These are specialized clocks used for measuring time intervals. They are designed to count for specific periods and generate delays. The timers
can be grouped into two: timers that count starting from zero upwards (these are commonly referred to as stopwatch), and timers that count from specific time intervals (simply referred to as timers). The timers can be mechanical, electromechanical, or electronic in design. The mechanical timer designs utilize clockwork for measuring time. They are set through turning dials to the preferred intervals. Well, they function like an alarm clock. In the case of electromechanical timers, they use bi-metallic electromechanical timers with thermal mechanisms featuring protrusions designed of metal strips with differing expansion rates. When an electric current passes via the strips, they expand towards an electrical switch contact. The last model, that is very common in industrial and commercial facilities, is the electronic type of timers. These are special clocks with additional electronics to help them achieve higher levels of precision compared to the mechanical models. Most of them are implemented as single-chip computer systems and are relatively cheap.
