The circuits were designed to illustrate the functions of two switches with the use of a single op-amp to show the operations of a precision light sensitive switch and a differential switch. LM741 – a ...

It sounds rather mysterious: a switch that is controlled by its ambient temperature. All without the touch of a human hand, except for when you’re building this sort of electronic thermostat. There ...

Liquid-level switches used in aircraft, nuclear-power plants, medical equipment, and other critical applications must be precise and reliable. For that to happen, design engineers must know the ...
