Note
An address switch of the smallest possible dimensions is installed for reasons of space
saving. This makes it sensitive to pressure and objects with sharp edges. Always use a
suitable tool to manipulate the address switch.
A variety of tools suitable for activating the address switch are available on the market, for
example, the Grayhill DIPSTICK. A ballpoint pen may be employed if used carefully. It is
imperative to avoid any burring that would prevent the switch from reaching its home
position. Do not use screwdrivers or knives to manipulate the address switch.
