What is a primary disadvantage of motor driven timers?

The primary disadvantage of motor-driven timers being considered as expensive is tied to the mechanics involved in their design and manufacturing. Motor-driven timers utilize moving parts and electrical components that can be costly to produce and assemble compared to simpler electronic timers. These timers often require a more robust design to accommodate the motor functions, leading to increased material and labor costs.

In practical applications, the expense can lead to a preference for less complicated timing mechanisms, especially in situations where basic timing functions are sufficient. Additionally, the higher cost can deter businesses from opting for these timers when budget constraints are a major consideration. The complexity associated with motor-driven timers does not offer significant advantages over other types in some instances, making the investment less appealing from an economic standpoint.

This understanding helps in appreciating why the functionality, noise levels, and programming ease might not be the primary concerns when weighing the overall value and practicality of motor-driven timers in specific applications.
