NKK Switches Large Bushing Miniature Pushbutton MBN15SB3W01-DA

The MBN15SB3W01-DA is a miniature pushbutton switch from the Series M, designed for momentary or alternate action with silver contacts rated at 3A at 125V AC and 2A at 250V AC, or 0.4VA maximum at 28V AC/DC for logic-level applications. It features a threaded splashproof B3 bushing with IP67 sealing, a .335" (8.5mm) diameter, and solder lug terminals. The actuator uses an over-center mechanism to reduce sparking and extends life, while the diallyl phthalate case (UL94V-0) and epoxy-sealed terminals enhance insulation and environmental protection. Operating temperature ranges from -30°C to +85°C, with a mechanical life of 50,000 operations and an electrical life of 25,000 operations for silver contacts. The mounting torque is 0.7Nm for a single nut, and the plunger travel is 0.071" (1.80mm) for screw-on caps.
