Case study

防止のメカニズム

Wiring to the probe can prevent the spring from breaking or melting.

下やじるし

The current flows only on Route C. This is possible because the probe body (shaft) consists of a single component on its own.

The current-flow on Route C would not switch onto Route D. The reason for this is that the current-flow cannot be disturbed by any friction of plural components.

In other words, any disturbance of contact resistance would not exist on the path of current-flow so that the current cannot be forced to flow in the spring nor break the spring.

This wiring method is also effective for precise measurements.

＜NOTE＞
It may happen that the current flows into the spring if the flow of the current was beyond the capacity of the probe in amount.
