We have added a range of technical connections to each of our switch systems: from USB-C, RCA and HDMI to fibre optic (FO) and SAT. The central inserts have the usual shape and are each equipped with up to two connections, so-called "keystones". In addition to the combinations shown, you can also put together your own connections. If you only need one keystone, the hole for the second one is closed with a dummy plug. For an extra charge, we also offer a special support frame in which a single keystone can be placed in the centre. The universal cable outlet is ideal for applications that are not covered by the connections offered here. We will be happy to help you with any queries and the selection of suitable connections.
