Mechanical Ratings

Mechanical Life: 4,000 cycles maximum. Note:

a cycle is one complete operation, back and

forth through all switch positions.

Vibration Resistance: 10 to 2,000 Hz at 15G

or 0.060" double amplitude, per MIL-STD-202F

per MIL-5-83504; Method 213, Condition A. No

damage and no contact openings exceeding

10 mS (Method 204, Test Condition B).

Shock Resistance: 509, 11 mS, half sine; no

damage and no openings exceeding 10 mS

(Method 213, Test Condition A).

Environmental Rating

Operating Temperature Range: -40°C to

+85°C

Storage Temperature Range: -55°C to +85°C

Moisture Resistance: 240 hours with

temperature cycling and polarization, per MIL-

STD-202F, Method 305

Circuit Selector

Isolated Circuits in 10 and 16 Positions

Each position is a single isolated circuit, which

connects the two terminals across the switch

package. The movable contact is non-shorting.

Tap Switch

SP/10 Positions, and SP/16 Postions

All contacts on one side of the switch are internally

bussed for a common pole. Any terminal on that

side may be used as a common, the others may

be clipped. The movable contact is non-shorting.
