SPECIFICATIONS
Electrical Rating
Rated: To make and break 125 mA at 30 Vdc
resistive at standard conditions
Life Expectancy: 25,000 cycles at rated load;
50,000 cycles mechanical. For ratings at different
loads and conditions, contact Grayhill.
Contact Resistance: 100 milliohms maximum
(50 milliohms initially)
Insulation Resistance: As measured between
mutually insulated parts
Initially:
50,000 megohms minimum
After Life:
10,000 megohms minimum
Voltage Breakdown: 500 Vac between mutually
insulated parts
Carry Current: These switches will carry 3
amperes with a maximum contact temperature
rise of 20°C.
OPTIONS
Shaft and Panel Seal
Shaft is sealed by o-ring inside the bushing;
panel is sealed by o-ring at the base of the
bushing. Seals do not alter dimensions as
shown in the drawing when switch is mounted.
Panel seal is silicone rubber. Shaft seal is an
o-ring per MIL-P-5516B. Shaft and panel seal
is not available on adjustable stop switch.
Additional Characteristics
Rotational Torque: 8 to 16 oz-in.
Contacts: Non-shorting wiping contacts
Shaft Flat Orientation: As shown in the drawing,
switch would provide a decimal 1 output.
Materials and Finishes
Base: Diallyl per MIL-M-14
Rotor Mounting Plate: Thermoplastic.
Rotor Contact: Phosphor Bronze, gold-plated
30 microinches minimum
Terminals: Brass, gold plate (20 microinches)
minimum over silver plate (300 microinches)
minimum
Additional Materials: Other switch materials
and finishes are the same as listed for the
standard switch. See Standard Switch.
Adjustable Stop Switches
Adjustable stop switch lets you limit the number
of positions. Remove and relocate pins in the
front plate. A sticker holds the pins in place.
With the exception of holes in the front plate, all
dimensions, ratings, and characteristics are
the same as the other Series 71 coded switches.
For diagrams, see Standard Switch.
