Problems solved by technology
However, in the toggle switch described in Patent Document 1, if the space between the side walls of the housing is narrowed, the gap between the side walls and the movable contact is insufficient, making it difficult to maintain insulation durability. thinner
That is, since the side wall portion and the movable contact portion are close together, the metal powder generated due to the approach or separation of the movable contact portion and the fixed contact portion will splash on the side wall portion, so that when the power is OFF (the switch is in the OFF state) may form an apparent conduction path when the

Embodiment Construction
[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, a case where the present invention is applied to a bipolar toggle switch corresponding to two power supply circuits will be described below. However, the application object of the seesaw switch concerning this embodiment is not limited to this, It can change suitably.
[0028] refer to figure 1 as well as figure 2 Describe the overall structure of the toggle switch. figure 1 It is a perspective view of the toggle switch related to the embodiment of the present invention. figure 2 It is an exploded perspective view of the toggle switch according to the embodiment of the present invention.
[0029] Such as figure 1 as well as figure 2 As shown, the structure of the toggle switch 1 involved in this embodiment is that the operation part 3 is swingably installed on the casing 2 with an opening on the upper surface, and the ON and OFF of the powe...

Provided is an interactive change-over switch capable of being thin when the switch is maintained in the OFF state with the insulation durability. The interactive change-over switch (1) comprises a housing (2) configured with a fixed contact part (42); an operation part (3) swingly configured in the housing (2), which controls a movable contact part (63) to be in contact with the fixed contact part (42) or separated from the fixed contact part (42); a pair of side wall parts (11) arranged opposite to each other respectively in the shorter edge direction of the housing and arranged on the housing (2); a separating wall part (15) dividing the housing into two parts; an extension part (34) arranged on the operation part (3) on two sides of the housing along the inner sides of the side wall parts (11) and the separating wall part (15). When the fixed contact part (42) is separated from the movable contact part (63), the extension part (34) is arranged between the side wall parts (11) and the movable contact part, and between the separating wall part (15) and the movable contact part.
Description
technical field [0001] The invention relates to a toggle switch, in particular to a thin toggle switch used as a power switch for various electronic equipment such as liquid crystal televisions or plasma televisions. Background technique [0002] Conventionally, as a toggle switch used as a power switch of various electronic devices, a switch that switches the power supply ON and OFF by swinging an operation portion is known (for example, refer to Patent Document 1). In this toggle switch, an operation unit for operating a movable contact unit is arranged so as to be swingable in a casing with an open upper surface. The movable contact part can contact or separate the fixed contact part provided on the bottom wall part of the housing. Then, by swinging the operating portion, the movable contact portion and the fixed contact portion are brought into contact with or separated from each other, thereby switching ON / OFF of the power supply. [0003] Furthermore, in the above-me...
