Why Choose the ILME SQ1643 Switched Socket 16A 110V 3 Pole IP44?
The ILME SQ1643 is a robust interlocked switched industrial socket-outlet designed for low-voltage power distribution in workshops, factories, construction equipment and industrial installations. Rated at 16 A and designed for 100–130 V AC supplies, including nominal 110 V applications, it provides a safe and dependable connection point for compatible industrial plugs.
The SQ1643 uses a 2P+PE three-pole configuration with a 4 h earth contact position and yellow voltage identification in accordance with the IEC/EN 60309 industrial connector system. An integrated mechanical interlock prevents the switch from being turned on unless a plug is inserted and prevents the plug from being withdrawn while the switch is in the ON position, helping improve operator safety during connection and disconnection.
Designed for flush or panel mounting, the SQ1643 is supplied without a backbox and provides IP44 protection. For wall-mounted installations, the compatible ILME SQC 1114 CS backbox can be added separately. Its self-extinguishing thermoplastic construction, spring-loaded socket cover and lockable switch control make it a practical choice for demanding industrial environments.

Safer Industrial Power Connections with Mechanical Interlocking
The ILME SQ series combines an industrial socket and isolation switch with a mechanical interlocking system. The interlock prevents the switch from being moved to the ON position when the plug is not inserted and prevents the plug from being removed while the switch remains ON. This provides a controlled connection and disconnection sequence for industrial electrical equipment.
The SQ1643 also features a lockable switch control and spring-loaded socket cover, while its IP44 and IK08 ratings provide protection for typical industrial environments. As the socket is supplied without a backbox, it is suitable for direct panel or switchboard integration, while the separately available SQC 1114 CS enclosure enables wall-mounted installations where required.
Typical Applications
- 110 V industrial power distribution systems.
- Factories, workshops and manufacturing facilities.
- Construction and maintenance equipment supplies.
- Industrial control panels and distribution boards.
- Machine building and OEM electrical systems.
- Portable tools and low-voltage industrial equipment.
- Commercial and industrial installations requiring interlocked socket outlets.
