Cross switch Legrand SUNO 10 AX 250 V~ screw terminals white (model 721107)

Legrand SUNO cross switch 10 AX 250 V~ with screw terminals in white (model 721107) is an electrical accessory intended for intermediate or crossover connections in multi-way lighting circuits. It is designed to be incorporated into standard flush-mounted switch boxes and wiring systems to enable an additional switching point between two-way circuits. The switch complies with typical domestic and light-commercial electrical ratings and uses screw terminals for secure conductor fastening.

Advantages

This cross switch offers a compact design and a neutral white finish that integrates with common switch ranges. Screw terminal connections provide a stable mechanical and electrical connection for copper conductors, allowing reliable performance over repeated operation. The 10 AX, 250 V~ rating suits common lighting loads and ensures compatibility with incandescent, halogen, and many LED lighting fittings when used within the load limits. The device is intended for standard installation practices and is compatible with Legrand SUNO mounting frames and covers.

Suitable for

• Intermediate switching points in multi-way lighting circuits
• Residential lighting systems (hallways, staircases, corridors)
• Light-commercial interiors where an extra switch location is required

Key specifications

• Rated current: 10 AX
• Rated voltage: 250 V~
• Connection type: screw terminals for conductor fastening
• Color/finish: white
• Function: cross (intermediate) switch for multi-way circuits
• Mounting: flush-mounted switch boxes using standard frames

How to use

Install the cross switch as part of a multi-way lighting circuit by connecting the incoming and outgoing traveller conductors to the screw terminals according to the wiring diagram for intermediate switching. Turn off the mains supply before starting installation and verify circuit absence with appropriate instruments. Secure conductors under the screw terminals with the recommended stripping length, tighten screws to the torque specified in installation guidelines, and fit the switch into the frame and mounting box. Restore power and test all switch positions to confirm correct operation of the multi-way configuration.

Usage recommendations

Use this device only within its rated current and voltage. For LED and low-power lighting, ensure the total load does not exceed the 10 AX rating and follow manufacturer guidance for compatible dimmers or electronic control gear. If unsure about wiring or safety requirements, consult a qualified electrician and follow local electrical regulations during installation.
