ETD/ETA/ETS SERIES
TRI-STATE TYPE

PATENT NO.:	5065276(U.S.A.)
	47618
	4856189(U.S.A.)

FEATURES

With three state (1, open, 0) setting function, especially suitable for encoding/decoding of tri-state encoder/decoder integrated circuit to obtain more security codes than traditional two-state (1,0) operation. For instance, 9 bits with tri-state gets 19,683 (3⁹) codes, while two-state has 512 (2⁹) codes, gains 38 times more codes with a ECE tri-state DIP Switch.
Bottom sealed to ensure free of flux immersion during wave soldering.
All plastics are UL 94V-0 grade fire retardant.
Gold plated contact to ensure low contact resistance and tin plated terminals to prevent contamination during soldering.
Twin contacts designed to ensure stable contact.
Ideal for coding tele-communication, transceiving, remote control and burglar alarm systems which use integrated circuits with tri-state coding systems.
