Answer:
Both technicians are correct! A push-button switch is a type of switch that is activated by pressing a button. It can be either momentary or maintained, which means it stays in the "on" or "off" position when the button is released.
Step-by-step explanation:
A pressure switch is a special type of push-button switch that operates based on pressure, as Technician B stated. The switch stays in one position until a certain pressure is applied to the button, at which point it switches to the opposite position. This makes it ideal for applications where a switch needs to be activated by a physical force, such as when a certain pressure is reached in a fluid system.
So, both technicians have correctly described different aspects of push-button switches.
