Perhatikan gambar skema rangkaian SCR dan kondisi rangkaian, berikut :
1. Sumber tegangan sudah di-ON-kan, namun LED (load) tidak menyala
2. Ketika hanya push button S2 ditekan terlebih dahulu, LED menyala, tapi hanya saat push button S2 ditekan.
3. Kemudian, jika hanya push button S1 ditekan, LED menyala terus, walaupun push button S1 tidak ditekan lagi.
Hal ini dapat disimpulkan bahwa prinsip kerja SCR, yaitu...
Ketika kaki Anoda pada SCR mengalir arus untuk sesaat (diberi trigger), maka SCR akan aktif terus.
Ketika kaki Gate pada SCR mengalir arus untuk sesaat (diberi trigger), maka SCR akan aktif terus.
Ketika kaki anoda dan katoda pada SCR mengalir arus untuk sesaat (diberi trigger), maka SCR akan aktif terus.
Ketika kaki gate pada SCR mengalir arus untuk sesaat (diberi trigger), maka SCR tidak akan aktif.
