SPECIFICATIONS
MIL-S-3786 Electrical Values
Military Style
Style M switches, at 85°C, approximately
68% humidity and sea level pressure and
style H and HS at 125°C have been tested to
make and break the following loads as stated
in MIL-S-3786/SR04; 250 milliamperes at 28
Vdc resistive, 100 milliamperes at 28 Vdc
inductive (2.8 henries); 75 milliamperes at
115 Vac resistive.
These switches have also been tested at
reduced barometric pressure (70,000 feet),
25°C at approximately 68% relative humidity
to make and break the following loads as
stated in MIL-S-3786/SR04; 200 milliamperes,
28 Vdc resistive; 25 milliamperes, 28 Vdc
inductive (2.8 henries); 20 milliamperes, 115
Vac resistive. When tested to these loads
and conditions the style M, H and HS switches
meet the following life limiting or failure criteria
after 25,000 cycles in accordance with MIL-
S-3786.
Contact Resistance: 50 milliohms maximum
Insulation Resistance: 1,000 megaohms
minimum between terminals and shafts
Dielectric Strength: 1,000 Vac (atmospheric
pressure) and 450 Vac (reduced pressure)
minimum between mutually insulated parts.
When tested at sea level 25°C and 68%
relative humidity with failure criteria of 50
milliohms max. and 750 Vac breakdown
voltage, these switches will make and break
the following loads: 250 mA at 28 Vdc,
inductive (2.8 henries); 1.25 amps at 28 Vdc
resistive; 2.0 amps at 115 Vac, 60 Hz resistive,
for 10,000 cycles.
These switches also meet MIL-S-3786/SR04
for moisture resistance, medium and high
shock, vibration (10 to 2000 cps), thermal
shock (-65°C to 125°C), salt spray, explosion
and terminal pull.
