Fastening of the switch cable
The switch bodies are filled with resin for sealing purposes. To avoid stressing the cable and switch body, fasten the switch at 5 cm or farther away from the switch body, should the wire be bent, the bending radius shall be at least 45mm.

Installation
The service life and accuracy of switches will be effected bythe shape of actuator operation frequency & over travel. So theangular of the fixing level should be about 30, the surface finishof the fixing level should be over, the hardness is from HV400~500.When installing, the position of the concave part should be abovethe standard panel

Contact types

Switch bank mounting
A maximum of six switches may be mounted together as a switch bank.During the installation,the convex part of the switch back.The mounting panel shall be 6mm or thicker.

Mounting
Recommended tightening torque according to the follwing form.

Mounting holes
Mount the switch body to a rigid mounting panel using two M5 screws.

Model	Screw type	Torque
1	M5 fastening screws	43.4~52lb.in (50~60kgf.cm)
2	M3.5 installing screws	6.9~7.9lb.in (8~9kgf.cm)

Use attention affair
To prevent the wear and the space should be within 1mm between the key and middle of the insert hole.

When in use,there should put a plate on the top to prevent the key overinsert.To prevent nonmovement ,the space between the plate and the switch should be under 3 mm.

Required to have positive machine

When the contact block get fire,press on the middle of the key structure, the NC strict leaving structure can push the contact block a way cut off the movement.
