The K-2 2E and K-3 2E magnetic contacts are designed for flush mounting in wood or plastic. Place
the contact and magnet facing each other (Fig. 5 – as shown by the example of S-3). To make holes
for the magnetic contact elements, use a ø9 mm drill. Press the K-2 2E magnetic contact elements or
screw the K-3 2E magnetic contact elements into the holes made.
Notes:
Do not use a hammer to drive the contact into the hole (it may damage the reed switch).
When screwing the K-3 2E contact into the hole, the wires become twisted. To prevent them from
damage, twist the wires against the direction of screwing before installation.
