6. The novel compact bi-directional rocker button switch for automotive interiors of claim 2, characterized in that: the shell (1) comprises an upper shell (11) and a lower shell (12), the bottom of the upper shell (11) is provided with an assembly hole (111) for accommodating the toggle switch (2), the shifting rod (3), the micro switch (4) and the PCB (5), and the top of the upper shell (11) is provided with a first switch outlet (112) for extending the top end of the toggle switch (2); toggle switch (2), driving lever (3), micro-gap switch (4) and PCB board (5) are installed in pilot hole (111) from top to bottom in proper order, lower casing (12) match be fixed in the bottom of last casing (11) and cover the under shed of pilot hole (111).
7. The novel compact bi-directional rocker button switch for automotive interiors of claim 6, characterized in that: hinge holes (222) on two sides of the top opening of the key base mounting hole (221) are semicircular holes (2221) for vertically placing hinge shafts (211); shaft limiting ribs (113) are arranged on two sides of the lower port of the first switch outlet (112) and are matched with the distance between the hinge holes (222) on two sides of the top opening of each key base mounting hole (221); the hinge shaft (211) of the key (21) covers the semicircular hole (2221) through the shaft limiting rib (113) to limit the radial movement of the key.
8. The novel compact bi-directional rocker button switch for automotive interiors of claim 6, characterized in that: the top of casing (1) still matches and cup joints a panel (6), second switch export (61) that correspond with first switch export (112) phase-match are seted up on the top of panel (6), and the top of switch (4) stretches out after passing first switch export (112) and second switch export (61) in proper order.
