IN GENERAL, CONTACTS ERODE MORE QUICKLY AS CURRENT OR VOLTAGE IS INCREASED AND POWER FACTOR IS DECREASED. THE DATA SHOWS ELECTRICAL LIFE OF SWITCHES TESTED UNDER ORDINARY ATMOSPHERIC CONDITIONS, OPERATED 60 TIMES A MINUTE WITH 60 CYCLES 250 VOLTS AC POWER HANDLING ON BOTH NORMALLY OPEN AND CLOSE CONTACTS. THE HIGH INRUSH CURRENT ENCOUNTERED IN LAMP LOADS AND IN MOTOR OR OTHER INDUCTIVE LOADS IS RESPONSIBLE FOR DECREASED LIFE UNDER SUCH LOADING. 1.2 SILVER CONTACTS (E2 OPTION) FAILURE CRITERIA CONTACT RESISTANCE >100 MILLIOHMS TEMPERATURE RISE > 30°C OVER AMBIENT 1.5 MECHANICAL LIFE ckef019 THE FOLLOWING INFORAMTION IS BASED UPON: 1) NON-IMPACT ACTUATION 2) ACTUATOR TRAVELING FROM FREE POSITI0N TO FULL OVERTRAVEL POSITION (OVERTRAVEL FORCE SHOULD BE LIMITED TO A MAXIMUM OF THREE TIMES THE OPERATE FORCE OF THE SWITCH FOR BEST MECHANICAL LIFE) Page 1 MM Series P/N 550B FAILURE CRITERIA FATIQUE OF INTERNAL SPRING BLADE CONTACT RESISTANCE >75 MILLIOHMS PIN TYPE: >100,000 CYCLES LEVER TYPE: >300,000 CYCLES 2.0 INITIAL VALUE 2.1 CONTACT RESISTANCE 6 VOLT DC @ 100 MILLAMPS 50 MILLOHMS MAX. 2.2 INSULATION RESISTANCE 100 MEGOHMS – ACROSS OPEN CONTACTS 100 MEGOHMS – POLE TO POLE 100 MEGOHMS – TERMINAL-TO-COVER 1000 MEGOHMS MIN. 2.3 DIELECTRIC STRENGTH VOLTS RMS @ 60 HZ. @ SEA LEVEL MEASURED ACROSS OPEN CONTACTS 5 PICOFARADS MAX. 2.4 CAPACITANCE VOLTS RMS @ 60 HZ. @ SEA LEVEL MEARURED ACORSS OPEN CONTACTS >250 V RMS 2.5 ACTUATION FORCE (grams) GG (OPTION) CRITERIA 140 GRAMS MAX TYPICAL RANGE 85 TO 142 GRAMS 2.6 RELEASE FORCE (grams) GG (OPTION) 28 GRAMS MIN 28 TO 65 GRAMS 2.7 DIFFERENTIAL MOTION (inches) .002 MAX .0005 TO .002 2.8 PRETRAVEL (inches) .200 MAX .005 TO .020 2.9 OVERTRAVEL (Minimum) (inches) .004 MIN .004 TO .010 3.0 TECHNICAL DATA 3.1 CONTACT GAP (inches) .015 NOMINAL PRODUCTION RANGE (.010 TO .015) 3.2 CONTACT FORCE 22 GRAMS ON NORM OPEN AND CLOSED CONTACTS 3.3 CONTACT TRANSFER TIME 1 TO 10 MILLISEC 3.4 CONTACT BOUNCE TIME 5 TO 6 MILLISEC 3.5 STEADY STATE HUMIDITY 240 HOURS @ 40 C AND 95% RH CR108 OHMS 3.6 SALT SPRAY SALT FOG 5% NaCI FOR 96 HOURS No Physical Damage 3.7 THERMAL SHOCK 5 CYCLES WITH 30 MINUTE EXPOSURE AT -25°C AND +85°C CR250 VOLTS 3.8 VIBRATION FATIQUE (LOW FREQUENCY) 10-55 hz, 1 MINUTE SWEEP CR
