No power flows in the switch on the right. It is missing a connector when compared to the working switch on the left. Is this missing connector just a jumper? Can I just solder across to complete the connection?

    I think mudguts is the resident expert on switches

    No, Tapatalk says this can't be changed.

    All depends on what P03 does

    0.3 ohm resistor?

    That's the problem it may be a component, diode, capacitor, resistor, etc.. I can't tell from the picture.. If it was just a jumper then yes you could just solder across however I doubt it is.

    What is this out of?

    It is a switch for a battery compartment on a toy gun.

    P03 is likely a diode or a transistor (hard to tell from the photos) and replacing it with a jumper will probably not work, might even short out the battery. Not recommended.

    Get the kid a metal lathe.

    Don't you know about free trade? It's cheaper just to buy a new one. Go to the dollar store.

    Actually with the P designation I think this is a type of diode or mosfet which are typically used in low voltage, power management applications which would likely apply here. At least back a few years they were.

    On an ohmmeter a diode would read infinite resistance though, no?

    It's a resistor equipped transistor (PNP digital transistor), they can be purchased at Sayal Electronics (1040 Fountain Street,Unit 3-4 Cambridge, Ontario)...

    Thanks, what is it's purpose?

    $ave space and simplify circuit design...
  • moosemoose
    Ok but why is it there?

    ...to simplify the circuit, decrease the use of multiple components.

    here ya go Resistor :D
  • moosemoose
    Can you point me out what I should be looking for?

    My component doesn't seem to have 3 legs like the images at Sayal.
