What is not a characteristic of a broken tape switch?

A broken tape switch serves several important functions in various systems, particularly in safety and operational contexts. One key characteristic of a broken tape switch is its ability to detect when a tape is broken, which is crucial for safety mechanisms. This feature ensures that the system can react appropriately if the tape, which can be an indicator of position or function, fails.

The device also activates when the tape is broken, signaling the equipment to halt or change its operation — this safety mechanism is vital in environments where accidents might occur if doors open or close unexpectedly. Additionally, broken tape switches are often employed to detect the position of elements, such as doors, ensuring that they are correctly aligned and safe to operate.

However, the statement regarding use in hydraulic elevators is not a characteristic of broken tape switches. Broken tape switches can be found in various types of systems, but they are not specifically identified as being used in hydraulic elevators. This distinction clarifies that the primary functions of a broken tape switch revolve around detecting breaks, indicating positional safety, and promoting secure operation, rather than being tied to any one specific application like hydraulic elevators.
