Technical content

The 51W FormC Series consists of a mercury switch and operates without switch bounsing. This series is suitable for applications requiring stable contact resistance and high carry current capacity. The dielectric strength between contacts is rated 1KV as a standard catalog item, and ideal for applications requiring a higher degree of dielectric strength. We also provide a wide range of support to high -load environment. The switch configuration shown here is Form C.
