An explanation on how the circuit works is also included. This Push on off latching ... Yet Another self latching mosfet switch Page 1 A mechanical switch would mean to deface the meter and leave the APO signal not handled (the meter's own APO will only cut down the power off current to about 170uA and it is too big). The 3rd point is about whether it is a bug or feature when the circuit starts in the on state: In the case of my UT61E mod, it can be a wanted feature. Best Momentary Latching Pushbutton Switch Circuit | All ... honestly im really liking this dual schmitt trigger circuit. just add 2 resistors, a cap and a mosfet and youre done. i ended up ordering the exact parts listed in the diagram, because after comparing datasheets for hours the ones listed really are the best fit for what i want. i was tired of spending the 1200% ratshack tax too. Latching Momentary Switch Circuit Daycounter Latching switches are more complex mechanically, larger, and more expensive. The circuit below creates latching action from a momentary switch. When the circuit is powered up, all of the transistors are off and stay off. C1 gets pulled up to Vp. When the switch is pushed, Q3 and Q2 turn on, since their base is pulled up. IRF7319 dual Mosfet Latching switch Page 1 Nice, adding a 1K resistor across the load has got the original circuit almost functional; but still when initial power is applied the circuit is on instead of off, although subsequent switch presses work as intended.
