An emergency stop switch, also known as E-stop switch, E stop switch, emergency switch, kill switch, or emergency button, emergency stop push button switch, it is a fail-safe control switch that provides safety for the machinery and for the person using the machinery.<\/p>\n

The following requirements are specified in the European standard: EN 418 and international standard: ISO13850. An emergency stop switch must be highly visible in color, label and shape to operate easily in emergency situations. So the button must be red mushroom head with symbol of arrow, EMERGENCY or STOP. The common sizes of mushroom head are 29mm, 30mm, 40mm or 60mm.<\/p>\n

The direct operation mechanism must be set on the NC contact and have the self-holding function. It needs a twist, pull, or key to release electrical contacts to allow machinery restart. <\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

An emergency stop switch is a safety mechanism used to shut off machinery in an emergency, when it cannot be shut down in the usual manner.<\/p>\n

The purpose of an emergency push button is to stop the machinery quickly when there is a risk of injury or the workflow requires stopping. It is intended to avert harm or to reduce existing hazards to people, machinery, or working, so people also says\u00a0safety push button switch or\u00a0push button\u00a0safety switches.\u00a0<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

Emergency stop button switch are a critical system component that protect the safety of both operators and machinery in a variety of emergency shut down situations. Emergency stop buttons are wired in series with the control circuit of machinery equipment. When pushing the mushroom head of emergency stop button will break the circuit of machinery equipment and removes power supply.\u00a0(Extended learning:\u00a0What is the principle of the push button switches?<\/a>)<\/p>\n

The release of emergency stop button requires pulling, rotating, or using key, under strict authorized operation to ensure people and equipment safety to avoid injury again. Ingress protection of common e stop button is IP54, but the\u00a0waterproof emergency stop button can reach IP65 or IP67.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

4.\u00a0How many types is the emergency stop switch?<\/strong><\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

There are three kinds of the most common emergency stop switches, according to the action mode of the actuator. Pull release: The actuator is pushed in to stop and released by pulling the actuator back. Twist release: The actuator is pushed in to stop and released by twisting the actuator. Key release: The actuator is pushed in to stop and only released with a key.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

\n\t\t
\n\t\t\t

The emergency stop push buttons can be found in any industry including industrial, commercial and public facilities. They are required to be clearly visible to anyone that is required to use them. It is also possible to have several emergency stop buttons on one machine depending on what part of the machine has to be stopped. For example,\u00a0elevator, packaging machine, lift equipment.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
