C152 switch panel

The 152's lower panel, its long strip folded into two rows: the CARB HEAT knob, the PRIMER, the red split MASTER rocker, the key and the lighter on top; the DOME LT, PITOT HT and LIGHTS rockers below. Each switch sets the simulator's and shows where the simulator has it.

Modeled on: Cessna 152 lower switch panel
Category: Airframe
Size: 2 × 1 cells

Plan: Pro
Simulators: MSFS 2020 · MSFS 2024 · X-Plane 11 · X-Plane 12

Features

CARB HEAT knob: pulled, the carburetor heat on; pushed home, off
Key with OFF, R, L, BOTH, START; START is held (re-sent every 0.3 s while held) and springs back to BOTH when let go
Red split MASTER rocker, ALT and BAT, interlocked as the real ones: ALT on takes BAT on, BAT off takes ALT off
Rockers in black bezels with white paddles, OFF / ON printed at the ends: DOME LT, PITOT HT, and the LIGHTS (NAV, STROBE, BCN, TAXI, LDG) in one bezel
No simulator counterpart: the PRIMER (pulled while held, then pushed home), the DOME LT rocker and the lighter (pushed in, it pops back out after a few seconds)
Each switch shows what you set at once, then follows the simulator
Click sound and haptic on every switch; the panel widens to fill its two cells and takes the red flood light at night

On the iPad

Touch the CARB HEAT knob to pull or push it, or drag it down to pull and up to push
Touch a key position, or drag the key round to it; hold at START to crank, release to spring back to BOTH
Tap the ALT or BAT half of MASTER to toggle it; swipe up for on, down for off
Tap a rocker (PITOT HT, NAV, STROBE, BCN, TAXI, LDG) to flip it; swipe up for on, down for off
Pull the PRIMER and let it go; push the lighter in

Simulator data

What the Hub reads from the simulator for this instrument, and what the instrument sends back. Names are the simulators' own: MSFS SimVars and events, X-Plane datarefs and commands.
