Getting a switch to stay put on a Bread Board can be difficult.

So I designed some break out boards where you can solder the switch to the board
and some pins on the bottom to plug into the breadboard.

A resistor and LED are included on-board and may be enabled or disabled.

.... mouse over the thumbnail to see to which version they apply....

these are labeled as NDP6020 P Channel mosFETs

but test as n-Channel mosFETs..

can't say what PN# they are..
tested with 7.5VDC and a 3V battery to the gate.

5V to 3.3V AMS1117-3V3 Regulator Module

• Input voltage: DC 4.2 - 10 V

• Output: 3.3 V, 800 mA nominal, 950mA Peak

• Size:8.6mm x 12.33mm

These modules have a PCB layout error...
I made the false assumption that the tab was ground...
It is OutPut - you could drill in under the ground pin to cut
the connection...  or...  just desolder and lift it..

Regulators and caps should be good but I assume the regulator
would need to be unsoldered.
