ABSTRACT:
The switch has a housing adapted to receive a lever shiftable relative thereto between an ON position and an OFF position for activating an electric lawn mower. An activator button is movably affixed to the housing, such that the activator button is movable in a first degree of freedom relative to the housing between an ACTIVE position and a STOP position. The activator button is also movable in a second degree of freedom relative the housing between a READY orientation and a RUN orientation in response to movement of the lever to the ON position. A biasing means cooperates with the housing and the activator button for biasing the activator button toward the STOP position and the READY orientation. A normally open electrical switch is affixed on the housing for starting the electric mower. The electrical switch is closeable only when the activator button is moved to the RUN orientation. A detent cooperates with the housing and the activator button when the activator button is in the RUN orientation to prevent the biasing means from biasing the activator button to the STOP position.
