When a pushbutton 45c of the front cover 14 is depressed, the metal segment 45a contacts the contact pattern 45b to turn on. The trigger switch 35 is constituted by a pair of segments arranged vertically, and turned on when they... ...
Pololu Pushbutton Power Switch OFF input detail. The latching circuit controlling the power MOSFET includes an OFF input that can be used by the target device to shut off its own power. The internal structure of this input is shown to the right. Applying more than approximately 1 V to the...
A push-button is a momentary or non-latching switch that causes a temporary change in the state of an electrical circuit only while the switch is physically actuated. An automatic mechanism (such as a spring) returns the switch ...
