Mechanical counters are devices used to count objects or events through a mechanical mechanism. They typically consist of gears and levers that move in response to a physical action, such as pressing a button or rotating a dial. Each action increments the count displayed on the counter, making it useful in various applications, from industrial settings to simple tallying tasks. These counters can be found in many forms, including hand-held counters and odometers in vehicles. They are often preferred for their simplicity and reliability, as they do not require batteries or electronic components, making them easy to use in various environments.
