A solenoid interlock switch is a type of safety switch with an internal solenoid; a wire coil which converts electrical energy to mechanical. This type of interlock mechanism prevents access to hazardous areas where machinery is in motion by ensuring that that safety barriers remain securely locked. The guard can only be released through either energising (Power to unlock) or de-energising (Power to Lock) the solenoid with an external signal. They are often used in industrial environments, for example with high inertia rotating machines.
