The HTTM Capacitive Touch Switch Button Module series features the following characteristics:

• It has no mechanical parts, does not wear out, has infinite lifespan, reducing maintenance costs.
• The sensor unit can be placed behind any insulating material (usually glass or plastic), making it easy to seal the keypad surface with its environment to provide protection from moisture and water.
• Panel design as desired, key size and any shape, character, brand, or window design, offering a more vivid feel to the product.
• Compared to physical buttons, touch buttons are more difficult to damage.
• You can modify the resistance on the back side, and the output signal setting can be momentary or maintain the output level.
• Very wide input voltage range from +2.7V to +6V, the +3.3V signal output can be used directly to drive relays, optocouplers, LED lights, and more.
• Operating temperature range from -30 to +70 degrees Celsius.
• Touch sensitive, with no delay or other negative reactions.
• Built-in anti-interference algorithm with excellent anti-interference performance.
