Which contact symbol correctly represents a limit switch?

The correct contact symbol that represents a limit switch is often depicted as a normally open (NO) or normally closed (NC) contact, usually distinguished by its specific graphical representation. Limit switches are used in various applications to detect the presence or position of an object, ensuring that machinery operates within safe parameters or specific conditions.

In this context, the symbol must effectively convey the function of the limit switch, which typically involves the operation of its contacts based on the physical position of an object. If "A" represents the correct symbol, it is likely designed to clearly showcase this functionality, such as having appropriate labeling or visual cues that indicate its association with limit switches.

Symbols used for limit switches often feature distinctive characteristics such as the incorporation of arrows or specific terminals indicating actuation by mechanical movement or limit detection. This ensures that those interpreting the symbol can easily recognize it as a device that signals operational boundaries or conditions.

In summary, the representation of "A" encapsulates the essential attributes of a limit switch, highlighting its role in controlling or monitoring equipment based on positional inputs.
