[0002] Intermediate solid-state relay is an electronic component for circuit control, and its core function is to turn on or turn off load circuit through control signal (such as voltage or current). The contact type (normally open or normally closed) of traditional intermediate solid-state relay is fixed, which cannot be adjusted according to the actual needs of users. For example, some application scenarios may require normally open contacts, while others may require normally closed contacts. Due to the unadjustable contact type, users often need to purchase different models of products to meet different needs, which not only increases the procurement cost of users, but also leads to the complexity of inventory management and logistics distribution, making it difficult to adapt to such rapidly changing market demand.
