Stainless Steel Tongue Interlock Safety Switch, 3NC/1NO, 1/2 NPT

This tongue interlock safety switch is designed for machine guards in food processing, pharmaceutical, packaging, and petrochemical operations. It mounts at the leading edge of sliding, hinged, or lift-off guards to help support guard safety functions when the actuator is removed.

The switch has a 316 stainless steel body, three normally closed contacts, one normally open contact, and a 1/2 NPT connection. Its head rotates to provide four actuator entry positions. A double-seal lid gasket and seals support IP69K enclosure protection, and the safety contacts are forcibly disconnected when the actuator is withdrawn. Overall dimensions are 2.28 in. wide x 3.85 in. deep x 1.33 in. high.

Key Features:

• 316 Stainless Steel Body: Provides a rugged enclosure for demanding industrial environments.
• IP69K Enclosure Protection: Supports high-pressure detergent washdown applications.
• Forced Contact Disconnect: Helps provide a positive safety-contact disconnection when the actuator is removed.
• Four Head Positions: Allows the actuator entry direction to be adjusted for guard installation needs.
• Anti-Tamper Mechanism: Helps discourage unintended bypassing of the interlock function.

Choose this safety switch for sliding, hinged, or lift-off machine guards where stainless steel construction, washdown protection, and flexible actuator entry are required.
