G-Switches, Acceleration Switches, and Impact Switches for Aerospace and Defense Applications
High-reliability G-switches and acceleration switches engineered for fail-safe arming, detonation sequencing, impact sensing, and high-G event detection. Trusted across missile systems, munitions, ejection seats, UAVs, and aerospace safety systems.
Aerodyne Controls G-switches deliver instantaneous, passive activation and survive up to 30,000 Gs, providing dependable performance in environments where electronics cannot.
Engineering Risks of Improper Switch Selection
Without effective equipment in place, like safe and arm devices, acceleration switches, G-switches, and other key components, aerospace and defense organizations risk:
❌ Catastrophic field failures – Switch failures in munitions, missile systems, and ejection seats that can lead to injury or loss of life
❌ Compromised viability – Reduced switch viability in environments featuring extreme shock, vibration, and temperature fluctuations
❌ Spec misalignment – Switches that don’t meet predetermined needs for size, weight, and power while maintaining durability
❌ G-force issues – Switches that can’t handle extreme G-forces
In aerospace and defense, a single switch failure can cascade into mission loss or worse. Component selection is not the place to compromise.
Aerodyne Controls Is the Solution
Effective switches offer instantaneous, passive activation that uses calibrated spring-mass mechanisms that adhere to Hooke’s Law.
If you need a fail-safe, power-free alternative, trust in our G-switches. Performance provided, kinetically.
Plus, they come in unidirectional, multidirectional, and hemispherical acceleration switch variations that are hermetically sealed. And their passive design ensures precision and consistent activation thresholds during operation.
Our switches are purpose-built, high-volume kinetic devices that respond to acceleration, shock, impact, recoil, and spin, and we supply them for:
✅ Missile and munition impact detonation triggering
✅ High-G weapons release and arming systems
✅ Ejection seat sequencing
✅ Rocket motor ignition interlocks
✅ UAV safety systems
No matter your application, our engineers can tailor G-switches to meet the environmental and durability needs you require.

FAQs on Impact Switches, Safe and Arm Devices, and More
Do your switches require an external power source to trigger?
No, our impact and acceleration switches operate passively by using calibrated spring-mass mechanisms governed by Hooke’s Law, meaning that they require no electrical power to activate.
Can switches from Aerodyne Controls be customized for extreme environments or highly restricted spaces?
Yes, our team offers ultra-miniature micro switches (under 0.1 x 0.1 x 0.05 inches) and we can custom engineer switches with sensitivities ranging from 0.2 to 30,000 Gs to survive environments with severe shock, vibration, and temperature fluctuations.
Are your kinetic switches fully qualified for military and space applications?
Absolutely. We conduct comprehensive in-house environmental and performance testing to ensure complete compliance with MIL-STD, NASA, ESA, FAA, and specific customer requirements.
