The DowKey 260 Series is a standard DPDT switch with six connectors, allowing two of four straight-through paths from two inputs. The 260B is identical in construction, except that there is an internal connection between the N/C contacts, leaving only four connectors. The 260B Series is widely used to insert or by-pass a circuit element (such as an amplifier or filter) in a transmission path between two normally connected elements. Both are available with a choice of actuator coils, connector options, and a pair of form "C" auxiliary contacts.
Typical applications for the 260 Series include:
- Inserting a Linear Amplifier Between an Exciter and an Antenna
- Filter, Attenuator, or Amplifier By-Pass Switching
- Insert Filters or Attenuators in a Transmission Path
- Dual Simultaneous Transmit/Receive or Antenna Switching
