Electrical Ratings
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
high shock, vibration, thermal, thermal shock,
salt spray, explosion, terminal strength and
stop strength.
