Description

[Detailed description of the invention] The present invention relates to an automatic light-off switch.

Figure 1 shows a conventional automatic light-off switch A. This automatic light-off switch 8 has a built-in oil tassico hot (4:ll) in the inner bottom of the bore, and a see-saw operating hand li.

51) VC Yo? +It is a mechanical device that takes a delay. The oil tarrush pot (43) is provided with a main yoke (46) and a return yoke (4η), and a hole head (4η) that can be rotated freely by a shaft (54) at the end and that sucks the lower end of the armature (481). (B)). Magnets 3-9) (50) are provided on both sides of the permanent magnet (51). (The state is a cover, 145) Fi Miss sleeve (58) The cover (55) is an assembly frame.

The oil container (1 is filled with oil, and the oil is movable for 5 years.) In the position shown in Figure 1, the permanent magnet (51), A magnetic path is formed between the yoke α9), the return 3-way (47), the plunger, the main yaw 90 (support), and the magnet 3-way, and the hole bed (44) and the armature (481 are attracted).
, the contact that is driven at armour-1'P14 (to) is turned on or off. Next, when you operate the handle (52), the magnetic path, the permanent magnet (51), and the magnetic yoke 0.
9), Main yoke ¥46), Zu':) Formed into the head (44) and armature near (48). At this time, it moves to the side of the hedge (44), but the movement is delayed by the oil. Therefore, the contact point of the armour-prenear decoy is turned off or turned on after the suction is delayed. The conventional lifting platform uses a permanent magnet (51), and a handle (52).
The problem was that the operating load was heavy and it was difficult for children to operate it. Well, since the delay element used was an oil tarash hot 03), the internal oil viscosity changed depending on the ambient temperature, the delay time changed greatly, and the repeatability error was also large, resulting in a delay of just one. There was a problem in that the time was fixed and its uses were limited.

The present invention has been provided in view of the above points, and it is possible to obtain a delay time in a multiplex manner and to make the delay time variable.
Above the T-cod lift board with electronic components mounted, there is a switch mechanism that drives the automatic lights-out mode llI21 that obtains a delay time by opening and closing contacts by operating the handle. It provides a switch.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The contact section is opened and closed by reversing the operation, and since it is a single unit, the connecting mechanism section, the lint board, the support plate, and the switching mechanism section can be mounted in high density in the vertical direction, making the whole compact. In other words, the size of the hodge can be made large enough to accommodate two large square joules, and the delay time can also be formed using conventional mechanical methods. However, since it is composed of electronic circuits such as semiconductor switches and diode elements, the delay time is, for example, 0 to 5.
It can be varied by several minutes, providing a highly versatile effect. Furthermore, the contacts of the switch mechanism can be opened and closed using the handle.
) The movable terminal plate is reversed in a see-saw manner by the ball biased by the screw, which has the effect of simplifying the structure.
