Double Ridge Solenoid Actuated Fail-Safe Waveguide Switch

 The Waveline series of solenoid actuated switches are lightweight, high quality devices intended for remote controlled switching applications.  Flange faces on these devices are 90 degrees apart in either the standard DPDT (4 port) or SPDT (3 port) versions.  Standard -77 series switches are of the fail-safe design, which require holding current in position #2 (energized0.  Removal of power or a power failure to the drive circuit returns the switch to position #1 (de-energized).

  The switches are made of aluminum with balanced rotors mounted in high precision ball bearings for rapid switching and long life.  All standard switches incorporate interlock circuitry to indicate rotor position or to switch other equipment.  Operating voltage is 28 VDC with low holding current required.  For other voltages or custom features, contact Waveline sales or engineering.  These switches can be pressurized upon request.  Alternate flanges and materials are available.  See flange section.  Finish is instrument gray enamel.
