Added 1x SPDT Toggle Switch on-none-on as SW1 (Pins: 1, 3, 2)

Added 1x NE555P - 518340 as U1 (Pins: R, GND, DIS, THR, Q, CV, TR, VCC)

Added 3x Generic Resistor as R1, R2, R3 (Pins: P2, P1)

Added 4x Generic Capacitor as C1, C2, C3, C4 (Pins: P1, P2)

Added 1x LTL-307EE as LED1 (Pins: K, A)

Removed U1

Removed J1

⚠️ Removed components had their net connections destroyed. Use the connections tool with a `view` action to verify connectivity and re-wire any lost connections.
