Abstract
A press button type safety switch is constructed to include a switching mechanism, a seesaw plank controlled by a press button assembly to switch on/off the switching mechanism, two spring members supporting the press button assembly in the upper limit (off) position, two locating rods horizontally aligned at two sides of the press button assembly, and two hooks upwardly extended from the seesaw plank and adapted to hook the locating rods of the press button assembly and to hold the press button assembly in a lower position spaced below the upper limit (off) position when the switching mechanism switched on, the hooks being disengaged from the press button assembly for enabling the press button assembly to be moved upwards to the upper limit position when the switching mechanism switched off or the safety switch automatically tripped off upon an overcurrent.
