Latest Patents

One of Yogo's latest patents is a pressure switch designed with reduced contact wear. This invention features an integral housing and body case that contains a diaphragm. The diaphragm is exposed to an external signal pressure on one side and a chamber in the housing on the other side. This design allows the diaphragm to flex in response to pressure differentials. A movable rod within the housing responds to the diaphragm's flexure, carrying a movable contact that engages with fixed contacts. A first spring biases the movable contact towards the fixed contact, ensuring reliable operation.

Another significant patent is an article obtained by injection molding. This article includes a first member that houses an electrical element, such as a coil, and a second member that surrounds the first member. The second member is formed integrally with the first member. A radially inward projection of the second member abuts an annular flange of the first member, while another projection is fitted and welded to a vee on the flange. This weld serves as a waterproof seal for the electrical element, and a connecting means is provided to prevent separation due to thermal expansion.
