The disadvantage of this setup is that it is necessary to combine the separate parts (arc shield) into the switch housing and then properly position the base so that the base passes The opening of the cover is used to operate the bridge. Another disadvantage is that when the arc shield protects some of the parts of the seat, the large central opening in the arc shield still causes damage to the base parts that are not properly shielded. It is beneficial for rice to provide protection from the switch base by using an arc obstruction that does not have a large central opening. It is understood that this reference does not constitute an admission that the disclosure forms general knowledge in Australia or any other country, if reference is made herein to a prior art disclosure. [Disclosure] An aspect of the present invention provides The switch assembly can be at least partially overcome or provide a useful or commercial choice for the consumer. In one form, the invention resides in a base mount for electrical opening and closing having at least two components, The first component has an outer part and the first component has an arc shield, and the arc shield can be disposed inside the first component. In this form, the arc shield can be regarded as a component part of the base rather than a need A completely separate component that is separately assembled between the base and the switch housing. In other forms, the invention resides in a housing, at least one electrical contact, between an electrically open position and an electrically closed position. Moving the bridge between a open position and a closed position, moving a bridge actuator member of the bridge, and operating the bridge actuator mechanism The switch assembly has an arc shield. - In the form of the invention, preferably the base has an outer part and an inner part, the inner part comprises an arc shield. 6 than 2367 curved surface The part has a casing, and typically has a flat or optional, and = part to help the fingering of the base between the open and closed positions, the size of the base and the change of the outer material b, and the variation can be changed.

The attachment may have a sleeve or a through end of the member. Alternatively, the accessory mechanism can have a two-way swaying manner to capture, mount or otherwise operate the bridge. The accessory mechanism will have a short tubular member, the end of the bridge actuator member. ^ On: =" Two rotations are attached to the switch housing to cause rotation or play between the right and the closed position of the base. Generally, the base can be mounted with a pair of diameters in the switch housing. This arrangement is well known, but in this case, the inner part can provide a diametrically opposite rotation check as a base:: more: a shield. Therefore, the outer part of the base preferably has a concave or other type. a mechanism for opening or accommodating a rotating part of the inner part. The inner part can provide a pair of spaced apart parallel rib rib assemblies, 7 1352367 and preferably such a rib assembly can be directly attached to the rear axle frame The actuator can have an elongate member that substantially assumes a cylindrical shape and can provide a rounded front leading edge portion through which the rear portion of the elongate member can pass into a tubular member that is present on the base. A pressurized member is provided to pressurize The bridge actuator member is engaged with the bridge, and the pressing member may have an elastic crest, the spring may have a helical elastic, which may be in the vicinity of the rear portion of the bridge actuator member or The pressurizing member is provided, and preferably the pressurizing member is at least partially disposed within the tubular member on the base. The bridge will typically have a small piece of metal that is electrically conductive, the bridge will typically be mounted Rotational movement in the outer casing, and the type of such arrangement is known. [Embodiment] Referring to Figures 1 to 4, it is explained how many of the conventional bases 10 are on the outer shape. In a particular embodiment, The bottom abutment 10 can be formed by two parts, which can be best illustrated in Fig. 4, which is shown to contain a visible outer part, an outer part 11 and an inner part 12 Thousands of 1 2 can be fitted into the outer part 1 1 'which can be obtained in the 2nd and 3rd drawings, and the best part is 12, which is formed by black nailong and acts as an arc. A fox obscurity that provides a chemical to prevent deterioration of the outer part 11. The inner part 12 can provide a pair of rotating bolts 13 that are straight and 4 opposite and outwardly extending, so that the outer part u can form a large curved surface of the vehicle The recess 14 (see Figure 4) comes to the valley, the inner 4 king 1 3, the 拴丨 3 can be installed to a mile The surface of the platform 15, when the platform 8 丄妁 2367 and the second 15 pass through the recess 14 can be seen in a flattened view. The part 12 also contains a rotating 拴 13 inside the inner part 12 Extending directly to each subsequent pair of separate ribs 30. The inner portion 12 of the extension can provide the sleeve (bGSS) i6 illustrated in Figures 2 and 3, the purpose of which will be To explain.
