The fixed terminal is manufactured so that the power line can be directly connected to the fixed terminal by inserting the terminal 9 or through the soldering hole formed in the bottom of the lower casing 2.

The rotary type push switch intermittently rotates the movable terminal 6 by the carrier while the actuator 4 intermittently rotates as the push button 3 is pressurized and acts as a plurality of fixed terminals 8. It is to be used to make contact sequentially.

However, since the rotary push switch does not have a separate lighting device therein, it is very inconvenient for the driver to operate the rotary push switch at night.

In addition, the rotary push switch has a problem in that the push button is operated by a single return spring 5 so that a shock sound and an operation sound are severely generated during the push operation of the button, thereby causing inconvenience in use.

The present invention is designed to fundamentally solve all the problems of the above-described prior application technology and other prior art by the present applicant, and to easily operate the switch even at night by embedding the LED inside the housing to illuminate the LED, The purpose is to provide a convenient assembly, assembly and other components, such as to provide the ease of use, assembly productivity and product reliability by providing to minimize the generation of impact sound, operating sound when pressing the switch.

The purpose of this invention,

The upper and lower housings are assembled to each other, and the inner assembly hole of the upper housing is assembled with the knob and the plunger assembled under the push, the actuator, the return spring, and the movable terminal inserted into the carrier to press the knob according to the pressing operation. The movable terminal is grounded to the fixed terminal of the terminal inserted into the lower housing while intermittent rotation operation, the on and off operation;

Between the plunger and the actuator, and between the actuator and the carrier, respectively installed a bullet spring,

The inside of the upper housing is characterized in that the installation is installed by inserting the LED light that illuminates the illumination light into the transparent portion formed in the knob of the push button so as to check the position of the switch from the outside into the assembly groove formed in the upper portion of the lower housing.

The LED bulb is characterized in that the electric wire is inserted through the assembly hole of the lower portion of the assembling groove and fixed to be grounded by forcibly inserting into the assembling groove having the entrance portion of the "V" type on both sides of the terminal.

In addition, the separate resistor is characterized in that it is fixed to the ground by forcibly inserting both ground wires into the assembly groove having the "V" type inlet toward the outer side to one side position of the terminal.

The LED groove and the assembling groove into which the ground wire of the resistor is inserted are smaller than the diameter of the wire and the ground wire, respectively.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

That is, the rotary push switch of the present invention, as shown in Figures 3 to 8, while assembling the upper and lower housings 10 and 20 mutually, the knob in the inner assembly hole 11 of the upper housing 10 30 and the plunger 35 assembled below the push 31, the actuator 40, the return spring and the movable terminal 50 are assembled in the state in which the carrier 70 is inserted into the When the actuation of the actuator 40 causes the cam to actuate, the movable terminal 50 is intermittently rotated by the carrier 70 and grounded to the fixed terminal of the terminal 80 inserted into the lower housing. In

Between the plunger 35 and the actuator 40, between the actuator 40 and the carrier 70 is installed to be installed in a multi-stage buffer operation by respectively installing a spring spring 91, 92,

Inside the upper housing 10, an LED bulb 100 illuminating an illumination light with a transparent part 32 formed on the knob 30 of the pushbutton so that the position of the switch can be checked from the outside. Inserted and installed into the assembly groove 21 formed as,

In the assembly groove 21 of the lower housing to form a through hole 22, 22 penetrating downward,

The terminal 80 insert-molded in the lower housing 20 has an assembly hole 81 and 81 penetrating into the lower positions of the through holes 22 and 22 of the housing, and the inlet portions of the “V” type on both sides. The assembly groove 82 having the 82 'is formed to insert the wires 110 and 110 of the LED bulb 100 through the through holes 22 and 22 to force the assembly grooves 82 and 82. It is configured to be fixedly installed to be grounded by insertion.

In addition, the terminal 80 of the lower housing 20 is formed with an assembling groove 83 having an inlet portion 83 'having an “V” type toward the outside in one side position so as to face both ground lines of the resistor 85. (86) It is configured to be fixedly grounded by inserting the 86 from the outside to the inside.

At this time, the assembly grooves 82 and 83 into which the wires 110 and 110 of the LED bulb 100 and the ground lines 86 and 86 of the resistor 85 are inserted are smaller than the diameters of the wires and the ground lines, respectively. It is to form a ground and fixed installation by forcibly inserting the wire, the ground wire.

In addition, the transparent part 32 formed on the knob 30 is formed by partially peeling off the painted part of the knob.
