Thru-Hole DIP Switches SERIES 79A Linear Action Circuit Selector SERIES 79C Linear Action Tap FEATURES • Single-Setting Programming • Isolated or Bussed Circuits • 10 or 16 Positions • 125 mA, 6 Vdc, 2000 Cycles DIMENSIONS Circuit Selector Tap Switch Isolated Circuits in 10 and 16 Positions Each position is a single isolated circuit, which connects the two terminals across the switch package. The movable contact is non-shorting. SP/10 Positions, and SP/16 Postions All contacts on one side of the switch are internally bussed for a common pole. Any terminal on that side may be used as a common, the others may be clipped. The movable contact is non-shorting.
