Categories	Special requirements for the main material
Signal relays	Gold-plated contacts; Use of contact wires; bifurcated contacts; Very small in size, using LCP plastic;
Power relays	PBT is mostly used in plastics; Pure copper is mostly used for static springs, and copper alloy is used for dynamic springs;
Power magnetic latching relays	The current is larger, and the reed is thicker;
Industrial relays	Similar to power relays; Most of the products with larger volume are transparent shells;
Automotive relays	The load is DC, using AgSnO contacts, and some product dynamic and static contacts are paired with different materials to reduce material transfer; The proportion of coil volume will be relatively large; Grade 180 and above enameled wire;
Hermetically sealed relays	metal shell, base; glass insulation; Plastic is not used as much as possible; Component links are mostly riveted or welded;
High voltage DC relays	use of blown magnets; Relay contacts with high currents require a sealing cavity (ceramic or plastic), a copper conductive column;
