Abstract
A press button type safety switch is constructed to include a switching mechanism for switching the circuit between on/off positions, a spring-supported press button, a push member pivoted to the spring-supported press button and controlled by the spring-supported press button to slide along two symmetrical sliding tracks and to switch the switching mechanism between on/off positions, and a retaining structure provided between the switching mechanism and the push member and adapted to hold the press button in “on” position when the switch switched on and to release the press button when the switching mechanism tripped off upon an overcurrent.
