WebApr 16, 2024 · The basis of any reed relay is the reed switch itself - this is the core element in an reed relay. The reed switch consists of two reed contacts whatever been made from nickel-iron and then plated with materials to making the maximum working life spanning. The reed switch contacts overlap so when they close they make contact with each other.
Reed switches have been manufactured since the 1930s. Compared with armature-based relays, reed relays can switch much faster, as the moving parts are small and lightweight, although switch bounce is still present. Also, they require less operating power and have lower contact capacitance. See more A reed relay is a type of relay that uses an electromagnet to control one or more reed switches. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move … See more A few million reed relays were used from the 1930s to the 1960s for memory functions in Bell System electromechanical telephone exchanges. … See more Reed arrays passed out of use in the mid-1990s, being unnecessary in digital telephone systems such as DMS-100 and 5ESS switch.
