Electromechanical switches mainly change the on/off state of a circuit through mechanical operations, such as pressing, toggling, or rotating. When mechanical parts like buttons or paddles are operated, the position of the electrical contacts is physically changed, thereby interrupting or establishing an electrical connection. Electromechanical switches usually consist of two parts: mechanical components and electronic contacts. The mechanical components receive user operation instructions and change the position of the contacts through physical movement. The electronic contacts are responsible for interrupting or establishing an electrical connection when the contact position changes. Choose the appropriate switch type according to the application scenario, such as push button switches, toggle switches, or rotary switches. Different types of switches have different operating methods and application scopes.
