The models SW 01, SW 02 and SW 03 are motor-driven, two-way coaxial transfer switches designed to change coaxial connections with a minimum off-air-time.

Mainly they are used for switching transmitters, antennas, dummy loads and other peripheral equipment in situations when broadcasting procedures are modified, when there is need for emergency repair, or during scheduled maintenance.

The coaxial switch provides two isolated RF paths for each switch connections. For prevention of any damage a couple of auxiliary microswitches are built in, that help the RF power throughout the switch to be removed just before the RF spring contacts start to open and also to be established again just after the RF contacts reach their final position.

The cavity has four ports terminated with 1 5/8inch aluminium as standard 1 5/8" EIA flanges including non-removable inner conductor connectors The assembly is not gas-tight. The switch is equipped with a mechanical position indicator and emergency knob for manual operating.
