If you run machinery but haven’t installed E-stop buttons you certainly like to play Russian roulette with your safety and that of your workers. No machinery is 100 percent fault-proof; stuff happens. At one time or another, you may need to kill the engine quick due to a faulty or worn-out component or program that puts the operator’s health and safety in jeopardy. That’s where an E-stop button otherwise known as an emergency stop switch or kill switch comes in handy.

E-stop switches are required in almost every machinery. It depends on the country's regulations and the risk assessment report that establishes the kinds and levels of hazards associated with the machine's operations. Most countries require E-stop switches on equipment with high hazard levels to kill operations in case of emergencies.

These switches typically feature mushroom heads and red color for visibility and safe and convenient operations. Here’s a look at some of the most sought-after emergency buttons from APIELE:
