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 ...

A boiler water temperature controller is just an on and off switch that controls water temperature. How simple can you get! It's like a thermostat, but for water instead of air. Yet the terminology ...

The devices’ temperature-switch threshold is programmable with a single external resistor, which means that designers can stock one device for measuring multiple temperature points by varying the ...
