The smaller JWMW series features a panel cut out of 25 X 15.4 mm and is certified for TV-5. It has an electrical capacity of 10 A @ 125/250 VAC resistive and 10 A @ 30 VDC. Larger JWLW devices have a panel cut out of 30.7 X 20.5 mm and are TV-8 rated with an electrical capacity of 16 A @ 125/250 VAC and 5 A @ 72 VDC.
These devices have an exterior seal covering the flange that is an integral part of the switch. They are rated to IP67 of IEC60529 standard, which is similar to NEMA 4 and 6. An optional watertight boot is also available. Featuring UL, CSA, and VDE approvals, JWMW and JWLW switches also carry a flammability rating of UL94V-0.
All JW rocker switches are constructed for dust resistance with an interior polyphenylene sulfide seal between the actuator and contact area. These devices also feature prominent external insulating barriers which increase the insulation resistance and dielectric strength.
