With the detent pin installed in the breaker switch, the electrical system is grounded in the safe position, and the rockets won’t fire. The detent pin has a REMOVE BEFORE FLIGHT red streamer attached. Pull the pin immediately before the aircraft takes off and install it immediately after the aircraft lands. Install the detent pin in the breaker switch before loading the launcher with rocket motors. Keep the detent pin installed, except during actual flight, until the launcher is downloaded and/or verified as being empty. Mode Selector Switch The mode selector switch (figs. 2-29, 2-30, and 2-31) is used on all launchers. The switch is located in the aft bulkhead of the launcher. The switch permits preflight selection of either ripple or single firing of the rockets by controlling the functioning of the pod intervalometer. Intervalometer The intervalometer for the LAU-10 (series) pods is located in the forward bulkhead of the center section (fig. 2-29) and in the aft bulkhead for the LAU-61 and LAU-68 (series) (figs. 2-30 and 2.-31). Intervalometers, whether installed in 5.0-inch or 2.75-inch launchers, perform the same function. If the mode selector switch is in the SINGLE fire position, the intervalometer fires one rocket on each Figure 2-31.—Mode selector switch and intervalometer (LAU-61A/A, LAU-61B/A, and LAU-61C/A). 2-27
