For the digital time switches, this consists of memorising the days and times
of the required switching operations.

For the mechanical time switches, this is performed by positioning captive
segments or jumpers on a switching dial.

Programming by copying or blocks
Whenever identical switching operations are found at the same times, several days
in the week, this function lets you program these operations once only.
In this case a single switching operation is used. If this function is used wisely,
the number of possible switching operations can be greatly increased.
Example
Monday Tuesday Wednesday Thursday Friday

Saving on mains cut off
For digital switches equipped with this function, a lithium battery is used for saving.
The program, date and time are preserved. Switching operations are not performed.
