Abstract
A multiway switching valve includes a valve member which is mounted in an internal compartment of a housing member for displacement between two terminal positions. The valve member is retained in each of the terminal positions by a respective magnet, especially a permanent magnet of an annular configuration which bounds a passage in which a magnetically attractable portion of the valve member is received in the respective terminal position. The housing and valve members are provided with abutments which abut one another in each of the terminal positions, the abutments being so located that the magnetically attractable portions of the valve member are out of contact with the housing member even in the terminal positions of the housing member. The magnetically attractable portions of the valve member are so dimensioned as to be spaced from the annular magnets even when the valve member assumes the terminal positions thereof.
