Restrict access to dangerous equipment with this interlock switch from Schmersal. You can use it to cut power to a circuit when a protective gate is open, reducing the risk of injury and other hazards in your work environment. For durability and strength, the switch's housing is made from a glass-fibre-reinforced thermoplastic material that's impact-resistant, giving you a long-lasting product. Screw termination lets you mount the switch quickly and securely without the use of any specialised tools, making installation simple.

• Compact dimensions of 90 (length) x 52 (width) x 30mm (depth) for use in areas where space is limited
• Wide operating temperature range of -20°C to +70°C for use in both hot and cold environments
• Silver conducts for high conductivity and corrosion resistance, ensuring a reliable connection even in demanding conditions

• Metalworking industry
• Construction applications
• Industrial machinery

The switch has an IP67 (ingress protection) rating, which means it can withstand submersion in up to one metre of water for up to 30 minutes. This makes it safe for use in areas where occasional exposure to moisture is likely.
