Angle ball switch

Technical Field

Background

The ball switch is also called a bead switch, and the principle is that the rolling of the beads in the switch is utilized to manufacture the touch with a metal terminal or change the light traveling route, so that the conducting or non-conducting effect can be generated.

When the existing angle ball switch is installed upside down (the switch is installed downwards in the vertical direction, at this time, the switch is in an off state, the switch needs to be inclined to a certain angle, and the switch is communicated when the balls fall into an on position), the triggering angle of the angle ball switch is usually 90 degrees, because the space side surface where the balls of the existing angle ball switch are located is usually a vertical surface, once the space side surface exceeds 90 degrees, the balls roll into the communicating position along the vertical surface, and the triggering angle cannot be further enlarged. It is therefore desirable to develop a new angle ball switch.

The upper part of the funnel conducting piece 3 is abutted with the inner bottom surface of the shell 1, so that the balls 2 can be prevented from rolling out of the funnel conducting piece 3 when the funnel conducting piece is inclined, and smooth movement of the balls 2 in the funnel conducting piece 3 can be ensured, and the balls cannot be blocked on a gap formed between the top surface of the funnel conducting piece 3 and the inner bottom surface of the shell 1.

In other embodiments, the top of the funnel conducting member 3 may also be spaced from the inner top surface of the housing 1. In other embodiments, the inclined surface of the middle layer may be replaced by an arc surface, and the same function may be achieved.

In other embodiments, the funnel conducting member 3 may have only an intermediate layer, that is, the inner space of the funnel conducting member 3 is in a shape of a circular table, the middle is through, and the cross section is in a circular ring shape, at this time, the first conducting rod 4 may not extend into the funnel conducting member 3, and similarly, when the ball 2 is located at the position where the inner diameter of the funnel conducting member 3 is minimum, the ball 2 is in contact connection with the contact seat 41 at the top end of the first conducting rod 4, so as to further realize electrical conduction of the ball 2, the funnel conducting member 3, the first conducting rod 4 and the second conducting rod 5.
