PURPOSE: An electric actuator and a relay thereof are provided to prevent the contact between metals when a moving core is driven by forming a buffering part using a material having a lower hardness. CONSTITUTION: A fixed contact point(120) is arranged in a base(110). A moving contact point(130) is detachably arranged to the fixed contact point. An electric actuator(150) drives the moving contact point in order to separate the moving contact point from the fixed contact point. The electric actuator comprises a coil(160), a fixed core(170) which is arranged inside the coil, a moving core which is arranged to be separated from the fixed core, and a buffering part(210). The buffering part, which has lower hardness than the moving core, is arranged in the vicinity of the moving core. |
