The HS-S43P is a capacitive touch button module compatible with 3.3V and 5V logic systems like Arduino, Raspberry Pi, and ESP32. It provides a reliable, non-mechanical touch interface via a gold-plated contact pad.

Features

  • Capacitive sensing via gold-plated contact pad for high sensitivity.
  • Switchable between latching switch and momentary button modes via solder Jumper.
  • Operates on 3.3V or 5V DC power supply with PH2.0 interface for easy connection.
  • Detects touch through non-conductive materials like plastic or glass.
  • Compact PCB with dual mounting holes for secure installation.

Description

The HS-S43P touch button module operates on the principle of capacitive sensing, detecting changes in capacitance when a conductive object (like a human finger) approaches or contacts its gold-plated pad. This allows for touch detection not only through direct contact but also through insulating overlays of a defined thickness.

The module features a configurable output mode, selectable by soldering a Jumper connection. In ‘switch’ mode, the output toggles with each touch, ideal for applications like touch-controlled lamps. In ‘button’ mode, it provides a momentary high signal while touched, suitable for replacing physical pushbuttons. Proper installation with an air gap between the module and the mounting surface is required to prevent false triggering.

Key Features

  • High-sensitivity capacitive touch detection with gold-plated contact surface.
  • Dual-mode operation (latching switch or momentary button) via solderable Jumper.
  • Wide operating voltage range of 3.3V to 5V DC for broad microcontroller compatibility.
  • PH2.0 connector interface simplifies wiring and prototyping.
  • Compact, durable PCB construction with screw mounting holes for stable integration.
  • Capable of sensing touch through non-metallic covers like plastic or glass.
  • Optimized performance-to-cost ratio for replacing mechanical switches.

Applications

  • Replacement for mechanical buttons in consumer electronics and control panels.
  • Touch-activated controls for desk lamps, IoT appliances, and smart home interfaces.
  • User input interfaces for Arduino, Raspberry Pi, or ESP32-based projects requiring sealed controls.
  • Industrial HMI panels where a durable, sealed touch interface is needed.
  • Interactive exhibits or displays with touch sensing through a protective glass or acrylic layer.

Frequently Asked Questions

What is the operating voltage range for the HS-S43P touch button?

The HS-S43P module is designed to operate on a DC supply voltage of either 3.3V or 5V, making it directly compatible with most common microcontroller platforms like Arduino, ESP32, and Raspberry Pi (using 3.3V logic). Ensure your power source provides a stable voltage within this range.

How do I switch between the switch mode and button mode?

The output mode is configured by soldering a Jumper connection on the module's PCB. Soldering the two upper short-circuit points sets the module to 'switch' (toggle/latching) mode. Soldering the two lower short-circuit points sets it to 'button' (momentary) mode. Only one pair should be soldered at a time.

Can this sensor detect touch through a cover?

Yes, the capacitive sensing principle allows the HS-S43P to detect touch through non-conductive materials like plastic, glass, or acrylic, provided the overlay is not excessively thick. Sensitivity decreases with increased material thickness, so testing with your specific cover material is recommended.

What is the correct way to mount the HS-S43P module?

Mount the module using the two provided screw holes to secure it to your enclosure. It is critical to maintain a small air gap between the back of the PCB and the mounting surface to prevent parasitic capacitance from causing false triggers. Avoid direct handling of the touch pad during operation to prevent overheating.

What type of connector does the module use?

The module features a standard PH2.0 pitch connector for power and signal output. This common connector type allows for easy wiring with pre-made Jumper cables, simplifying integration into breadboards or connection to microcontroller GPIO pins.
