General
Switch rating for break before make contacts.
Voltage: As listed in the chart.
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:
Contact Resistance: 50 milliohms maximum
(20 milliohms initially).
Insulation Resistance: 1,000 megohms
minimum between mutually insulated parts.
Voltage Breakdown: 500 Vac minimum
between mutually insulated parts. These
switches will carry 4 amperes with a maximum
contact temperature rise of 20°C. If the life
limiting characteristics are less critical than
those shown above or if elevated temperatures
or reduced pressures are involved, Grayhill can
predict the switch life for the application.
Electrical Ratings
Military Qualified
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: 500 Vac (350 Vac—
reduced pressure).
Insulation Resistance: 1,000 megohms
minimum. These switches also meet MIL-DTL-
3786/36 for moisture resistance, medium and
