Description

  The present invention relates to a push button switch device used for switch operations of various electronic devices, and more particularly to a lateral push type push button switch device.

  In recent years, due to the configuration of electronic devices, there is an increasing demand for a lateral push type push button switch device that performs a switch operation by moving an operation piece in parallel with a printed wiring board surface. Further, along with the downsizing and thinning of electronic devices, there is a strong demand for a small and thin projection area and excellent mountability.

  1 and 2 show the configuration of a conventional lateral push type push button switch device. 1 shows a push button switch device having a one-stage switch structure in which a circular dome switch (4) is arranged on the bottom plane of the housing (10), and FIG. 2 shows a circular dome switch (4 ) Is a pushbutton switch device having a one-stage switch structure arranged on the side surface of the housing (10).

  As shown in FIG. 1, the conventional side-push type push button switch device is configured such that when the operation piece (1) is pushed into the housing (10), the tip of the operation piece (1) is moved in the direction change guide (2 ) And the operation piece (1) is further pushed into the housing (10), the traveling direction of the tip of the operation piece (1) changes to the arrow direction (A) shown in FIG. The dome switch (4) arranged on the plane (10) is pressed. Further, as shown in FIG. 2, when the operation piece (1) is pushed into the housing (10), the tip of the operation piece (1) is arranged on the side surface of the housing (10) ( 4) has a structure to press down. In the push button switch device shown in FIG. 1, since the dome switch (4) is arranged on the plane of the housing (10), the entire device is made thinner than the push button switch device shown in FIG. Is possible.

  In recent years, functions of various electronic devices are diversified, and the number of pushbuttons of a pushbutton switch device for operating electronic devices equipped with various functions tends to increase. For this reason, there is a push button switch device to which a two-stage switch structure as shown in FIG. 3 is applied.

  In general, it is technically difficult to reduce the shape of the dome switch, so in the two-stage switch structure shown in FIG. 3, the smaller second-stage dome switch (42) is made smaller. As a result, the shape of the larger first-stage dome switch (41) becomes larger. Therefore, generally, when the two-stage switch structure shown in FIG. 3 is applied to the position of the dome switch (4) shown in FIGS. 1 and 2, the shape of the first-stage dome switch (41) is used. As a result, the shape of the housing (10) shown in FIGS. 1 and 2 becomes large. Therefore, in the push button switch device to which the two-stage switch structure shown in FIG. 3 is applied, the thickness of the entire push button switch device or the shape of the push button switch device is increased.

  In addition, the push button switch device to which the two-stage switch structure shown in FIG. 3 is applied, presses the first stage dome switch (41) arranged in the housing (10) at the tip of the operation piece (1). When the first-stage dome switch (41) is closed, a click feeling is always generated. For this reason, if the two-stage switch structure shown in FIG. 3 is applied to an electronic device that is to be thinned and miniaturized, a material of concern such as camera shake is generated. Therefore, in the pushbutton switch device to which the two-stage switch structure shown in FIG. 3 is applied, it is difficult to switch the two-stage switch with high accuracy.

Thus, there is a push-on switch excellent in automatic mountability (see, for example, Patent Document 1).

  In addition, the operation body 27 in which the contact pressing portion 27A and the operation portion 27B are integrated as a block is disposed on the elastic movable contact 24 accommodated in the inner bottom surface 21B of the switch base 21 that is inclined so that the front is lowered. The upper base plate portion 26A that covers the entire switch base 21 from above the operation body 27 and guides the contact pressing portion 27A in the direction of pressing the movable contact 24 during the pressing operation of the operation body 27 has no gap 26. There is a push-on switch that has a small projection area, is thin, and is excellent in automatic mounting (see, for example, Patent Document 2).

Alternatively, there is a small and multi-functional push button switch device that is composed of a circumferential protrusion 15d that presses and connects the lower center contact 12b and the upper center contact 13c and a projection (see, for example, Patent Document 3). ).

  Further, in the operation button device in which the moving member is connected to the operation button so as to be able to reciprocate, and one switch is operated by the tip surface of the moving member, a protrusion is formed at a location excluding the tip surface of the moving member, There is an operation button device in which another switch related to the one switch is provided in the movement region of the protrusion (see, for example, Patent Document 4).

In the pushbutton switch that operates the first-stage switch element by the first stroke movement of the operation member and operates the second-stage switch element by the second stroke movement longer than the first stroke, The switch element is provided on the side wall of the case, and the second-stage switch element is provided on the bottom surface of the case.
