What type of switch is used to monitor the rise and retraction of the BAK-14?

The BAK-14 system employs mercury-type limit switches due to their reliability in monitoring the rise and retraction of components within an electrical system. These switches are designed to respond to changes in physical position, which is essential for detecting the exact positions of moving parts. Mercury-type switches utilize a small amount of liquid mercury that adjusts its position according to the tilt of the switch, allowing for precise triggering when the desired position is reached. This sensitivity makes them particularly suited for applications where reliable and repeatable positioning is crucial, such as in the BAK-14 system.

The other types of switches mentioned, although they have their applications, do not provide the same level of reliability or sensitivity in all scenarios. Mechanical switches typically require physical contact to operate, which can introduce wear and reduce lifespan. Digital sensors, while effective for certain modern applications, may not be optimized for the specific physical movements involved. Pressure-sensitive switches work based on pressure changes and may not accurately detect the specific rising and retraction motions required for this application. Therefore, the choice of mercury-type limit switches is appropriate for the precise monitoring needs of the BAK-14 system.
