Switch chain wear indicator

The proposal presents a straightforward mobile plastic glove design, where its dimensions control the range for a chain. If the chain wears out, it will miss the accommodation on the pulley, increasing the external diameter over the chain and compressing the glove to activate a switch that turns on a buzzer or light when the minimum limit is reached. The chain size determines part dimensions, while screws, springs, and switches can be standard; only the glove's manufacturing (plastic) must match with the chain and base material (e.g., aluminum, plastic, or other metal). Precision in centering the system around the pulley's center is crucial.
