A power window switch configured to electrically control opening and closing of a window by pushing and pulling the switch button together with the configuration of the invention according to claim 1, 2, or 3 .

[0012]

According to the present invention, the switch button is
Since the upper surface (front surface) of the switch button is formed such that one side has a longer distance to the fulcrum and the other side has a shorter distance to the fulcrum, when a pressing force is applied to the switch button, The switch button is easily tilted so that one side (the side with a longer distance from the fulcrum) is lowered.

The switch button forms an operation section for performing push and pull operations with one's finger on the one side (the side with the longest distance from the fulcrum), and the other side (the distance from the fulcrum). (Short side) is formed with a gentle round on the upper surface of the switch button so that it is difficult to operate with a human finger, so that the one side is more likely to fall down (unintended by humans) One side never goes up).

[0014] Thus, for mechanical operation which may risk to be operated with care occurs, the switch button hand side (distance is long side from the fulcrum) is the direction rises above the If the switch button is tilted, even if a person accidentally touches the switch button and the pressing force is applied to the switch button (falls down), the switch button remains on one side (a long distance from the fulcrum). Side) is tilted down so that potentially dangerous mechanical operations are not performed, no danger occurs and safety against erroneous operation is increased.

In particular, in a power window switch, the switch operation in a direction in which one side of the switch button (the side longer from the fulcrum) is lowered is used to open the window, and the above-mentioned one side (the fulcrum is used). If you set the switch operation to the direction where the distance from the (longer distance to the longer side) rises in accordance with the closing of the window, the window will open if you accidentally touch the switch button or get weight. Even if there is, the window does not close, so that it is possible to reliably prevent a dangerous situation such as pinching of the body or neck between the window frame and the glass, thereby increasing the safety against erroneous operation.

Furthermore, if the other side of the fulcrum of the switch button is formed with a gentle round on the upper surface of the switch button so that it is difficult to operate with a human finger, the switch button from the other side can be formed. Erroneous operation of the switch device can be completely prevented, and safety against erroneous operation of the switch device can be further improved.
