_________________ are devices activated by contact with an object that changes the state of its contacts when the object exerts a certain amount of force.
A) Limit switches
B) Inductive proximity switches
C) Photoelectric proximity switches
D) Hall effect sensors

Question

Quizplus · Accepted Answer

Limit switches are devices that are activated by the physical contact or presence of an object. When the object exerts a certain amount of force on the switch, it changes the state of its electrical contacts, either making or breaking an electrical connection. This is in contrast to inductive and photoelectric proximity switches, and Hall effect sensors, which do not require physical contact to operate.
