• Rail industry and transportation applications What are solenoid interlock switches used for? Solenoid interlock switches are widely used in machinery where an interruption could cause damage. This kind of switch mechanism is crucial when operating machinery where the hazard continues even after the power supply to a device is stopped – for example, when using circular-saw blades. Solenoid interlock switches are also used where there's regular entry to dangerous areas, such as high-temperature or pressurised sites.
