The tape-type switch placed inside the window frame works as a detector to detect if a part of the human body or an object is caught between the window glass and the frame when the window is closed. , is installed to immediately stop the window glass from rising to ensure the safety of drivers and others. For this reason, tape-type switches are thin, elongated, flexible, and can be used in a folded state, and are equipped with at least one pair of electrodes, so that when pressed at any one point on the long switch body, both The electrodes must be in contact to operate.

Electrodes 3 and 2 are placed inside tapes 1 and 2 made of flexible insulating materials such as polyethylene and polyester, respectively.

つた。 However, since the conventional spacer 6 is made of an insulating material such as polyester or silicone rubber, the entire tape-type switch has the shape of a capacitor. For this reason, the tapes 1 and 2 were charged with static electricity, creating a large potential difference between the electrodes 3 and 4, which could destroy the integrated circuit element connected to the electrodes 3 and 4.

The present invention is characterized in that the spacer of this type of tape-type switch is made of a conductive material with high electrical resistivity, and the electric charge of the tape charged by static electricity gradually passes through the spacer when the switch is not in operation. It is designed so that a large potential difference due to static electricity does not occur between the electrodes by allowing the electrode to move between the electrodes.

The tape type switch according to the present invention differs from the conventional one in the material of the spacer 6, as mentioned above. That is, in the present invention, the spacer 6 is formed of a conductive material with high resistivity, for example, a conductive polymer material such as silicone rubber or plastic mixed with a small amount of carbon or metal powder. The resistivity of this spacer 6 is 10 4 ~

In the tape-type switch according to the present invention, the spacer has a slight electrical conductivity, so that the electric charge on the tape can be transferred through the spacer even when the switch is not in operation. Therefore, even if the tape is charged with static electricity, it disappears by itself and no large potential difference is generated between the electrodes, so it is possible to prevent electrostatic damage to the integrated circuit components used when connected to the tape type switch.
