When designing a steering switch control circuit, the following key considerations must be taken into account:
1. Reliability: The control circuit must be able to operate stably under various environmental conditions to ensure accurate transmission of the steering signal.
2. Safety: The circuit design should include necessary protective measures, such as overload protection and short-circuit protection, to prevent safety issues caused by circuit failures.
3. Ease of Use: The control circuit design should be simple and clear, allowing the driver to operate it quickly and accurately.
