One cycle is 360° rotation clockwise and 360°
return. The data for the curve was measured at
sea level, 25°C and 68% relative humidity with
the life limiting criteria which follows.
Contact Resistance: 100 milliohms maximum,
(15 milliohms initially).
Insulation Resistance: 10,000 Mohms
minimum between mutually insulated parts
(50,000 Mohms initially).
Voltage Breakdown: 600 Vac minimum
between mutually insulated parts at standard
atmospheric pressure.
Life Expectancy: As determined from the
load-life curve for the current to be switched.
Contact GRAYHILL for more information if any
of the following is true: the life limiting criteria are
more critical than those listed; longer operation
is required; a larger make and break current is
required; the operating environment includes

Panel is sealed by a flat rubber seal washer at the base of
bushing. Shaft is sealed by an
O-ring inside the bushing. After
the switch is mounted, seals do
not alter the dimensions of the
unsealed style.

Rotary Switches
Stop Arrangement: The suffix C or F must be added to a one
pole per deck switch with the maximum number of positions to
indicate continuous rotation (C) or fixed stops (F) between position 1 and the last position.
Type of Contacts: N = Non-shorting, S = Shorting
Positions Per Pole: 02 as a minimum to the maximum
allowable for the angle of throw and number of poles per the
Choices Chart. Use the letters AJ in this location if adjustable
stop switch is to be ordered.
Poles per Deck: Limited by angle of throw. See chart
