Power Rating

The power rating defines the maximum electrical load an ESP32 power switch can safely control. Exceeding this limit can lead to component failure, overheating, or even fire hazards. It's crucial to match the switch’s power handling capacity—measured in watts (W) or amperes (A)—to the connected load.

• For resistive loads (e.g., heaters), ensure the switch can handle peak current draw
• For inductive loads (e.g., motors, solenoids), derate by 20–30% due to surge currents
• Always include a safety margin (10–20%) above the expected load
• Check whether the rating applies to AC or DC loads, as some switches are optimized for one

Key tip: Use a multimeter or clamp meter to verify actual load before finalizing switch selection.

Voltage Compatibility

ESP32 microcontrollers operate at 3.3V logic levels, so the power switch must be compatible with this control voltage. However, the load-side voltage may vary significantly (e.g., 5V, 12V, 24V, or 120/240V AC).

• Ensure the control input accepts 3.3V TTL signals from the ESP32 GPIO pins
• Verify the switch can handle the load-side voltage (DC or AC) without arcing or breakdown
• Some modules include built-in level shifters for 5V-tolerant inputs
• Avoid direct high-voltage switching unless using isolated relays or SSRs

Critical note: Mismatched voltage can damage the ESP32 or cause erratic behavior.

Heat Dissipation

Power switches—especially MOSFETs and solid-state relays—generate heat during operation. Inadequate thermal management can lead to premature failure or thermal shutdown.

• High-current switches (>5A) should have integrated heatsinks or be mounted on metal surfaces
• Consider ambient temperature and enclosure ventilation in your design
• Use thermal paste or pads for better heat transfer when applicable
• Monitor temperature during prolonged operation using IR thermometers or thermal sensors

Best practice: Operate switches below 80% of their rated capacity to reduce thermal stress.

Electrical Isolation

Isolation separates the low-voltage control circuit (ESP32) from the high-voltage load circuit, enhancing safety and reducing noise interference.

• Opto-isolated relays use light signals to trigger switching, preventing voltage spikes from reaching the ESP32
• Isolation ratings (e.g., 2500V RMS) indicate safety margins for high-voltage applications
• Galvanic isolation prevents ground loops and improves system stability
• Essential for industrial, outdoor, or mains-powered systems

Safety first: Always use isolated switches when dealing with AC mains or high-energy circuits.

Regular Inspection

Like all electronic components, ESP32 power switches benefit from routine checks to ensure continued reliability.
