If the timing mechanism of a time-delay relay is broken, which function is most likely affected?

• A. The relay will switch contacts immediately
• B. The relay will fail to time a delayed state
• C. The relay will not energize coil
• D. The relay will oscillate rapidly

Answer: (B)

The timing function is what creates the controlled delay before the relay’s contacts change state. When the timing mechanism is working, after a trigger or coil energization the contacts don’t switch immediately; they wait for the programmed interval. If that timing mechanism is broken, the relay loses its ability to produce that delayed transition, so it won’t reach the intended delayed state.

The coil can still energize, and the timer issue doesn’t inherently cause rapid oscillation. Immediate switching would require the timer to be bypassed or stuck in a mode that bypasses delay, which is not the typical symptom of a broken timer. So the most likely effect is that the relay fails to time a delayed state.
