PHASE CONTROL THYRISTORS

 Thyristors are "normally-off" switches that can be triggered 
 "on" by a small current pulse into the gate electrode. Once
  turned on (or "triggered"), the component then stays in the
conducting state even when the gate on-signal is removed.
It only returns to the "off" (blocking) state if the current falls
below a certain minimum or if the direction of the current is
reversed.
