* Operation indicator attachment type classification
M900 series limit switch is generally composed of the product with operation indicator and without operation indicator.
Also divided into the a.c type and d.c type operation indicator.
It can be used as an operation indicator just by changing the cover of limit switch.
It does not need the separate connection and it selects ON/OFF by rotating the holder 180 degree.
