A mountable housing for a SS-5GL mini microswitch - commonly used in AV bays of high power rockets.
2mm rod used to keep switch open.
Solder +ve lead of battery to the 2 outside lugs - CO and NC to ensure circuit is broken when pin is inserted.
STP file also included to enable file to be incorporated in to modular AV bay designs - see my design for all in one nose sled.
The author marked this model as their own original creation.
