In general, an emergency pushbutton switch is installed in a workshop for operating various equipment such as precise and important machinery or large and high-speed automation equipment to quickly shut down the equipment in case of emergency. These emergency pushbutton switches are mainly installed on the exterior panel of the entire installation, so that the operator operates the switch in an emergency such as an emergency situation.

Such an emergency pushbutton switch has a cylindrical outer socket detachably connected to a switch contact socket electrically connected to the inside of a facility such as various kinds of machinery, and a cylindrical outer socket which is installed to be able to rotate forward and backward and a predetermined angle on the outer socket. Composed of an internal socket and a push button coupled to the end of the internal socket, when an operator presses the push button in an emergency, the internal socket moves forward to stop the operation of the equipment by cutting off the power of the switch contact socket. Then, when the operator rotates the push button pressed in one direction, the inner socket is retracted together with the push button. At this time, the inner socket is elastically retracted to its original position by the spring built in the outer socket. When the inner socket is retracted to this position, the switch contact socket is supplied with power to reset the equipment such as machinery. Can be

However, in the process of continuing work in the factory or taking measures for first aid, the switch is often operated with hands contaminated with oil or other foreign matters. When gripping and rotating, the hand slides around the pushbutton due to grease. Therefore, the conventional emergency pushbutton switch has a problem that the operator can not rotate the pushbutton pressed smoothly, it is inconvenient to return the pushbutton to its original position.

In addition, in the case of the conventional pushbutton switch, the front end portion of the external socket and the circumference of the internal socket are exposed to the outside, and there is no separate means for covering the gap between the external socket and the internal socket exposed to the outside of the facility. not. Accordingly, there is a significant disadvantage in that a malfunction such as a switch may not work properly due to penetration of foreign matter such as dust into the exposed gap between the outer socket and the inner socket.

On the other hand, according to the test criteria by spraying water to the external panel of the installation the push button switch is installed to test for a short circuit. However, as described above, the conventional pushbutton switch is not covered with a gap between the outer socket and the inner socket, and is exposed to the outside as it is, and malfunctions such as a short circuit of the mechanical equipment are generated while water penetrates into the exposed gap. There are many possibilities that can occur.

The present invention has been proposed in view of the problems described above, and the present invention provides an emergency pushbutton switch that facilitates the operation of returning the pushbutton to its original position when restarting after an emergency stop of an equipment such as a mechanical device. For the purpose of It is also an object of the present invention to provide a new configuration of the emergency pushbutton switch that can improve the reliability by significantly reducing the possibility of foreign matter such as water or dust penetrates in use.
