General Purpose 5VDC SPDT Non Latching Through Hole Power Relays ROHS SPDT SRD Series Form C

makes a circuit which has transistors, diodes, relays, IC Timer, LED, which first turns on a green LED lit from 0 to 35 degrees Celsius then turns off and turns on a yellow LED from 35 degrees Celsius to 50 degrees Celsius then turns off the yellow and turns on the red at 50 degrees or more which in turn will turn on an oscillator circuit with IC555 and a Buzzer. In addition it should turn on an exhaust fan at 110 VAC. Translated with DeepL.com (free version)

Push start button for a non immobiliser car. Push the button once sw1, and accessories come on, Push the button Once again sw1. and the ignition comes on. Hold your foot on the brake sw2 and the clutch sw3, Push the button sw1 and hold it down until the car starts. only releasing it after the car starts, Then press the button sw1 once to turn the vehicle off. using relays.
