Question 336Electricity & Electronics - QMED

The correct answer is D) maintaining type push button with a mechanical interlock. The symbol shown in figure "6" of the illustration EL-0026 represents a maintaining type push button with a mechanical interlock. This type of switch is commonly used in electrical systems to control a circuit and ensure that a specific sequence of operations is followed, often for safety reasons. The other answer choices are incorrect because: A) does not represent a mechanical interlock, B) represents a normally closed contact held open by an interlock, and C) represents a limit switch with normally open contacts, none of which match the symbol shown in the illustration.
