NKK Switches MB2000 Series Miniature Pushbutton Switches & Accessories
NKK Switches MB2000 Series Miniature Pushbutton Switches offer interlocked actuator block which prevents jamming by maintaining correct alignment, these pushbutton switches use an over-center actuator mechanism, which diminishes sparking and increases operating life in AC circuits. MB2000 series switches have epoxy-sealed terminals that prevent the entry of solder flux and other contaminants. These miniature pushbutton switches find applications in optical instruments, medical machinery, and metal cutting machines. Accessories and hardware for MB2000 series product lines including caps, knobs, bat levers, boots, and protective guards.
Features
- Clinching of the frame to the case well above the base and terminals provides 1500V dielectric strength
- Epoxy-sealed terminals block solder flux and contaminants
- High torque bushing construction prevents rotation or separation from the frame during installation
- Interlocked guide and actuator block prevent window locking, maintaining plunger alignment for contact stability
- Molded in a diallyl phthalate case, high insulating barriers enhance circuit isolation in multiple devices.
- Prominent external insulating barriers increase insulation resistance and dielectric strength
- The high torque bushing construction prevents rotation or separation from the frame during installation
- Utilizing an over-center actuator mechanism reduces sparking and enhances operational lifespan in AC circuits
