FS: SP12T ceramic rotary switches ride again!
>From the debris field I laughingly call my "workshop", the last two SP12T
NOS switches surfaced like goosed dolphins. See below for more info.
If you're planning on building a Miracle Whippersnapper or other antenna(*), you'll
recall that the original design requires replacing a potentiometer's resistance
element with a toroidal inductor to make a variable inductance. If that's too much work,
consider using a multitapped toroid and a multicontact rotary switch such as the
Electroswitch p/n D4C0112N. As shipped, it's a SPDT switch, but you can configure
multiple poles (from 2 to 12) by bending tabs.
I'm offering NOS single-pole 1- to 12- position ceramic rotary switches. You can view a full description here: https://www.digikey.com/product-detail/en/electroswitch/D4C0112N/451-1087-ND/514141 They're kinda pricey from a distributor, but I'm offering these at $7.25 each plus postage ($4.30 for one switch, add $2.00 for the additional switch). Questions welcomed, PayPal honored. Thanks, and 73-- Brad AA1IP (*)...Or other portable antennas or tuners requiring switching a whole bunch of things, one at a time.
