Ultra Subminiature Basic Switch
Subminiature Models Capable of
Large-capacity Loads
Snap-action switch allows large-capacity switching
(7 A at 250 VAC) in spite of its small size
(8.9 12.7 5.1 mm).
Particularly suitable as control switches for
applications where there are restrictions on
installation space and weight.
Easy positioning, as the pin plunger is located in
alignment with the center line of one of the two
mounting holes.
