導通不良となる場合があった。Conventional configuration and problems Regarding the lid switch of a washing machine that performs electronic operation control, the contact part is made of a flexible material such as a thin phosphor bronze plate or a stainless steel plate, as shown in Figure 6. A movable contact piece 1 and a fixed contact piece 2 are formed using a phosphor bronze plate, and the surface thereof is plated with scissors to form a contact, and a stainless steel plate is used as a contact point.
Contacts were made from raw material or by gold plating on the surface, but when performing electronic control, control is often performed using minute voltages and minute currents, and with conventional contacts and contacts, both contacts are in the ON state. The contact is a line contact or a point contact, and if fine organic dirt such as fine detergent powder adheres to the contact, poor conductivity may occur and the operation may stop. In addition, vibrations during dehydration operation may cause contact parts to wear out and corrode, resulting in poor continuity.

視図である。In electronically controlled lid switches, as described above, it is necessary to provide a large difference between opening and closing of the lid and opening and closing of contacts due to the operation of the unbalanced lever. This means that when the user opens and closes the lid quickly, for example, it is necessary to lengthen the contact 0FF-ON time when the lid is opened and closed so that the user does not mistakenly believe that an imbalance has been detected. In the present invention, the shape of the movable body 30 is changed when the lid is opened/closed and when the unbalanced lever is operated.
This is effectively achieved by supporting the movable body using the zero shape and an unbalanced lever. FIG. 4 is an exploded view of the lid switch section.
