Transistor Symbols

The Transistor is a device semiconductor provided with three terminals called base, issuer and collector. It is used to work in electronic circuits as rectifier, amplifier, switch...
These symbols can be represented inside a circle.

Symbols of Electronic Sensors, Transducers, Detectors...

The transducers, sensors and electrical and electronic detectors are elements that are activated by the energy delivered by a system and that in turn deliver another type of energy to another different system. The transformed energy may be physical, chemical or biological origin.
