Using fuses as power switches on camera sleds versus removing batteries or disconnecting cables
What the thread found
- Fuses can be used as switches to disconnect power from equipment on a sled instead of removing batteries or unplugging cables.
- Fuses have a limited number of mechanical cycles before they wear out, typically around 5000 switching operations.
- Repeatedly switching fuses as power controls will eventually degrade them and may require replacement.
- Pulling fuses while leaving other connections intact allows selective power management, such as keeping camera power on while disconnecting monitoring equipment.
Depends on
- The 5000 cycle lifespan figure is based on general component specifications and may vary by fuse model.
- One reported instance of a fuse breaking during use, but unclear whether this was due to repeated switching or physical damage.
- Discussion does not specify what type of camera sled or fuse design is being used.
