The invention provides an electric starting switch, comprising a button switch assembly, wherein a starting button is arranged at the outer end of an assembly button; a compression spring is fixed on the starting button; in a process that the starting button compresses the assembly button until the starting button resists the assembly button and inwards compresses the assembly button to an inner limiting position, a moving contact and a fixed contact in the button switch assembly are switched on, and then the compression spring is compressed to a state that each circle of spring wire is compressed mutually. An iron core is arranged between the assembly button and the starting button, and when the compression spring is compressed to the state that each circle of spring wire is compressed mutually, the periphery of the iron core is surrounded by the compression spring. A first wiring terminal of the button switch assembly is connected with the compression spring and then is electrically connected with the moving contact of the button switch assembly, and a second wiring terminal is directly electrically connected with the fixed contact of the button switch assembly. A according to the electric starting switch, a relatively high starting voltage can be provided at the moment when the electric starting switch is switched on.
