This trapped key unit isolates power to machinery when the coded key is removed, ensuring that personnel cannot access dangerous areas where machinery may be in motion. This unit is perfectly designed for safety applications which require a pre-defined sequence of operations to access machinery. This type of reliable mechanical interlocking device is usually used in environments where electrical interlock systems may be unsuitable or expensive to install and maintain, such as areas with explosive atmospheres.
