The Silicon Controlled Switch (SCS) is a power semiconductor device similar to an SCR, but it is designed to turn off when a positive voltage/input current pulse is applied to an additional "Anode gate" terminal.
The SCS can also be triggered into conduction mode by applying a negative voltage/output current pulse to the same lead.
In addition to this, the Silicon Controlled Switch behaves just like an SCR (ie, by applying positive voltage to the "gate" terminal we can turn on the device).
In summary, SCS is a four layer, four terminal PNPN semiconductor device. The four terminals are Anode (A) , Cathode (K) and two gates. The two gate terminals are namely anode gate (AG) and cathode gate (KG). The device has one anode gate (AG) similar to PUT and another cathode gate (KG) similar to SCR. As it has four terminals, it is named as tetrode (four electrode thyristor).
