Safety switch for a vehicle starting system
A safety switch is coupled to a control line of a vehicle starting system, and includes a first electrical connector that terminates a second branch of the control line, a first resistor that connects a first branch of the control line to a first voltage source, a switch element having a first end connected to a second voltage source, and a second end terminated by a second electrical connector that mates with the first electrical connector, and a second resistor connected in parallel with the switch element. The switch element makes or breaks electrical connection between the first and second ends according to a detected position state of an engine hood of the vehicle. The starting system is enabled so as to permit remote-controlled activation of the vehicle only when a voltage drop, the magnitude of which is between the voltage outputs of the first and second voltage sources, is present at the control line.
