Summary:PURPOSE: A relay is provided to stably contact a movable contact point and a fixed contact point by removing an air gap due to the unstable contact of the movable contact point and the fixed contact point. CONSTITUTION: A solenoid(10) includes a spool, a coil wound around the spool, and a pair of power connection terminals formed on one side of the spool. A chamber(20) includes a cylinder inserted into the center of the spool and a pair of fixed terminals with a fixed contact point. An insulation gas is filled in a chamber. An insulation unit(70) insulates the chamber and the fixed terminal. A shaft moves to the upper side of the inside of the chamber when a solenoid operates. An operation unit is comprised of a pair of movable contact points which is selectively contacted with the movable terminal and the fixed contact point vertically coupled with the upper side of the shaft. A recovery spring is combined with the lower sides of the cylinder and the shaft. A sliding guide guides the movable unit which moves by the solenoid and the recovery spring.
