The Series 53, 57 and 59 Style HS, Rotary
Switches have been tested to make and break
the following loads as stated in MIL-DTL-3786/36:
70,000 ft. altitude for 10,000 cycles: 10mA,
28 Vdc, inductive (250 mH); 50 mA, 28 Vdc,
resistive; 20 mA, 115 Vac, resistive. Atmospheric
pressure, 125°C for 10,000 cycles: 25 mA,
28 Vdc inductive (250 mH); 75 mA, 28 Vdc,
resistive; 50 mA, 115 Vac resistive. Atmospheric
pressure, 25°C for 10,000 cycles: 75 mA,
28 Vdc, inductive (250 mH); 250 mA, 28 Vdc
resistive; 150 mA, 115 Vac, resistive. Life limiting
criteria for these loads are:
Contact Resistance: 50 milliohms maximum.
Dielectric Strength:

Insulation Resistance:

Additional Characteristics
CyCLES x 1,000
Curve data based on test data conducted at
sea level, 25°C and relative humidity. Cycle
equals 360° rotation and 360° return. Cycling
rate is 10 cycles per minute. The curves shown
are typical load life curves for a Series 53M,
57M and 59M Rotary Switch. They show the
number of cycles of rotational life that can be
expected for the voltages, currents and types
of loads shown. Thus, with a 250 milliamperes,
30 Vdc resistive load, 10,000 cycles of life can
be expected. Life limiting or failure criteria for
these curves are:
Rotational torque: 20-80 in-ozs., depending
on the number of poles per deck and the
number of decks.
Contacts:
Shorting or non-shorting wiping
contacts with over 100 grams of contact
force.
Shaft Flat Orientation:
Flat opposite
contacting position pole #1 (See Circuit
Diagrams).
Extended Studs:
Switches of 6 decks or
more have longer studs with extra stud nuts for
recommended double end mounting.
terminals:
Switch is provided with full
complement of base or position terminals
regardless of the number of active positions.
