Tips: What is a safety interlock switch?
A safety interlock switch is a switch that prevents access to a hazardous area until the danger is removed, or automatically removes a dangerous state once it is touched.
The safety interlock switch should contain two concepts: First, for safety. Second, it must be linked with equipment, machinery and other control devices.
Safety interlock switches are widely used in the field of industrial safety. A large number of hazards are exposed in the factory: rotating wheels, moving levers, etc. If there is no additional protection settings, workers are directly exposed to such hazards, which may lead to Industrial accidents. In order to avoid such accidents, you can choose to add additional protective devices, such as: using a protective cover to make in the form of a door to isolate the moving and rotating parts from the workers. This kind of safety door can effectively reduce the occurrence of accidents, but it is still unavoidable, because the protective device may still be removed or opened. In order to prevent such a situation, adding a safety interlock switch connected to the power switch of the equipment on the protective cover can achieve the following two functions:
- The equipment cannot be started when the safety door is opened or removed.
- When the equipment is running, once the safety door is opened, the equipment will stop directly.
