An interlock switch is a safety component that prevents machinery from operating when safety barriers or doors are open. It ensures that hazardous areas are not accessible during machine operation, protecting operators from injury.
The switch is mechanically actuated when a door or barrier is closed, completing an electrical circuit that allows machine operation. When opened, the circuit is broken, stopping the machine or preventing startup. Positive-break contacts ensure fail-safe operation.
Rated voltage is 24 V DC, rated current is 10 A, contact resistance ≤100 mΩ, mechanical life 1,000,000 cycles, electrical life 100,000 cycles, operating temperature -25 to 70°C, IP67 protection, actuation force 10-20 N, positive opening force ≥50 N. These are reference values; verify with the manufacturer.
The switch references IEC 60947-5-1 for control circuit devices, IEC 60529 for degree of protection, and UL 94 for flame retardance. These standards are for verification; compliance must be confirmed with the supplier.
