This timer can be used for ignition of sustainer motors in multistage rockets and
ignition of air-started auxiliary motors. It can also be used for accurately timed
deployment of recovery devices in lieu of the sometimes variable delay times associated
with the motor's built-in delay grain. Delay time can be set with 0.1 second resolution
via an on-board pushbutton.
The miniTimer3T is designed to be triggered via a user-supplied breakwire or pull-pin
(the MT3G version includes a built-in G switch trigger). Igniter continuity is reported
via a built-in beeper, which doubles as a post-flight locator siren.
The miniTimer3’s extremely high current capability allows the use of virtually any
igniter type, as well as multi-igniter clusters. When powered by a suitable battery,
firing 50 ematches simultaneously is possible!
