Talk station for intercom network

A communication station for an intercom network, the station comprising:

• a housing with a housing front and a housing rear side,
• a plurality of programmable operating elements,
• a plurality of displays on the housing front, the operating elements being selection buttons, the communication station, as a result of an operator actuating a selection button, providing a direct listening and/or speaking connection to a selected other communication station of the intercom network via an exchange station,
• a plurality of ports on the housing rear side,
• at least one loudspeaker or a port for a loudspeaker fixed on the housing front,
• a microphone and/or a port for a microphone on the housing front,
• a selection button manually shiftable only linearly in a first direction starting from a middle position into a first working position or alternatively shiftable in a second direction opposite the first direction into a second working position,
• a spring or magnet biasing the selection button toward its middle position, and
• a volume-adjustment element rotatable independently of movement of the respective lever, the selection button comprising or spanning over the rotatable adjustment element.

A communication station for an intercom network, the station comprising:

• a plurality of operating levers of which one is manually shiftable only linearly in a first direction from an inactive middle position into a first switching position or shiftable in a second direction opposite the first direction into a second switching position;
• a magnet biasing the one lever toward its middle position, the magnet exerting high forces up on the one lever when close to the middle position, the forces being effective on the one lever to displace the one lever toward its middle position;
• and
• a spring element separate from the magnet that biases the one lever toward the respective middle position.
