Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lever switch in which a swinging switching operation of a switching operation lever is transmitted as a sliding switching movement of a slide switch to obtain switch switching.

As is known, the lever switch is constituted by a switching operation lever that is pivotally supported so as to be able to swing from an intermediate swing position.
It is arranged to obtain switching of the slide switch in its swinging position to one or the other by transmitting said swinging movement to the sliding switch, but in order to obtain a precise electrical switching of the slide switch. requires a mechanism to ensure the sliding stroke and sliding switching position of the slide switch.

Therefore, the present invention has a protrusion projecting from the side surface of the free end of the switching lever constituting the lever switch in parallel with the lever swing shaft, and connects it to the stroke setting window bored in the side plate of the frame for supporting the lever shaft. The switching position of the switching operation lever and the slide switch linked thereto can be set in one direction and the other direction from the intermediate swing switching position by simply inserting the switching lever and the slide switch linked thereto. By providing a switching position setting window and a switching position setting piece with a configuration of The purpose of the present invention is to provide a compatible lever switch that can be converted to a contact switching method.

The drawings show an embodiment of the lever switch according to the present invention.

In the figure, reference numeral 1 denotes a switching operation lever of a lever switch, and the lever 1 is interposed between both side plates 12 raised from both side edges of a bottom plate 13 of the frame, and has a swinging mechanism protruding from both sides of the lever. A roller 2, which is pivotally supported on both side plates 12 by a shaft 11 and retractably provided at the tip of the lever, elastically engages in a recess 21 formed in the bottom plate 13 as shown in FIG. The engaged position is an intermediate swing switching position of the lever, and the lever can swing between one swing switching position and the other swing switching position with the intermediate swing switching position as a boundary.

On the other hand, an arm 15 is protruded from one side of the operating lever 1, and is pivotally connected to a slide switch 16 supported by a frame, so that the arm 15 is slidably switched in response to switching of the lever to each position.

The switching operation lever is provided with a protrusion 17 parallel to the swing shaft 11 on the free end side extending from the swing shaft 11 toward the frame bottom plate 13, and supports the swing shaft 11 on the other hand. A swing stroke setting window 18 for the switching operation lever 1 is opened in one side plate 12.12 of the frame, and the protrusion 17 is opened.
The swinging stroke of the switching operation lever 1 is set by facing the swinging stroke setting window 18, and swinging regulating walls 18a and 18b are formed at both ends of the swinging stroke setting window 18, so that the switching operating lever The upper 4-piece abutment 17 that moves with the swinging operation of step 1, and the swinging stroke setting window 18
The collision with the swing regulating wall 18a at one end secures the swing switching position of the lever 1 in the one direction, and the collision between the protrusion 17 and the swing regulating wall 18b at the other end of the setting window 18 similarly secures the switching position of the lever 1 in the one direction. The structure is such that the swinging switching position of the lever 1 in the other direction is secured by the above-mentioned movement.

As described above, the swing stroke and swing switching position of the switching operation lever 1 are set, and these are transmitted to the slide switch 16, the sliding stroke and the sliding switching position are set, and accurate switch switching is achieved.

Further, there are two switching position setting windows 19' on the other side plate of the frame that can support the swing shaft 11 of the switching operation lever 1, allowing intervention of a tool such as a screwdriver.

20' is opened and the respective switching position setting windows 19', 20' are opened.
A switching position setting piece 19.20 whose one end is connected to the window sill inside.
extend.

The switching position setting pieces 19.20 extend in the switching position setting window from the connecting portion in the longitudinal direction of the switching operation lever 1 in the intermediate swing switching position. As shown in the figure, a space surrounding the switching position setting windows 19', 20' is left in the outer area surrounding the extending portion of the switch 20.

The switching position setting windows 19', 20' and the switching position setting pieces 19.20 are located at positions corresponding to both ends of the stroke setting window 18, respectively, and the switching position setting windows 19 and 20 are located at positions corresponding to both ends of the stroke setting window 18, respectively.
9' and the setting piece 19 are arranged on one side of the intermediate swing switching position of the switching operation lever 1, and the other switching position setting window 20' and the setting piece 20 are arranged on the other side. .

When either one of the switching position setting pieces 19, 20 is bent into the frame (inside the side plate) from inside the switching position setting window 19' or 20', the switching position setting piece 19', One side edge of the switching operation lever 1 is provided so as to abut against the side surface of the lever 1 on one side of the swinging direction at the intermediate swinging position of the switching operation lever 1. Alternatively, the structure is such that the swinging switch in the other direction is prevented.

The switching position setting windows 19' and 20' also serve as a guide for the tip of a tool such as a screwdriver as described above, and the window space surrounding the switching position setting pieces 19 and 20 is formed by the setting pieces 19.
Alternatively, it is possible to clearly confirm the correspondence between the lever 20 and the side surface of the lever 1 in the swinging direction, and to bend the lever from inside the window to the corresponding position.

That is, by using one of the switching position setting windows 19', 20' as a guide and using the window space surrounding the setting piece (especially the space at the tip of the setting piece) as a clue, pushing the tip of the tool, the setting piece 19 or 20 can be easily and properly bent from the connecting portion to the position where it collides with the lever at the intermediate swing switching position.

As a result, an intermediate swinging switching position with no play of the lever 1 is secured, and the purpose of preventing swinging in one direction from the same position is precisely achieved.

As a result, the lever switch can be easily and reliably converted from two-contact switching to two-contact switching, and conversely, by restoring the setting pieces 19 and 20, from two-contact switching to two-contact switching.

Furthermore, even when restoring the setting piece 19 or 20 that has been bent, the space around the windows 19', 20' in which the setting piece resides allows the restoring tool to be put in and taken out without any trouble.

Furthermore, the setting pieces 19.20 that freely reside within the windows 19' and 20' as described above can be easily bent without being interfered with by the window side walls, and similarly, when punching the setting pieces 19.20, For example, the normal extension position within the window can be ensured without causing deformation or inclination, or causing unnecessary interference with the lever due to inward displacement of the side plate, as would be the case when the setting piece is slotted. .

It is easy to cut out the strings.

Further, since the switching position setting pieces 19 and 20 extend from the connecting portion in the longitudinal direction of the lever in the neutral position, when the switching position setting pieces 19 and 20 are bent inward of the side plate 12, the lever 1
As a result, the load applied to the bending part (setting piece connection part) becomes a lateral force perpendicular to the bending direction, so even a thin setting piece can have a large lever support strength, and even if the lever 1 is repeatedly oscillated. , for example, no displacement occurs when the setting piece is bent in the same direction as the bending direction,
Provides normal and stable switching position setting action.

Further, since it is possible to cause the setting pieces 19, 20 to interfere with the lever 1 at a position as close as possible to the root portion (bending portion), the lever supporting force can be further improved.

As mentioned above, the present invention is extremely useful as a conversion mechanism for lever switches, and has a very simple structure, and can be manufactured by simply punching the frame during processing without adding any parts to the existing structure. It has the advantage of not increasing costs.
