A safety interlock switch is a device which keeps guard doors and gates securely locked to prevent access to areas where dangerous machinery may be in operation, minimalising the risk of injury to personnel and damage to machinery. They can also be used to monitor the status of the machine guard, and to ensure that machinery cannot start up or run while the guard door is open. They are often utilised in industrial applications, such as safeguarding factory production lines. They can vary in lock type, maximum current and voltage, and housing material. Safety-rated interlock switches are specifically designed to meet high machine safety standards. Allen Bradley Guardmaster switches are built to global standards to provide exceptional quality and reliability.
