Dry circuit - gold over nickel over brass.
RATING: 0.4 Volt-Amps (VA) max. at 20 V max.
ELECTRIC LIFE: 100,000 cycles min. (ST1-1 & ST2-1 only - other models 40,000 cycles min.)
Power circuit - coin silver.
RATING: 6 Amps at 125 VAC, 3 Amps at 250 VAC or 7 Amps at 30 VDC (resistive loads).
ELECTRIC LIFE: 100,000 cycles min. (ST1-1 & ST2-1 only - other models 40,000 cycles min.)
Dry circuit or power circuit - gold over nickel over coin silver.
RATINGS & ELECTRIC LIFE: Same as B & Q above - i.e. - can be used in either dry circuit or power circuit, however once used in power circuit,
switch cannot be re-used in dry circuit. This option satisfies those customers who have both dry circuit and power circuit requirements, but prefer
to inventory only one switch for both.
Dry circuit - gold over nickel over brass. Note- less gold than B option.
RATING: 0.4 Volt-Amps (VA) max. at 20 V max.
ELECTRIC LIFE: 10,000 cycles min. at 13 cycles per minute.
Power circuit - Silver plate over brass.
RATING: 3 Amps at 125 VAC or 1.5 Amps at 250 VAC (resistive loads).
ELECTRIC LIFE: 10,000 cycles min. at 13 cycles per minute.
Solder dipped terminals and custom
contact plating available - contact factory.
UL & CSA OPTIONS
UL
CSA
For power circuits - coin silver
RATING: 6 Amps at 125 VAC or 3 Amps at 250 VAC (75% power factor).
Underwriter Laboratories file no. E66367. To specify, order UL model no. Note - applicable only to terminations with coin silver contacts
(Q or G options).
For power circuits - coin silver
RATING: 6 Amps at 125 VAC or 3 Amps at 250 VAC (75% power factor). Canadian Standards Association file no. LR54592-1. To specify,
UL model number, then add '/CSA' to complete switch number. Note - applicable only to terminations with coin silver contacts (Q or G options)
as CSA recognizes switches for power applications only. Note- Double pole switches with solder lug terminals are not CSA recognized.
SEALING & MISCELLANEOUS OPTIONS
E
Epoxy terminal sealing: Available with all
terminal configurations.
The space between terminal & case hole
is sealed with epoxy all around terminal.
Provides maximum protection from entry of
flux or contaminants into the switch case.
/R To specify reverse switch action
on non-symmetrical models with bush-
ing keyway, add '/R' to switch model no.
Black finish is available on actuator,
bushing & hardware. To specify,
add '-22' to switch model no.
