathrooms because residents were afraid that they might be in danger of electric shock. This switch could’ve been placed just outside the bathrooms, but British people decided to solve it this way and now a pull-string light switch is an outstanding feature of English houses.
