Sealed Switches Suit Outdoor, Extreme Applications

NKK Switches has expanded its product offerings for industrial markets with the WT and WR series of cost effective, environmentally sealed toggle and rocker switches. Engineered to meet the needs of applications requiring an environmentally sealed and robust solution, the new switches conform to IP67 and IP60 of IEC60529 standards and are designed for use in outdoor and harsh applications.



Featuring single-unit construction for added protection from harsh elements, the WT and WR devices are constructed of heat-resistant resin, meeting UL94V-0 flammability ratings. Both the toggles and rocker versions incorporate a specially designed switching mechanism for breaking light welds, qualifying them to IEC 61058 (UL 61058-1).

These series of devices are available in a wide selection of circuit configurations, including maintained and momentary options. Both actuator alternatives are available with solder lug, screw and wire lead terminations. The wire leads are sheathed with heat-resistant vinyl in accordance with UL 1015 and CSA TEW 105 standards for Appliance Wiring Material (AWM). In addition, the WR series of rockers can be specified with quick-connect terminals to reduce and simplify assembly time.



The WT series is rated at 10A at 125VAC and 6A at 250VAC or 10A at 30VDC. Switches can be specified in single or double pole models. Physically, the bushing features both an inner and outer sealing ring and is constructed with an anti-jamming design, protecting contacts from damage due to excessive downward force. Mechanical life is 50,000 operations minimum for maintained circuits and 30,000 operations minimum for momentary circuits. Electrical life is 15,000 operations minimum for all configurations.

The WR series rocker switches are rated at 15A at 125V/250VAC and 15A at 30VDC and is offered in single pole configuration. Mechanical life is rated at a minimum of 30,000 operations for all circuits. Electrical life is rated at a minimum of 15,000 operations for maintained circuits and 10,000 operations minimum for momentary circuits.



Agency approvals include UL and C-UL recognition, VDE and EN conformity.
