NKK's dual seal waterproof toggles include the M series and the S series. These switches offer highly reliable, double layer waterproof IP-rated construction. The major advantage of these toggles is an all-in-one rugged toggle switch with a silicone rubber boot integrated into the body of the switch and double seal protection to further ensure security against wet environments. The sleek design incorporates functionality with a polished, chrome-plated actuator. Both have an IP68 rating, protecting against immersion of 5 cm up to 1.5 m, and is salt spray tested per MIL-STD-810G section 509.5.

The M series toggle is miniature, designed for use in high-density boards.

The S series dual seal waterproof toggle is available in ten configurations with electrical capacity ranging from 15 A at 125 V_AC, 6 A at 250 V_AC, and 20 A at 30 V_DC.
