Abstract: Disclosed is a battery relay for a vehicle. The battery relay has a strengthened operation structure, which includes divided upper plunger and lower plunger by dualizing an internal plunger and induces shocks of the upper plunger and the lower plunger upon initial movement of the lower plunger thereby minimizing the amount of arc generated upon contact and improving durability by shortening a switching time between a movable contact and a fixed contact.

Abstract: A structure of a battery relay is provided comprising a plunger movable upward and downward. The plunger comprises a lower portion, an upper portion, and an intermediate portion. A guide is fixed to a housing and supports the intermediate portion. A return spring is disposed on the lower portion and supports the plunger. A traveling contact is integrally formed with the plunger and movable upward and downward. A stationary contact is fixedly disposed at a lower side of the traveling contact. An exciting coil is connected to a battery switch and moves the plunger downward by being excited when the battery switch is turned on. A movable spring formed as a compression spring, is disposed on an upper portion of the traveling contact, and has one end fixed to an upper end of the plunger and another end fixed to an upper end of the guide.

Abstract: A low air pressure switch for an automobile is formed in a water resistance structure in which a connector has an integral terminal and switch body so that a moisture input passage into the interior of a switch is fully disconnected. An air outlet for an air discharge in a spring chamber of the switch body is formed inside the connector and air is discharged trough the interior of the connector and a wire core. Therefore, it is possible to effectively prevent moisture from being introduced into the interior of the switch, so that a reliability and durability of the switch are enhanced.
