Switches
Single Deck Rotary Switches
SPECIFICATIONS
Military Qualification
The dimensions for qualified switches are
the same as those indicated in the drawings
of standard switches. Switches with standard
variations, such as shaft and bushing length,
which do not affect switch performance, can be
marked as qualified product. Contact Grayhill
for complete information on variations.
36°, 45°, 60°, 90° (Series 50): The C and M
style switches are qualified to MILS3786/20.
They include the following:
Solder lug or PC terminals
With or without panel seal
Series 50 qualified switches may be ordered
by the ‘M’ number or by the Grayhill part
number.
30° (Series 51): The C and M style switches
are qualified to MILS3786/35. They include
the following:
Solder lug or PC terminals
With or without panel seal
Series 51 qualified switches may be ordered
by the ‘M’ number or by the Grayhill part
number.
Additional Characteristics
Contact Type and Forces: Shorting or non
shorting wiping contacts with over 80 grams
of contact force.
ShaftFlatOrientation:Flatoppositecontacting
position of pole number one (see circuit
diagrams).
Terminals: Switches have the full circle of
terminals, regardless of number of active
position.
Stop Strength: 7.5 poundinches minimum
Rotational Torque: 8–24 ounceinches,
depending on the number of poles.
SPECIFICATIONS: Other
PROCESS SEAlEd–Style T
Switch can be mounted on PC board with other
components and subjected to wave soldering
and conventional board cleaning techniques.No
secondary wiring or soldering is necessary.
Bushing is oring sealed;epoxy potting seals the
terminals and the rear of the switch. Designed
for PC assembly, this sealing technique can also
be applied to solder lug terminal switches. A
bushing to panel seal can also be added to the
process sealed versions. Military qualified ver
sions are available, see ordering information.
Electrical Ratings
life Expectancy:With the limiting criteria stated
here, the Series 50 and 51 with nonshorting
contacts will switch the following loads at
atmospheric and reduced pressures for 25,000
cycles of operations. One cycle is 360° rotation
clockwise and 360° return.

Contact Resistance: 20 milliohms maximum,
(10 milliohms initially).
Insulation Resistance: 1,000 Mohms
minimum between mutually insulated parts.
Voltage Breakdown: 600 Vac minimum
between mutually insulated parts at standard
atmospheric pressure.
life Expectancy: Listed for the voltage source
and make and break current levels. 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
elevated temperatures or reduced pressures.
Contact Carry Rating: Switch will carry
6 amperes continuously with a maximum
contact temperature rise of 20°C.
