Abstract
A pressure switch is disclosed. The pressure switch includes a housing and a pressure-receiving chamber that communicates with a duct to which an operating pressure is supplied. The pressure switch also includes a diaphragm assembly with a diaphragm that is displaced in response to a pressure inside the pressure-receiving chamber. The pressure switch also includes a movable contact that comes into contact with a fixed contact accommodated in a center portion of an inside of the housing when the pressure inside the pressure-receiving chamber is above a certain value. One of the movable contact and the fixed contact has radially diverging contact faces that are arranged such that contact between the fixed contact and the moveable contact can be established with at least two of the radially diverging contact faces at the same time.
