But if I mount it freestanding on a PCB, the force will be transferred to the connector pins of the switch and thence to the PCB. Switches like this NKK are intended for panel mounting, hence the (admittedly small) force required to toggle the switch would be transferred to the panel. These switches will be operated relatively infrequently. and not too close to anything where a momentary short could cause damage. My thinking is to install the switch as a 2-pin through-hole component. You can lay your board out, hit the button, and have boards in a week or so. The PCB will not need its own enclosure because it will installed in a larger enclosure and fastened to the wall of the larger enclosure.Īt the moment I lean toward using an NKK Switch (or something similar) as shown on the DigiKey web site at. The switches will be SPST ON-OFF in 12VDC, 0.5 amp circuits. But, this all hinges on the definition of “thing” which may.I'm developing a small PCB on which will be installed 6ea toggle switches (among other things).

Well, if one considers the vast expanse of the nonexistent, assuming it does not exist in some alternate dimension, there are many things that never had a beginning.
