Final answer:
Solid-state switches are electronic devices that control the flow of electric current without moving parts. They offer advantages such as reliability, energy efficiency, and integration with other systems.
Step-by-step explanation:
Solid-state switches are electronic devices that can control the flow of electric current without the use of moving parts. They are made from semiconductors, such as silicon, and are used in a variety of applications, including building automation systems. These switches are finding greater use in buildings because they offer several advantages over traditional mechanical switches. For example, solid-state switches are more reliable, have a longer lifespan, and can be controlled electronically, allowing for automation and integration with other systems. They also consume less power and generate less heat, making them more energy-efficient.
