Tungsten Points in Automotive Relay

Tungsten points play an important part in automotive relay. Magnetic system, contact system and restoring mechanism can be regarded as constituting an automotive relay. Tungsten points are applied in contact system; restoring mechanism is consisting of tension spring; magnetic system is composed of the core, the coil and the armature.

Due to relay is an automatic control device, the output will change by leaps and bounds when the input reaches up to a certain value.

Harsh conditions of tungsten points in automotive relay:
Bearing high load power;
Withstanding instable voltage;
Owning nice anti-seismic performance and better impact resistance;
Possessing corrosion resistance, tungsten points can resist the erosion of oil, salt, water, sand, dust, and others;
Temperature range: 40 ℃ ~ 125 ℃ around, if it is in other locations, its temperature range is between -40 ℃and 85 ℃.
