NKK Switches MS Miniature Slide Switches

NKK Switches MS Miniature Slide Switches provide smooth and accurate control in a compact package and come in a flat frame or bracketed PC mounting type. These switches feature an over-center actuator block and plunger for crisp actuation and a clear indication of circuit status. This construction design also diminishes sparking and increases operating life, with up to 50,000 or 100,000 minimum mechanical operations. The antijamming function protects contacts from damage due to excessive downward force on the actuator. Additional protection is provided by the high internal barriers between the poles and the insulating sheet between the case and actuator block. NKK Switches MS Miniature Slide Switches feature epoxy-sealed terminals to prevent the ingress of flux, solvents, and other contaminants. These switches are well-suited for audio/visual equipment, medical devices, and industrial control panels.
