An electrical system may include a mounting surface, a component configured for connection with the mounting surface and configured to move relative to the mounting surface, and/or an orientation sensor configured to determining an orientation of the component relative to the mounting surface. The orientation sensor may include a first sensor (e.g., a magnetometer, an accelerometer, a gyroscope, etc.) connected, at least indirectly, to the mounting surface, and a second sensor (e.g., a magnetometer, an accelerometer, a gyroscope, etc.) connected to move with the component. The orientation sensor may include an electronic controller. The electronic controller may be configured to compare first information from the first sensor to second information from the second sensor to determine the orientation of the component relative to the mounting surface.
