2020 SERIES

Inertia Switches

C

ole’s 2020 Series Inertia Switch provides the ultimate mechanical

and electrical reliability.

The 2020 Series is available with one pole and with variable

amplitude of 1 to 100 Gs, with turret or solder lug terminals, and with

normally open (N.O.) or normally closed (N.C.) contacts. They are

also resettable for testing purposes.

Cole’s inertia switch is designed for critical ordnance applications,

missile arming, wing deployment and detonation on impact.

Precision construction with the highest quality materials provides

high current capacity with constant low contact resistance and

exceedingly stringent inspection and testing procedures promise

extreme reliability.

ISO9001 CERTIFIED
