Definitions3.1 Turn Signal SwitchA turn signal switch is that part of a turn signal system by which the operator of a vehicl
9、ecauses the turn signal lamps to function.3.2 Class A Turn Signal SwitchA Class A turn signal switch may be used on any vehicle but is intended for useon multipurpose passenger vehicles, trucks, and buses that are 80 in or more wide overall.3.3 Class B Turn Signal SwitchA Class B turn signal switch
10、is intended for use in passenger cars,motorcycles, and multipurpose passenger vehicles, trucks, and buses of less than 80 in overall width.4. Reference Standards4.1 The following sections from SAE J575f (April, 1975) are a part of this standard:Section BSamples for TestSection CLamp BulbsSection DLa
11、boratory FacilitiesSAE J589b Revised OCT77-2-4.2 Turn signal pilot indicatorsSee SAE J588c (September, 1970).5. Temperature Test5.1 To insure basic function, the switch shall be manually cycled for 10 cycles at design electrical load at: 75 10F (24 5.5 C); 165 +0, 5 F (74 +0, 2.8 C); 25 +5, 0 F (32
12、+2.8, 0 C). This to be done after a 1hexposure at each of these temperatures. The switch shall be electrically and mechanically operable duringeach of these cycles.5.2 This same switch shall be used for the endurance test described in paragraph 6.6. Endurance Test Setup6.1 The switch shall be operat
13、ed with the maximum design bulb load stated by the switch manufacturer with theflasher not included in the circuit. Failed bulbs shall be replaced during the test.6.2 When the switch is provided with a self-canceling mechanism, the test equipment shall be arranged so that theswitch can be turned off
14、 by the self-canceling mechanism. Provision shall also be made for manual canceling.6.3 The test shall be set up to operate the switch for the prescribed number of cycles.One cycle shall consist of the following sequence of positions: off, left turn, off, right turn, off.The test requirement shall f
15、unction within the following mechanical timing requirements at a cycle rate of 1220cycles/minute:Travel time0.10.5 s max (time from one position to the next position)Dwell time0.4 s min (in each position)6.4 During the test the switch shall be operated at 6.4 V d-c for a 6 V system, 12.8 V d-c for a
16、 12 V system, or25.6V d-c for a 24 V system, measured at the input termination of the switch. The power supply shall notgenerate any adverse transients not present in motor vehicles and shall comply with the followingspecifications:a. Output CurrentCapable of supplying a continuous output current of
17、 the design load and inrushcurrents as required by the bulb load complement.b. RegulationDynamicThe output voltage shall not deviate more than 1.0 V from zero to maximum load (includinginrush current) and should recover 63% of its maximum excursion within 5 ms.StaticThe output voltage shall not devi
18、ate more than 2% with changes in static load from zero tomaximum (not including inrush current), and means shall be provided to compensate for static inputline voltage variations.c. Ripple VoltageMaximum 300 mV, peak to peak.7. Endurance Requirements7.1 Class A turn signal switches shall be capable
19、of meeting the following endurance requirements:a. 165,000 cycles at 75 10 F (24 5.5 C).b. When the switch is provided with a self-canceling mechanism it shall be tested as follows:155,000cycles of self-canceling followed by 10,000 cycles of manual canceling.SAE J589b Revised OCT77-3-c. If the turn
20、signal switch includes stop lamp circuitry, the stop lamp circuit shall be fed electrically for thefirst 100,000 cycles only.7.2 Class B turn signal switches shall be capable of meeting the following endurance requirements:a. 100,000 cycles at 75 10F (24 5.5C).b. When the switch is provided with a s
21、elf-canceling mechanism it shall be tested as follows:95,000cycles of self-canceling followed by 5000 complete cycles of manual canceling.c. If the turn signal switch includes stop lamp circuitry, the stop lamp circuit shall be fed electrically for thefirst 50,000 complete cycles only.7.3 If the tur
22、n signal switch includes cornering light circuitry which is fed from the headlight switch, the corneringlight circuit shall be fed electrically for the first 50,000 cycles only.7.4 The voltage drop from the input terminal of each circuit to the lamp terminal of each circuit shall be measuredat the b
23、eginning of the test and at intervals of 25,000 cycles.This voltage drop shall not exceed:0.25 V for 2 lamp load (or less) per side0.30 V for 3 lamp load per side0.35 V for 4 lamp load per side0.40 V for 5 lamp load (or greater) per sidebefore, during, and after the endurance test.If wiring is an in
24、tegral part of the switch, the voltage drop measurement is to be made including 3 in of wire oneach side of switch; otherwise, measurement is to be made at switch terminals. Care shall be taken not toinclude the voltage drop of other devices in the circuit.8. Combination Turn Signal And Hazard Warni
25、ng Signal Switches8.1 The same combination switch shall be used for the test of each function. The turn signal switch function shallmeet the requirements of this standard. The hazard warning signal switch function shall meet therequirements of SAE J910b (June, 1971).8.2 The operating motion of the h
26、azard warning signal switch function shall differ from the actuating motion of theturn signal switch function.9. NotesThis document has been adopted by the Department of Defense.
