Description

[Detailed description of the invention] [Industrial application field] This invention relates to a multi-functional switch that can be used in motorcycles, motorboats, etc., and includes a rotary switch and two types of pressure switches in one casing. It is characterized by:

[Prior art]

As a conventional multi-function switch,
The engine switch for motorboats with an emergency stop function described in Publication No. 11566, and the
There is one equipped with a rotary main switch and a push switch as described in Japanese Patent No. 160435. The former has two functions: it has a switch function that causes an emergency stop by pulling out the cord held between the push button and the head, and it also has two functions that allow it to make an emergency stop by pressing the head while holding the cord. The latter was a switch with two functions: a rotary main switch and a push-button switch; there was no main switch with three switch functions.

[The problem that the idea attempts to solve]

However, switches for ships such as motorboats require a switch for stopping and an emergency stop switch in addition to the main switch, and conventionally, in order to provide these three functions, at least two
It was necessary to install two switches.

[Means to solve the problem]

This invention has one switch casing with
A rotary main switch, a first pressure switch with a removable lock plate, and a push-type second pressure switch are integrated.The first pressure switch is used for emergency stop, and the second pressure switch is It was made available for use in chiyoke.

〔Example〕

As shown in FIG. 1, the present invention has a compression coil spring 4 installed between the upper half of a casing 3 having a horizontal partition plate 2 with an opening 1 in the center and the top surface of the partition plate. As shown in FIG. 2, a horizontal elongated hole 7 is provided in the lower part thereof in a penetrating manner, and a cylindrical slider 8 is made airtight with an O-ring and is movable up and down. As shown in FIG.
The supporter 13 is airtightly provided with a ring so as to be movable up and down, and the supporter 13 is provided with a large-diameter plate-like portion 16 having two protrusions 19 on the upper part as shown in FIG.
A cylindrical drive shaft 18 with a vertical elongated hole 17 penetrating through the middle part is hermetically fitted with an O-ring, and the lower half thereof is placed below the opening 1 of the partition plate 2 in the center of the casing. Protruding supporter 1
3, and inside the drive shaft 18 is provided a shaft 22 with a horizontal pin hole 21 in the middle as shown in FIG.
A connector 26 having a movable contact 25 at its lower end is provided at the bottom of the casing and biased upward via a compression coil spring 27, and is connected to the horizontal elongated hole 7 of the slider 8 and the supporter. 1
A pin 30 is inserted and fixed into the pin hole 21 of the shaft 22 by passing through the rectangular hole 11 of No. 3 and the longitudinal elongated hole 17 of the drive shaft 18, and a movable contact 32 is attached to the lower end of the drive shaft 18. A rotor 31 for the rotary switch is provided with an action ball 33, and a fixed contact 34 for the rotary switch is provided at the bottom of the rotor 31.
A movable contact 2 at the lower end of the connector 26 is provided.
5 is provided with a fixed contact 35 of a first pressure switch that can be used for emergency stop, and a fixed contact 36 of a second pressure switch that can be used for a stop yoke is provided at the bottom of the supporter 13. A U-shaped lock plate 38 as shown in FIG. 6 is removably interposed between the lower surface of the head and the upper end surface of the slider 8, and a recess into which the projection 19 fits is provided in the upper part of the drive shaft 18. This is a waterproof multi-function switch which is covered with a cap-shaped key 40 having a key 39.

Note that a magnet 14 is embedded in the upper surface of the large-diameter head 12 of the supporter, and on the other hand, the key 4
A magnet 41 is also embedded in the lower surface of the 0, and the structure is such that the drive shaft 18 can be rotated when the two are aligned, but this key means may be of a cylinder lock type.

[Effect]

In the normal state shown in FIG. 1, when the key 40 is rotated, the rotor 31 at the lower end thereof rotates via the drive shaft 18, and the movable contact 32 of the rotor contacts the corresponding fixed contact 34, so that the rotary switch is turned on.
Turned on. At this time, the pin 30 is fitted into the pin hole 21 of the shaft 22 and the longitudinal elongated hole 17 of the drive shaft 18, and rotates at a certain angle together with the drive shaft. Since horizontal movement is possible within the hole 7, there is no problem in rotating the drive shaft through a certain angle.

Next, when the top of the key 40 is pressed down, the drive shaft 1
8 presses the compression coil spring 4 to release the supporter 1
3. It descends together with the lock plate 38 and slider 8. Along with this, the pin 30 also descends, so the movable contact 25 descends as shown by the two-dot chain line via the shaft 22 and the connector 26 and comes into pressure contact with the fixed contact 36, turning on the second pressure contact switch.

Next, when the lock plate 38 is pulled out from between the large diameter head 12 of the supporter 13 and the upper end of the slider 8, as shown in FIG.
As the slider 8 is pushed upward together with the pin 30, the shaft 22 through which this pin passes and the connector 26 at the lower part are also pushed up by the action of the compression coil spring 27 at the lower part, and the movable contact 25 is pushed up by the upper fixed part. The contact 35 is pressed and the first pressure contact switch is turned on.

At this time, when the pin 30 is raised, it is movable in the vertical direction within the rectangular hole 11 of the supporter 13 and the longitudinal elongated hole 17 of the drive shaft 18.
The movable contact 25 moves up together with the shaft 22 and the connector 26 without any trouble.

Therefore, if the rotary switch described above is used as a main switch, the first pressure switch is used as an emergency stop switch, and the second pressure switch is used as a stop switch, it can be used as a multi-functional switch for ships.

In the above embodiment, an O-ring is provided between each member to provide airtightness, but this O-ring is not necessarily required depending on the application.

[Effect of idea]

As mentioned above, the present invention integrates a rotary switch and two pressure switches on the upper and lower sides into one casing, and allows the two pressure switches to be activated by pressing the key or pulling out the lock plate. Although it has a switch function, it is compact and has high utility value as a marine switch and other multi-function switches.
