This was successful because the LED turned on when I completed the circuit by flicking the switch.

The thyristor latched onto the current and continued the circuit when the power supply was cut.

When the SPST is closed, the LED will remain off until the push-to-make switch is pressed. The LED will then remain on until the power supply is isolated as the thyristor has latched onto the current.
