To designate the switch desired use:
1: “M” for Manual, “R” for Remote. 2: “3”, “4”, “5” or “6” throw operation 3: “A” for 115 Vac, “D” for 28 Vdc or “H” for 12 Vdc 4: “I” for indicators if desired. |
5: “L” for Latching cutthroat if desired 6: “TL” for TTL Driver if desired 7: “26” for 26.5 GHz options. 8: “40” for 40 GHz option |
Example: STR-3-D is a SP-3T, 28 Vdc, without indicators, failsafe switch
