3.7 Dropout voltage (see 6.4.1). When fail-safe electromechanically operated switches are tested as specified in
3.8 Operating current (see 6.4.10). When electromechanically operated switches are tested as specified in 4.7.6,

the lowest operating temperature shall not exceed the maximum specified value by more than 25 percent.
3.9 Holding current (see 6.4.3). When fail-safe electromechanically operated switches are tested as specified in
4.7.7, the holding current value shall not exceed the value specified (see 3.1). The measured holding current at the
lowest operating temperature shall not exceed the maximum specified value (see 3.1) by more than 25 percent.
3.10 Rotor motion delay (when specified) (see 6.4.7 and 3.1). When electromechanically operated switches are
tested as specified in 4.7.8, the rotor motion delay time shall not exceed the time specified (see 3.1).
3.11 Dielectric withstanding voltage. When electromechanically operated switches are tested as specified in 4.7.9,
there shall be no evidence of voltage breakdown.
3.12 Transient interference (RFI) (when specified) (see 3.1). When electromechanically operated switches are
tested as specified in 4.7.10, the switch shall not conduct or radiate RF noise to a degree greater than the following
limiting values:
DC switches +50 percent or -150 percent of nominal line voltage (28 V dc limit is ± 42 V peak).
a.
AC switches ± 2 x nominal RMS line voltage (115 V ac limit is ± 230 V peak).
b.
3.13 Isolation. When switches are tested as specified in 4.7.11, the isolation between the activated and any other
ports shall be not less than the value specified (see 3.1).
3.14 Voltage standing wave ratio (VSWR). When switches are tested as specified in 4.7.12, the input VSWR shall
not exceed the value specified (see 3.1).
3.15 Insertion loss. When switches are tested as specified in 4.7.13, the insertion loss shall not exceed the value
specified (see 3.1).
3.16 Switching time (see 6.4.8). When electromechanically operated switches are tested as specified in 4.7.14,
the time required to switch from one position to an adjacent position shall not exceed the time specified (see 3.1).
3.17 RF energy leakage (when specified) (see 3.1). When switches are tested as specified in 4.7.15, the RF
leakage shall not exceed the value specified (see 3.1).
3.18 RF power handling capability. When switches are tested as specified in 4.7.16, with specified RF power
(see 3.1) passing through the switch, no evidence of breakdown, charring, arcing, or overheating shall be evident.
Following this test, the switch shall be capable of meeting the specified insertion loss and isolation requirements.
Unless otherwise specified (see 3.1), switches shall not be required to switch under power.
3.19 Cycle life. When tested as specified in 4.7.17, the switch shall show no evidence of physical damage or
deterioration. Following the test, switching time, insertion loss, and VSWR shall be not greater than and isolation
shall be no less than the initial values specified (see 3.1).
3.20 Thermal shock. When electromechanically operated switches are tested as specified in 4.7.18, the switch
shall be capable of reliable operation. Following the test, the switch shall be capable of meeting the specified
insertion loss, isolation, and switching time requirements.
3.21 Altitude and cold. When electromechanically operated switches are tested as specified in 4.7.19, there shall
be no evidence of malfunction. Switches shall operate within the initial switching time specified (see 3.1) and
withstand dielectric withstanding voltage without breakdown (see 4.7.9).
