Cautions
1.To prevent the wear and the space should be within 1mm between the key and middle of the insert hole.
2.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.
Forced Disconnecting Mechanism
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.
