Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a switch structure for a portable electric light used in general homes and indoors.

Conventional Technology In the past, the switch structure of this type of portable light required turning the lens frame and moving the lens frame forward and backward through screw fitting to turn the switch on and off. However, in this case, there was no click feeling when operating the switch, and the ON and OFF positions were unclear.

Problems that the invention aims to solve Accordingly, in such a conventional configuration, the ON and OFF positions were unclear, so there was a problem that the electrical contact would become unstable if the switch was stopped at an appropriate position.

This invention solves these problems,
The purpose is to provide a click feeling at the normal ON/OFF position of the switch, making it clear when switching electrical contact.

Means for Solving the Problem In order to solve this problem, the present invention screws the case and the lens frame, and by advancing and retracting the lens frame, the conductive member and the socket are brought into contact and separated. At the same time, a protruding piece and a spring for biasing it are arranged on a part of the outer periphery of the case so that it moves back and forth, and two recesses are provided at positions corresponding to the protruding pieces on the outer periphery of the lens frame, so that the switch can be moved. ON,
It is designed to give a click feeling when the switch is turned off.

Effect With this configuration, when the case and the lens frame are screwed together, the projecting piece protrudes from the case and fits into the recessed part of the lens frame with constant rotation, creating a click feeling (when OFF). Further, when the lens frame is turned in the direction in which the screw advances, the protruding piece protrudes and fits into the next recess, producing a click feeling (when ON). At that time, the socket comes into contact with the conductive member and the miniature bulb lights up.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. In the figure, reference numeral 1 denotes a case, in which a conductive member 2 is disposed and a power source battery 3 is housed. Reference numeral 4 denotes a lens frame, and the lens frame 4 houses a lens 5, a reflecting mirror 6, a socket 7, and a miniature bulb 8. Furthermore, a protruding piece 9 is arranged on the outer circumference of the case 1 on the screw side, and a spring 10 urges the protruding piece 9 to be pushed out. A cover 11 prevents the protrusion 9 and spring 10 from popping out. In addition, the lens frame 4 corresponding to this projecting piece 9
Two recesses 12a and 12b are provided on the outer periphery. Next, the operation will be explained. When the lens frame 4 is screwed into the threaded portion of the case 1, a removable projecting piece 9 provided on the case 1 fits into the recess 12a of the lens frame 4, producing a clicking sound. At this stage, the switch is in the OFF state. Furthermore, case 1
When rotated in the forward direction, it fits into the recess 12b of the lens frame 4 at the second location and produces a clicking sound. At this time, the conductive member 2 and the socket 7 come into contact and the switch is turned on. Thereafter, when the lens frame 4 is turned to the opposite side and moved back, the first recess 12a fits into the protrusion 9 provided on the case 1, making a clicking sound and turning off the switch.

Effects of the invention As described above, according to the invention, the switch can be moved forward and backward by screw fitting between the case and the lens frame.
When turning ON and OFF, it makes a clicking sound, and the concave part of the lens frame fits into the protrusion on the case, so the ON and OFF
The effect is that the switching can be performed reliably.
