Retorgrade Rocket Squib Arm-Safe Switches

Retro Rocket Squib 1,2,3,4 Arm-Safe Switches

The four retrograde rocket squib arm switches apply the voltages which ignite the four retrofire rockets to open contacts of the retro rocket automatic and manual fire relays. In the safe position of these four switches, the ignition voltage is removed from the relays. When both the RETRO POWER squib arm switch and the four RETRO ROCKET SQUIB arm switches ere placed to the ARM position, the OAMS squib buses 1 and 2 are connected redundantly to the retrorocket fire relays.
