The present invention relates to the structure of a push button switch, and more particularly, it is possible to prevent the occurrence of defects during operation of the push button switch for industrial equipment, which is used for small-sense detection or the display function for each elevator floor of medium and high rating. As a structure, the number of parts can be reduced to reduce the manufacturing cost.

In the conventional push button switch, as shown in the EL, the terminal 3b is inserted into the lower end of the main body 1a, and the terminal switch 11 and the sliding piece 12 which are slid sequentially are provided on the upper part of the terminal 3b. A spring 13 is inserted between the inner side of the main body 1a and the upper portion of the moving piece 12 to impart an elastic force when the moving piece 12 slides, and is guided to an upper side of the main body 1a. A protrusion 14 is formed so that the operating lever 15 is connected to the moving piece 12 and hinged, and the back cover 16 is fixed to the rear of the main body 1a.

Accordingly, as the movable lever 12 is hinged to the upper side of the main body 1a of the push button switch and pressed downward in the state shown in FIG. At the same time as the sliding on the 3b), the terminal switch 11 in the moving piece 12 is slid to be located on the terminal (3b), the desired operation is made, if the force applied to the operating lever 15 is removed, the home position Done.

However, such a conventional pushbutton switch has a complicated structure, which requires a large number of parts, which leads to a high manufacturing cost, a large number of defects in operation, and inability to perform an efficient function as a switch at a fixed rating. There were a lot of issues.

The present invention is to solve the above problems, the present invention can not only improve the reliability by preventing the occurrence of defects during the operation of the push button switch for industrial equipment, but also reduce the manufacturing cost by reducing the number of parts as a simple structure And to provide a structure of the push button switch that can increase the productivity.

In order to achieve the above object, the present invention provides a main body in which first and second insertion holes and fixing grooves are formed, and fixed and attached contacts are inserted into and fixed to the first and second insertion holes and are connected and spaced apart. It is a structure of a push-button switch consisting of a movable terminal and a cover which is hinged to the main body to open and close, and a cover which is formed by an operation piece for lowering and connecting a contact by pressing a fixed hook coupled to a fixed groove when closed.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4 of the accompanying drawings.

Figure 3 is an exploded perspective view showing the present invention, Figure 4 is a longitudinal cross-sectional view showing the operating state of the present invention, the first and second insertion hole (2) (2a) is provided on both sides of the lower part in the main body (1) of the pushbutton switch A fixed terminal 3 having a contact 3a attached to an upper surface thereof is inserted into and fixed to the first insertion hole 2, and a protrusion 4 formed at a lower portion of the main body 1 in the second insertion hole 2a. ) Is connected to the elastic piece 5 to protrude downward, and the movable terminal 6 having a contact 6a corresponding to the contact 3a of the fixed terminal 3 attached thereto is inserted and fixed.

In addition, the cover 7 is hinged to an upper end of the main body 1, and fixed to one end of the main body 1 when the cover 7 is closed on the main body 1 at one end of the bottom of the cover 7. A fixing hook 9 is formed to be coupled to the groove 8, and the upper and lower portions of the cover 7 protrude and descend as the protrusions are pressed to lower the contacts 3a and 6a of the fixed and movable terminals 3 and 6. The elastic force operating piece 10 which connects and energizes) is formed and comprised.

The present invention configured as described above has the first insertion hole 2 in the first and second insertion holes 2 and 2a formed on both lower sides of the main body 1 of the pushbutton switch, as shown in FIGS. A fixing terminal 3 having a contact 3a attached to an upper surface thereof and fixed to the upper surface thereof, and an elastic piece 5 connected to the projection 4 formed at the lower part of the main body 1 in the second insertion hole 2a. ) Is protruded downward to insert and fix the movable terminal (6) attached to one end of the contact (6a) corresponding to the contact (3a) of the fixed terminal (3).

Then, by closing the cover 7 hinged to the upper end of the main body 1 to engage the fixing hook 9 formed on one end of the bottom of the cover 7 to the fixing groove 8 of the lower side of the main body 1 Assembly is completed as shown in (a) of FIG.

Accordingly, the fixed and movable terminals 3 and 6 inserted into and fixed to the first and second insertion holes 2 and 2a formed on both sides of the lower part of the main body 1 of the push button switch as shown in FIG. When pressing the resilient operating piece 10 protruding in the upper and lower center of the cover 7 in the state that the contact (3a) (6a) of the spaced apart off, the operating piece 10 is lowered, As shown in (b) of FIG. 4, the operating piece 10 presses the movable terminal 6 so that the contact 6a of the movable terminal 6 and the contact 3a of the fixed terminal 3 are connected to the push button switch. Is operated, and when the force applied to the operation piece 10 is removed, the push button switch is returned to the off state as shown in FIG.

On the other hand, by using a light emitting diode (LED) in the main body (1) of the push button switch, it is possible to facilitate identification when using the push button switch to provide convenience.

As described above, the present invention can prevent the occurrence of defects during the operation of the push button switch, and can reduce the number of parts by reducing the number of parts as a simple structure, as well as increase the productivity, so the efficiency and reliability of the switch It is a very useful design that greatly improved.
