Hardware.

Carling toggle switches, with actuators of either the nylon paddle or steel bat. The switch guards protect
- switches that would affect engine spark
- switches that control the fuel pumps and
- the defeat of the autoextend module for the landing gear.

Battery Contactor / "Master". Battery contactors are the "master" switch, and I used the standard wiring - the panel switches the ground while power is a direct connection from the battery post. So long as the ground is connected the battery will flow 18 watts of power to the contactor. The electromagnet will stay in the raised position and the contactor will stay closed. The panel switch is off-1-both, where the #1 circuit completes the link to the battery ground. I used 16 AWG for the ground connection (a red & black twisted pair) at the switch - on an all electric airplane this is a peace-of-mind matter. The "both" position brings the alternator online by sending the field signal to the alternator. Note that another switch, described below, changes the power source to the backup alternator. Alternator field is a 3a circuit.

Start Contactor / "start button". Using electronic ignition I have a start button and a 1-2-both switch for coil packs. The starter load is intermittent, and that FAA chart allows for 20 AWG. I made a red (starter) & black (battery) twisted pair for the contactors, using 16 AWG - on an all electric airplane this is a peace-of-mind matter.
