The Cla-Val Model X105L/X105L2 Limit Switch Assembly is a
rugged, dependable and positive acting switch assembly actuated
by the opening or closing of a Cla-Val control valve on which it is
mounted. The single pole, double throw micro switch can be
connected either to open or to close an electrical circuit when
actuated. By loosening the allen screw on the actuating collar and
raising or lowering the collar on the stem, the X105L is easily
adjusted to signal that the valve has fully reached the desired
position (open or closed).
