The KW11 Bump Sensor – Subminiature Micro Limit Switch is a compact mechanical switch designed for detecting physical contact, movement, and end-of-travel conditions in electronic and robotic projects. Its small size makes it suitable for applications where limited mounting space is available.
The switch operates through a mechanical actuator that changes the electrical contact state when pressed. It can be used as a bump sensor, limit switch, position detector, end-stop, or simple push-operated input in DIY electronics and automation systems.
The compact construction makes the KW11 suitable for small robots, particularly obstacle-detection and collision-detection mechanisms. It can also be mounted on moving mechanisms to detect when a component reaches a predefined position or mechanical limit.
This subminiature micro limit switch is useful for makers, students, hobbyists, and electronics developers. It can be connected to a microcontroller such as Arduino, Raspberry Pi, or other control systems using a suitable pull-up or pull-down configuration according to the project requirements.
