51W FormC Series
PRODUCT DESCRIPTIONS
PCB Mount
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.
