Problems solved by technology

[0007] However, in the structure of the above-mentioned conventional tilt detector, the above-mentioned first fixed contacts 12a, 12b and the second fixed contacts 13a, 13b are provided on the above-mentioned insulating substrate 11, and errors easily occur between the contacts. The problem is: the contact is unstable and the detection accuracy is not high
And, structurally, only two directions of inclination can be detected

Abstract

A spherical movable contact is housed in housing portions of a first case and a second case so as to be able to roll, and is to come into or go out of contact with a first fixed contact and a second fixed contact. The first case and the second case are fixed to each other so as to form an integral body in such a manner that the first fixed contact and the second fixed contact are opposed to each other. At least one of the first fixed contact and the second fixed contact is divided. The movable contact is disposed so as to roll while bridging the first fixed contact and the second fixed contact. Contact portions where the movable contact is to contact the first fixed contact and the second fixed contact assume arc shapes, respectively.

Description

technical field [0001] The present invention relates to the structure of a tilt detector used in products having a direction detection function used in various portable electronic devices, home game machines, toys, and the like. Background technique [0002] The structure of the existing tilt detector is shown in Figure 8 ~ Figure 10 . Figure 8 is the exploded oblique view of the tilt detector, Figure 9 It is a longitudinal sectional view viewed from the side, Figure 10 It is an explanatory diagram showing the operating state of the spherical movable contact. [0003] As shown in the figure, the components of the existing tilt detector include: an insulating substrate 11, which is made of insulating material; first fixed contacts 12a, 12b, which are made of conductive metal plates, and are arranged side by side on the above-mentioned On the insulating substrate 11; the second fixed contacts 13a, 13b, which are adjacent to the first fixed contacts 12a, 12b, arranged si...
