Double Ridge Motorized Latching Type Waveguide Switch

    This series of motorized latching type waveguide switches are lightweight aluminum, high-quality devices intended for latching type remote controlled switching applications.
    The standard R.F. section is available as a DPDT (4 port) type with paths of the continuous arc design or optional SPDT (3 port).  The rotor is supported on low friction ball bearings.  Rotor clearance in the  housing is such that a temperature rise due to high power loading (R.F.) will not cause binding in the R.F. section.
    Latching type switches are actuated by applying power to a common terminal and a position terminal.  When units are latched in position, no current is drawn.  The alternate position is achieved by applying power to the common terminal and the alternate position terminal.
    The drive section utilizes a modified Geneva linkage and brushless type motor for smooth, dependable operation.  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.
