A clock face with an arrow, or the letter h with a number.
Also known as: Timer symbol, Clock with an arrow on an appliance, Delay timer
A timer mark deferring the start of a cycle. It matters more than it looks: on a time-of-use electricity tariff the same wash costs materially less overnight, and this is the control that moves it there.
A clock face, often with a curved arrow, marking the control that defers the start of a programme by a set number of hours.
What a given programme actually does is in the appliance's own instructions. The symbol names the function; the manufacturer decides how it behaves.
Contexts: Electrical equipment
Sets a delay before starting on most appliances and a finishing time on some, which is a real difference: the same number means the cycle starts in three hours or ends in three hours depending on the machine.
Start-in and finish-by are both common and are not distinguished by the symbol.
A circle with two short hands radiating from its centre, sometimes with a curved arrow round the outside, beside a numeral and the letter h.
