Triac Schaltung. Triac working triac is a three terminal ac switch which can be triggered by a low energy signal at its gate terminal. For both positive and negative gate currents traic conducts but with only direction on gate current turn on the scr.
Triac circuits can be very straightforward requiring only a few components and they are able to provide a good degree of control and switching although they tend not to be used for high power levels where two discrete back to back thyristors provide better performance. Dabei wird die ein bzw. Am ton soll hörbar sein wie hoch der widerstand ist.
The triac structure is shown below and it can be seen that there are several areas of n type and p type material that form what is effectively a pair of back to back thyristors.

Ausgangsspannung hart kurzgeschlossen die sicherung ausgelöst und damit eine schaltung vor zu hoher oder falscher betriebsspannung geschützt. A triac is another 4 layer 3 terminal thyristor device similar to the scr.
