____ provide a delayed action changing operating states of the contacts associated with its control coil.

A) Indicator lamps
B) Timing relays
C) Ladder rungs
D) Thermal overload

Timing relays provide a set delay before changing the operating states of contacts associated with its control coil. Indicator lamps simply indicate the status of a circuit and do not have the ability to control contacts. Ladder rungs are part of a programming language used in PLC programming and do not directly control contacts. Thermal overload devices are used to protect equipment from overheating and do not have control over contacts.
