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.
