In industrial production, the emergency stop switch can ensure that the workers in the operation is the body and life safety, the principle of the emergency stop switch has become a topic of concern to the netizens, only the workers know the principle of it, in order to better go to work. Therefore, in the design of some machines with transmission parts must be added to the emergency stop button this function. For the safety of the staff, and to be set up in the personnel can be easily pressed on the surface of the machine, there can not be any shade exists, the following rabbit will introduce you to the principle of its work.
Emergency stop button switch principle"Emergency stop switch" is usually a manually controlled press switch (button for red), press the locking rotary release red mushroom head button switch or round button switch (there are emergency stop switch to facilitate the operation of the LED lights installed), series access to the control circuit of the equipment, used in emergencies to directly disconnect the power supply of the control circuit so as to quickly stop the equipment to avoid abnormal operation. Avoid abnormal operation. It belongs to the main control appliances, when the machine is in a dangerous state, through the emergency stop switch to cut off the power supply, stop the equipment operation, to protect the safety of people and equipment.
Ordinary emergency stop button switch installation instructions
Insert the operating head from the panel into the mounting holes in front of the panel, after the panel is screwed into the center seat, and then uniformly tighten both ends of the setscrews (do not force too much, the maximum torque of 25N-cm), such as the panel of plastic and other non-metallic, can be mounted on the panel after the pad on the back of a piece of mounting plate and then installed, such as mounting holes in the diameter of 25mm, can be mounted on a φ25 pad behind the panel, can be installed on the back of the panel. If the diameter of the mounting hole is 25mm, it can be mounted after putting a φ25 mounting plate on the back of the panel.
Type A pushbuttons, the switching element can be installed together with the center base. Type B pushbuttons, the switching element should be removed first, and then the center base should be installed.
Note: If you find that the button is stuck after installation, you should adjust the two set screws in the center seat and keep them loose or tight, then you can clear it.
Switching elements can be fastened directly, the head of the symbol piece can be installed directly in the front (usually installed in the factory)
Note: After installation, you should check whether the switching elements of the buckle is completely fastened.
Removal of the switching element or buck: Use a screwdriver to lift the buckle of the locking mounting system, you can easily remove the components that have been tightly mounted
