- Use attention affair
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.
