Structure And Action
Below wire diagram for switch with key inserts & lock status. (Terminal 12 &41, 22&51, 32&61 is inside connection)
Product installation
| Releasing the 4 screws on top of the cap, spinning the direction of top cap until the suitable position for key inserting |  |
| When install on side hung door, it should be over than semidiameter. |  |
| Please install the safety switch door and insertion key under range 1-3.5mm. |  |
| The installation of operation key allows ±1mm error within the key insertion center of the hole. |  |
