Miniature relays are small but powerful electrical components that serve as efficient switches in various applications. Despite their compact size, these relays are capable of controlling high-power circuits through low-power control signals. As such, miniature relays have become indispensable in modern electrical and electronic systems, especially where space is limited and high-performance switching is required.
What is a Miniature Relay? A miniature relay is a type of electromagnetic switch that is smaller than traditional relays but offers the same basic functionality. It works by using an electromagnet to operate a set of contacts, which open or close depending on the relay’s control signal. When the control voltage is applied to the coil, it generates a magnetic field that attracts a movable armature. This movement causes the relay contacts to change their state, thus opening or closing the circuit they control. These relays are designed to be compact and lightweight, making them ideal for use in tight spaces where standard-sized relays would not fit. Despite their small form, miniature relays are highly effective in switching heavy-duty circuits, with their ability to handle a range of voltages and currents.
