From my earliest memories, shaver sockets in UK bathrooms have always been dual voltage. Years ago the voltage was selected by a slide switch rather than two seperate outlets.
Why is/was this dual voltage offered? Nowhere else in the British home is a voltage choice offered.
Were the first UK electric razors American in origin and only available in 115V - long before battery driven, 100-240V types became the norm?
Has anyone in the UK had reason to use the 115V side of these units?
