Shop the Impact-Activation Models
Munitions across all platforms require precision-engineered switches that perform reliably throughout the operational lifecycle—from safe storage and transport through launch dynamics to terminal impact activation. Our impact-activation models address each phase with switches built for specific mechanical loads, environmental conditions, and safety requirements.
Our specialized models include:
Crush Switches
Engineered for high-force impact scenarios where deformation triggers activation. Ideal for artillery shells, mortar rounds, and direct-attack munitions requiring dependable terminal activation.
Mechanical Detonation Switches
Spring-loaded mechanisms that activate under precise impact thresholds. Commonly specified for munitions, loitering systems, and applications where electronic sensors may face interference.
Impact Sensors for Explosive Ordnance
Multi-directional impact detection systems built for complex munition platforms. These sensors support UAS payloads and advanced ordnance requiring selective activation modes.
Acceleration-Based Switches
Launch-activated switches that respond to specific G-force profiles during firing or deployment. Standard in safe-arm devices, artillery fuzing, and rocket-propelled systems.
Each model includes documented test data, compliance certifications, and rapid prototyping support to accelerate your qualification timeline from initial specification through production delivery.
Frequently Asked Questions
Mechanical detonation switches use purely physical mechanisms—springs, masses, and contacts—to activate upon impact. Electronic sensors require power and processing circuits. Mechanical switches offer simpler integration, higher reliability in extreme environments, and immunity to electromagnetic interference.
A crush switch for detonation works best when space constraints demand compact form factors or when omnidirectional impact sensitivity is required. These switches activate under compressive forces from any angle, making them ideal for warheads requiring reliable detonation regardless of impact orientation.
MIL-STD-331 covers environmental testing for vibration, shock, and temperature extremes. ISO 9001:2015 certification ensures quality management systems. Additional standards include MIL-STD-1316, for fuzing components for electromagnetic compatibility in ordnance systems.
Impact-based activation systems incorporate safety interlocks and arming logic that prevent accidental activation during handling. These sensors remain inert until specific acceleration thresholds are met, providing multiple layers of protection while maintaining reliable performance when deployment conditions are satisfied.
