-WR Series: http://www.nkkswitches.com/series.aspx?stid=2&id=5045
-WB Series: http://www.nkkswitches.com/series.aspx?stid=3&id=5016
The WT, WR and WB series switches are engineered to meet the needs of applications requiring a robust solution fit for use outdoors and in other harsh environments. The addition of wire leads to these devices increases their durability and ensures an even longer operational lifetime.
Each of these series is designed with single unit construction for added protection from harsh elements and also fully conform to IP67 of IEC60529 standards to be dust tight and provide protection from temporary water immersion. These devices are constructed of heat resistant resin meeting UL94V-0 flammability ratings and the newly added wire leads are sheathed with heat resistant vinyl in accordance with UL 1015 and CSA TEW 105 Standards for Appliance Wiring Material.
The WT Series of environmentally sealed toggles is rated at 10A @ 125V AC and 6A @ 250V AC or 10A @ 30V DC. They can be specified in single or double pole models. The bushing features both an inner and outer sealing ring. Bushings are also constructed with an anti-jamming design, protecting contacts from damage due to excessive downward force. Mechanical life for maintained circuits is 50,000 operations minimum, 30,000 operations minimum for momentary circuits. Electrical life is 15,000 operations minimum for all configurations.
The WR Series of environmentally sealed rockers is rated at 15A @ 125/250 AC and 15A @ 30V DC and is offered in single pole. Mechanical life is rated at 30,000 operations minimum for all circuits. Electrical life is rated 15,000 minimum for maintained circuits and 10,000 operations minimum for momentary circuits. Agency approvals include UL and C-UL Recognition, VDE and EN conformity.
The WB Series of environmentally sealed pushbuttons is rated at 6A @ 125V AC and 3A @ 250V AC or 6A @ 30V DC and is offered in single pole. Mechanical life is rated at 30,000 operations minimum. Electrical life is rated at 15,000 operations minimum.
