* 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.
