Abstract
An electrical switch for providing power from a power source to a component may include a voltage supervisor having an input and an output, a voltage divider, electrically coupled between the input of the voltage supervisor and ground, an RC filter electrically coupled to the output of the voltage supervisor, and a field-effect transistor having a first terminal coupled to the RC filter and a second terminal coupled to an output of the switch, the output configured to be electrically coupled to the component. A switch may additionally or alternatively include a light source electrically that emits light when power is provided from the input of the switch to the component, the light source arranged proximate a fuse so as to illuminate the fuse.

An electrical switch for providing power from a power source to a component, the switch comprising:
- a voltage supervisor having an input and an output;
- a voltage divider, electrically coupled between the input of the voltage supervisor and ground;
- an RC filter electrically coupled to the output of the voltage supervisor;
- a field-effect transistor having a first terminal coupled to the RC filter and a second terminal coupled to an output of the switch, the output configured to be electrically coupled to the component;
- a fuse;
- and
- a light source arranged proximate the fuse so as to illuminate the fuse when provided with power from the power source, wherein the light source is electrically coupled to the output.
