Switches
tolerate the extreme thermal and electrical stresses associated with high inrush switching over its rated operational life.
Maintaining the panel seal for repeated use
The JWLW series requires a rectangular cutout of 30.7 mm x 20.5 mm. Their snap-in design simplifi es the assembly process, requiring no additional mounting hardware. However, the precision of this cutout is critical for both mechanical stability and the integrity of the IP67 seal.
The switches accommodate a panel thickness from 1.0 mm to 4.0 mm, and are suitable for use with various panel materials, including sheet metal and moulded plastics. The switch bodies feature fl exible retaining tabs that compress upon insertion and expand behind the panel for secure locking. Their rocker actuator has a defi ned angle of throw of 26°, providing a tactile and visual indication of the switch’s state. The actuator has a nominal operating force of 10.00 N for the double-pole JWLW models. This force is enough to prevent accidental actuation while remaining comfortable for intentional operation.
The housing and frame are made of polyamide, the rocker of polyphenylene ether, and the case of melamine. NKK lists these switch materials as meeting UL94V-0 flammability requirements. This certification is an important safety metric for components used in mains-powered equipment.
Conclusion
The selection of a human-machine interface component, such as a power switch for high-reliability systems, is a complex decision that goes beyond current and voltage ratings.
The NKK JWLW series 16 A rocker switches offer direct switching of rated AC loads, provide a defined DC rating for telecom applications, handle transient inrush currents through their TV-8 rating, and help preserve functional integrity in harsh environments. For engineers designing a rugged operator interface, this combination reduces the number of trade- offs between power switching, mechanical integration, and environmental protection.

Antaira launches 32-port layer 3 fibre backbone switch with 100 W PoE++ and 10G uplinks
A
ntaira Technologies has introduced the LMP-3228G-4X24S-bt-T, a 32-port managed Layer 3 Ethernet switch
designed for industrial networks requiring fibre aggregation, high-power PoE and 10G backbone connectivity. Targeted at applications including utilities, water treatment, oil and gas, transportation and surveillance, the switch combines fibre networking, PoE and routing capabilities in a single ruggedised platform.
The switch features 24 Gigabit SFP ports for fibre connectivity and four 1G/2.5G/10G SFP+ uplink ports to support high-bandwidth backbone connections. Four IEEE 802.3bt PoE++ ports provide up to 100 W each, enabling power delivery to devices such as PTZ cameras, wireless
access points and industrial edge equipment. Layer 3 functionality includes support for OSPF and VRRP, while ITU-T G.8032 ERPS provides ring protection with recovery times of less than 50 ms. Additional networking and
security features include VLAN, QoS, IGMP, 802.1X, HTTPS and SSH.
Designed for industrial environments, the switch operates over a temperature range of -40 °C to 75 °C and incorporates redundant power inputs as well as EFT and ESD protection.
