Explore Sub-Collections

Safe and arm devices serve distinct functions across mission profiles, organized by activation axis (single, dual, or omnidirectional), g-threshold ranges (1.5g to 15000g's), and environmental ratings including temperature extremes and shock resistance. These collections enable direct comparison of switching mechanisms, environmental survivability, and integration requirements.

Setback Activation Devices

Launch-initiated arming mechanisms that respond to acceleration forces during projectile firing. Mechanical and electro mechanical safe and arm device options with configurable thresholds from 1.5g to 15000g's, operational from -65°F to +200°F with MIL-STD-810 shock resistance.

G-Switch Fuzing Assemblies

Precision G-switch for fuzing applications requiring target impact detection and detonation timing. MIL-SPEC compliant assemblies tested for 15,000g shock survival with hermetically sealed contacts for harsh environments.

Acceleration Switches

Frequently Asked Questions

Electro-mechanical devices combine mechanical setback sensing with electrical switching circuits, providing redundant safety verification. Mechanical devices rely solely on physical mechanisms like spring-loaded pins or rotating masses for arming sequences, offering simpler integration but fewer monitoring capabilities. Mechanical devices do not draw any current when not operating, extending battery life.

Setback devices prevent premature arming by requiring specific acceleration profiles during launch or deployment. They physically block firing circuits until predetermined g-force thresholds are met, providing fail-safe protection against accidental activation during handling, transport, or storage.

G-switches provide precise acceleration threshold detection for reliable fuzing sequences. They meet stringent MIL-SPEC requirements for environmental survivability, ensuring consistent performance across temperature extremes, vibration, and shock conditions while maintaining calibrated sensitivity for mission-specific activation profiles.

Consider activation thresholds (2g to 5000g options), environmental ratings per MIL-STD-331, mounting orientation, and electrical interface requirements. Match switch sensitivity to your specific launch profile while ensuring adequate safety margins for reliable operation across expected mission conditions.
