Key switch (double-blade) Eti-Polam D5 model 001102173

Eti-Polam D5 double-blade key switch is a mechanical, keyed control device intended for use in electrical control and safety systems. The switch features two blades (two-wing) allowing reliable on/off switching and authorized access locking in industrial and commercial installations. It is designed for mounting in control panels and machine enclosures where physical key-operated control is required for safety interlocks and restricted operation.

Advantages

The double-blade mechanism provides distinct switching contacts for improved reliability and clear separation of circuits. As a mechanical key switch, it offers intuitive operation without the need for programming or power to change position. The compact form factor supports integration into existing control panels and enclosures, and the keyed operation prevents unauthorized use, enhancing safety and process control.

Suitable for

• Control panels in industrial automation
• Machine interlocks and safety circuits
• Access control for restricted equipment
• Manual override and authorised on/off switching

Key specifications

• Type: mechanical key switch with double-blade (two-wing) contacts
• Operation: key-operated on/off switching and locking
• Mounting: panel/desk mounting compatible with standard cutouts
• Contact arrangement: two separate switching blades for circuit segregation
• Actuation: removable or fixed key operation for controlled access

How to use

Install the key switch into the appropriate panel cutout and secure it according to the enclosure manufacturer’s instructions. Wire each blade’s contact terminals to the corresponding control or safety circuits, respecting correct polarity and ratings of connected devices. Use the key to change the switch position to enable or disable the controlled circuits; remove the key if required to lock the switch in a given position and prevent unauthorised operation. Verify correct function after installation by checking continuity and intended interlock behavior before placing the equipment into service.

Usage recommendations

Use the switch within the electrical ratings of the connected systems and in environments consistent with mechanical key-operated devices. Regularly inspect mechanical parts and contact points for wear, and replace the component if key operation becomes stiff or contacts show signs of degradation. Follow relevant safety and lockout/tagout procedures when integrating the key switch into safety-critical circuits.
