Problems solved by technology

If the peripheral touch-sensitive reed 70 is kept on the side wall 20a, a failure may occur in the connection of the peripheral touch-sensitive reed 70 when the multi-directional switch is toppled and restored.
[0015] Furthermore, in the multi-directional switch described above, it is necessary to wire the common contacts around the central touch-sensitive reed so that each central touch-sensitive reed and each peripheral touch-sensitive reed are in constant contact with the common contacts respectively, thus hindering Miniaturization of Multidirectional Switches in the Width Direction
[0016] In addition, touch-sensitive reeds have a large number of parts and are troublesome to assemble, so they cannot be supplied cheaply

Embodiment Construction

[0043] Such as figure 1 and figure 2 As shown, the casing 1 is made of synthetic resin and is formed into a roughly rectangular shape by molding, which includes side walls 1a around the periphery, an inner bottom 1b surrounded by the side walls 1a, and a slit protruding from the inner bottom 1b to the inner side of the inner bottom 1b. And the two protrusions 1c facing each other, and the opposing protrusions 1d protruding from the pair of side walls 1a respectively. In addition, at the four corners of the side wall 1a, a flat wall 1e is formed by so-called chamfering.

[0044] In addition, on the inner bottom 1b of the housing 1, the circular central fixed contact 2, the common contacts 3 arranged on the relative positions surrounding the central fixed contact 2 and the front, rear, left, and right sides surrounding the central fixed contact 2 are exposed. The circular perimeter holds the contacts 4 in four positions. These central fixed contacts 2 , common contacts 3 an...

Abstract

A multidirectional switch including a housing having disposed at an inside bottom portion thereof a central fixed contact, a common contact, and a plurality of peripheral fixed contacts; and a plurality of metallic movable contact springs disposed so as to oppose the central fixed contact and the peripheral fixed contacts, respectively. In the multidirectional switch, the movable contact springs are always in electrical conduction with the common contact, the movable contact springs being connected by a metallic connecting portion in order to form an integral structure. In addition, by operating an operating rod, at least one of the movable contact springs is brought into electrical conduction with the opposing central fixed contact or the corresponding one of the peripheral fixed contacts.

Description

technical field [0001] The present invention relates to a multi-directional switch that outputs a switching signal corresponding to the tilting direction of a mast, and in particular relates to a multi-directional switch that also outputs a switching signal through a mast pressing operation. Background technique [0002] Existing multidirectional switch is described with reference to accompanying drawing. [0003] Figure 8 is a sectional view showing a conventional multidirectional switch, Figure 9 It is a plan view showing the casing of a conventional multidirectional switch, Figure 10 It is an exploded oblique view showing the casing and movable contacts of a conventional multidirectional switch, Figure 11 It is an explanatory drawing explaining the operation of the conventional multidirectional switch. [0004] Such as Figure 8 to Figure 10 As shown, the housing 20 is made of synthetic resin and is formed by forming, and it includes a side wall 20a around the per...
