I'm sorry, but I am unable to physically inspect the mechanical switches. It would be best to visually inspect the switches or have a technician examine them to determine if they are broken. **

Mechanical keyboards typically use switches that have a physical mechanism underneath each keycap. Some popular types of mechanical switches include Cherry MX, Razer Green, and Logitech Romer-G switches. These switches are known for their durability, tactile feedback, and distinct clicking sound. Mechanical keyboards are favored by many gamers and typists for their responsiveness and overall typing experience. **

Old mechanical keyboards can be compared with modern mechanical switches such as Cherry MX, Gateron, and Kailh switches. These switches offer a similar tactile and audible feedback that was characteristic of old mechanical keyboards. Additionally, they provide a satisfying typing experience and durability, similar to the old mechanical switches. However, modern switches may offer additional features such as customizable actuation points and RGB lighting. **

The Sharkoon Skiller SGK3 keyboard uses mechanical switches from Kailh. These switches are known for their durability and tactile feedback, making them ideal for gaming and typing. The SGK3 is available with either Kailh Blue or Kailh Red switches, offering clicky and linear responses, respectively. These switches are designed to provide a satisfying typing experience and reliable performance for long-term use. **

An industrial engineer in mechanical engineering focuses on optimizing production processes and systems within manufacturing facilities. They work to improve efficiency, reduce waste, and increase productivity by analyzing and redesigning workflows, equipment layouts, and production schedules. Industrial engineers also collaborate with other engineers and professionals to implement new technologies and methods to enhance overall operations and quality control in a manufacturing setting. **

The choice between mechanical engineering and industrial engineering ultimately depends on an individual's interests and career goals. Mechanical engineering focuses on designing and building mechanical systems and devices, while industrial engineering focuses on optimizing complex systems and processes to improve efficiency and productivity. If someone is interested in designing and building machines and mechanical systems, mechanical engineering may be the better choice. On the other hand, if someone is more interested in improving processes and systems within a variety of industries, industrial engineering may be the better fit. It's important to consider one's strengths, interests, and career aspirations when making this decision. **

Yes, switches can typically be removed and replaced on most mechanical keyboards. However, the ease of removing and replacing switches may vary depending on the specific keyboard model and design. Some keyboards may require soldering to replace switches, while others may have hot-swappable switch sockets that allow for easy removal and replacement without soldering. It's important to check the specifications of your mechanical keyboard to determine if the switches can be easily replaced. **

Mechanical engineering focuses on the design, development, and maintenance of mechanical systems, such as engines, machines, and tools. Industrial engineering, on the other hand, is concerned with optimizing complex systems, processes, and organizations to improve efficiency and productivity. While mechanical engineers typically work on the physical components of a system, industrial engineers focus on the overall system design and management, including aspects such as supply chain management, quality control, and production planning. In summary, mechanical engineering deals with the design and maintenance of mechanical systems, while industrial engineering focuses on optimizing processes and systems for maximum efficiency. **
