Miniature Surface Mount
Transfer Switches
RLC Electronics’ miniature surface mount transfer switch
combines high performance in a compact configuration. The
switch provides extremely high reliability, long life, and
excellent electrical performance characteristics in a minia-
ture package. The power consumption is less than half that
of the miniature connectorized switches. The switch is
available with a choice of four different operating frequen-
cies and three coil voltages.
