12V 16mm Metal Panel Push-to-Stay On/Off Switch with Red LED

Description

Technical Description

The self-locking push button ON/OFF switch with red LED 12V 16MM metal panel is an electronic component used for manual control of 12V powered electrical devices. The self-locking button allows the switch to remain in the ON or OFF position once activated, until it is released again. The red LED indicates the activation status of the switch. This switch is designed to be mounted on panels or rigid surfaces and can be used in various electronic projects and applications.

For its use, the switch must be correctly connected to the power supply circuit of the device to be controlled and to a digital input pin of an Arduino or another control board. Make sure to check the electrical compatibility and proper protection of the digital pins with any resistors.

The switch is suitable for applications where direct and visible manual control of the activation state of an electrical device is necessary.
