Switch Type: The basic snap action switches are qualified to MIL-PRF-8805/101 category I or category II.
Switch Capacity: Single pole double throw, double pole double throw or four pole double throw.
Switch Contact Schematic: The switch contact arrangements are either single break or double break. The double break allows two separate contact circuits or simply a
single throw contact action. See Figure 5.

SWITCH CIRCUIT SCHEMATIC
Switch Contact Resistance: 0.025 ohms maximum.
Intermediate Current: The intermediate current test per MIL-PRF-22885 paragraph 3.35 is applicable to the gold flash silver contacts. 50,000 cycles minimum, 12,500 cycles at -55°C, 25,000 cycles at +23°C and 12,500 cycles at +85°C.
Low Level Life: The low level life test per MIL-PRF-22885 paragraph 3.36 is applicable to the gold plated contacts. 50,000 cycles with contacts loaded at 30 millivolts maximum DC or peak AC at 10 milliamperes maximum. 12,500 cycles at -55°C, 12,500 cycles at +23°C and 25,000 cycles at +85°C.
Dielectric Withstanding Voltage:
At sea level: 1000 volts rms minimum, 60 Hz.
At 50,000 ft.: 400 volts rms minimum, 60 Hz.
Lamp Circuit Schematic: The lamp circuit is available with a common ground,
horizontal split ground or vertical split ground. See Figure 6.

LAMP CIRCUIT SCHEMATIC
Terminals: Both the switch circuit and the lamp circuit terminals are gold plated brass.
Switch and Terminal Identification: The switch poles are denoted as position A and B. Switch terminals are marked 1, 2, 3 and 4. The lamp terminals are marked A, B, C, D, F
and G. See Figure 7 for exact terminal identification.

Low Power Lamps: Four low power T-1 size flange-based lamps are supplied with each pushbutton switch.
Three lamp types are available:

Low Touch Temperature: Heat dissipation properties designed into the pushbutton caps combined with the use of low power lamps results in low touch temperature. The 5 volt, 0.060 amp lamp (P/N 17-043) produces a touch temperature of 43°C with two lamps on and 49°C with four lamps energized. The 5 volt, 0.115 amp lamp (P/N 03-014) produces a touch temperature of 49°C with two lamps on and 65°C with four lamps energized. The 28 volt, 0.024 amp lamp (P/N 14-104) produces a touch temperature of 52°C with two lamps on and 74°C with four lamps energized.
EMI/RFI Shielding Option: When specified, the shielding efficiency of the pushbutton switch is no less than 60db for frequencies from 100MHz to 1000MHz.

ELECTRICAL FEATURES:
Unless otherwise stated, all the electrical features incorporated in Type I and III configurations (unsealed) have been incorporated in Type V configurations (see Data Sheet 95-1-86-3).
Switch Capacity: 4-pole double throw.
Switch Contact Schematic: The switch contact arrangements are either single break or double break. The double break allows two separate contact circuits or simply a single throw contact action. See Figure 34.
