The utility model relates to power equipment field and especially relates to an air switch. An elastic static contact air switch contact mechanism comprises an insulating arc extinguishing chamber housing, a static contact, a moving contact, a non-linear resistor chamber, and a non-linear resistor. The two ends of the non-linear resistor are connected with the wiring end of the static contact and the wiring end of the moving contact, respectively. A protruding clamping ring is disposed round the contact end of the moving contact. The contact end of the static contact is equipped with a plurality of elastic damping claws in cooperation with the clamping ring. The contact end of the static contact is disposed in the insulating arc extinguishing chamber housing. The wiring end of the static contact is extended out of the insulating arc extinguishing chamber housing to be connected with a leading-out end. A reset spring is sleeved on the wiring end of the static contact. The elastic static contact air switch contact mechanism increases the speed of relative motion between the static contact and the moving contact when a brake is separated and has characteristics of a strong arc extinguishing capability, good voltage withstand performance, a long service life, and no outwardly-sprayed arc. The elastic static contact air switch contact mechanism is suitable for a high-voltage circuit and guarantees the safe operation of electrical devices.
