Switches
Würth Elektronik expands its switch program. The popular SMT-mountable short-travel push-button switches are now joined by a new size version: the “WS-TASV SMT Tact Switch 4.5*3.2 mm”. The switches are available in three versions with different actuation forces. The range of power switches is expanded with a rocker switch for a particularly space-saving device panel cut-out. The short-travel push-buttons from Würth Elektronik are suitable both for switching functions on and off as well as for use as signal transmitters.

CABLES & CONNECTORS
Compact Surface-Mount SMB Jack
Amphenol RF introduced a new high performance surface-mount straight SMB jack into their broad portfolio of SMB connectors. With a true surface-mount footprint, this connector is designed with four gold-plated ground tabs that solder directly to the board for superior coplanarity and automated pick-and-place handling. This 50 Ohm jack features a drop-in footprint which makes it well-suited for industrial control modules, test and measurement equipment, avionics and military electronics equipment.
