ABSTRACT:
The invention contemplates an improved electric switch which changes its state via float response to achievement of a particular liquid level. The construction features mechanical seal and shield structure whereby liquid is kept out of the region of float guidance, with the result that float response is substantially isolated from sloshing action and from liquid contamination.
