What are Interlock Switches ?
Interlock Switches are safety devices designed to prevent machinery operation when certain conditions are not met. They are commonly used in industrial applications, including production electronics assembly and maintenance. Key specifications for selection include Actuator Type, which determines the method of operation; Current Rating (Amps), which ensures compatibility with electrical systems; and Ingress Protection, which indicates the switch's resistance to environmental factors. Validating lifecycle status and sourcing options is crucial for procurement teams to mitigate risks.
