It uses a stainless steel body with a blue illuminated LED ring for a polished, easy-to-see finish.The switch has latching operation, so it changes state ...
Gravity LED Switch Module - White
·
This compact illuminated push-button module combines a tactile switch with a built-in white LED indicator, making it handy for interactive electronics, prototypes and embedded control panels.The switch outputs a digital HIGH/LOW signal and runs from +3.3-5V, so it suits common development boards ...
Gravity LED Self-Locking Switch - Red
·
This illuminated pushbutton module is a simple self-locking switch with a built-in red LED for clear visual feedback. Press it once and the module outputs High while the LED turns on; press it again and the output goes Low while the LED turns off.It is designed for easy use in Arduino, micro:bit ...
Qwiic Power Switch
·
This compact Qwiic board lets you switch power to downstream Qwiic devices so high-current modules can be turned off when they are not needed. That can help conserve energy in battery-powered builds using GNSS and other power-hungry Qwiic boards.It also provides I2C bus isolation, so slower 100kH...
DFRobot Diffuse Reflection Photoelectric Switch 0-7m
·
