LS-1900

LS-1900T

With large float displacement,
switch withstands rough
service; is suitable for high
viscosity liquids.

Resists build-up of foreign
material or sticky media. Float
travel remains uninhibited in
viscous or corrosive liquids.

LS-1950E
Exceptionally accurate and
rugged for higher temperatures
and in pressurised or corrosive
liquids. For oils, water and
chemicals.

LS-74780
Particularly well suited for rough
service. Ideal for use in chemical
and plating applications.
