Precision activation for arming, fuzing, and event sequencing
This collection groups inertial switches, impact/crush, disturbance/vibration, and acceleration (G-switches) engineered for MIL-SPEC environments, meeting ISO 9001:2015 and AS9100 quality expectations. These munitions switches are built for in-flight event sequencing, impact detonation logic, and safety interlocks with G-force sensing calibrated to specific operational requirements. Applications range from missile arming systems requiring precise activation thresholds to loitering munitions demanding reliable disturbance detection across extreme operational conditions.
Category Overview
Safe, repeatable switching for mission-critical munitions defines this specialized collection of switches designed for munitions arming, fuzing, and flight operations. Our munitions switches encompass inertial switch munitions, impact/crush devices, disturbance/vibration sensors, and acceleration (G-switches) that meet the demanding safety and redundancy requirements outlined in MIL-STD-1316E for fuze design.
These switches deliver tested reliability to MIL-STD-810 specifications for shock and vibration environments, backed by traceable documentation that supports audit requirements and program qualification. Hermetically sealed G-switches sense launch acceleration with precision. Latching crush switches provide reliable impact detonation logic. These components deliver the environmental sensing and safety interlocks that procurement teams depend on for mission-critical programs.
Explore Sub-Collections
Select Controls' munitions switch technologies align with mission-critical use cases across arming and fuzing chains, impact detonation triggers, and disturbance sensing for flight or storage applications. Each product line delivers the safety interlocks, environmental resilience, and complete program documentation (COC, FAIR, and lot traceability) that defense programs require for qualification and deployment.
These capabilities are organized across five specialized product families:
Acceleration Switches
Inertial switch munitions and acceleration sensors for safe-arm devices and velocity-threshold arming sequences. These designs are commonly deployed as munitions safety switch elements within safe-arm mechanisms where G-force sensing governs arming authorization.
Impact Switches
High-G detonation triggers with activation thresholds from 0.5g to 625g for point-detonating fuzes.
Disturbance Switches
Motion sensors for tampering detection and flight-path monitoring with configurable sensitivity.
Crush Switches
Latching impact switches for munitions safe-arm devices requiring maintained closure after activation.

Frequently Asked Questions
Munitions switch selection depends on your specific application requirements. Acceleration switches handle velocity-based arming and launch detection. Crush switches provide impact detonation triggers with latching behavior. Disturbance switches detect vibration or motion for safety interlocks.
Our munitions switch designs are qualified to MIL-STD-810 environmental testing requirements for shock, vibration, and temperature cycling. Each product line includes hermetic sealing, gold-plated contacts, and materials selected for defense applications with documented test compliance.
Every shipment includes Certificate of Compliance for MIL-SPEC requirements, material traceability records, and test reports. ISO 9001:2015 certification provides lot tracking and quality documentation that meets audit requirements for defense procurement and program management oversight.
Standard production runs 4-6 weeks for catalog items, with expedited 2-week options available. Custom munitions switch designs require 6-8 weeks including prototyping. Select Controls' proven rapid prototyping capabilities support urgent program needs with priority scheduling and dedicated engineering support.
Trusted by Programs That Count
Engineers who work with our switches give us high marks for good reason. When your program depends on switches that work every time, you need a supplier with a track record you can verify.
Testing You Can Document
Our acceleration switches go through a series different quality checks during manufacturing - everything from material inspection to final testing. We're ISO 9001:2015 certified, which means our processes are audited and verified by third parties. Every switch comes with full traceability records showing exactly how it was made and tested.
Documentation and Support That Works
Every order includes certificates of conformance and detailed test reports. Need help with design reviews or qualification requirements? Our engineering team responds quickly and provides the technical support you need to integrate our switches into your systems.
