25mm Capacitive Switch

The new CP Series capacitive touch switch technology senses the touch of a finger and creates an electrical charge to activate the switch. An auto-calibration function ensures the sensor adapts to changing external environments.
LANGIR's capacitive touch switches are specially designed for durability and a low activation force. As sensitive as a touch screen, the capacitive switches are perfect for industrial applications where repetitive activation can cause operator fatigue.

FAQs

Q1: What is a capacitive touch switch?

A: A capacitive touch switch is an electronic device that detects touch input through a touch-sensitive surface using changes in capacitance. It allows users to control functions or operations by simply touching the surface.

Q2: How does a capacitive touch switch work?

A: Capacitive touch switches work by creating an electric field on a touch-sensitive surface using electrodes. When a conductive object, like a finger, comes into proximity or makes contact, it disrupts the electric field, changing the capacitance. This change is detected, and the switch triggers a specific action.

Q3: Do capacitive switches require a power source?

A: Yes, capacitive switches typically require a power source to operate. They are connected to a power supply to function correctly.

Q4: Are capacitive touch switches suitable for people with disabilities?

A: Capacitive touch switches can be a viable option for individuals with disabilities. Their touch-sensitive nature requires minimal force to activate, making them accessible for individuals with limited dexterity or mobility. However, it’s important to ensure that the switches are properly calibrated and positioned to accommodate the specific needs of each user.

Q5: Do capacitive switches consume a lot of power?

A: Capacitive switches have low power consumption compared to other types of switches. The power usage primarily occurs when the switch detects touch input and triggers an action. During idle or standby modes, the power consumption is minimal.

Q6: Can capacitive switches be integrated into smart home systems?

A: Yes, capacitive switches can be integrated into smart home systems. They can be connected to a central control unit or home automation hub to enable remote operation and integration with other smart devices. Consult the manufacturer’s specifications and compatibility guidelines for seamless integration.
