What happens if I run 1A through a 50mA rated switch for 5 seconds, one time only?

The picture is showing a typical, miniature tactile switch, rated for 50mA. This switch suits my application perfectely, the only problem is that it's only rated for 50mA. My application contains 2xN batteries in series (N=1000mAh, 1.5V). What will happen if I run 1Amp through the switch for, let's say 5 seconds, one time only? The whole device is disposable, so the switch will only be used once. Will the switch manage one time use with this current, or will it break down? Are there other switches of this dimension that are rated for 1amp? I haven't managed to find any. Thanks in advance.

Looking for the right type of switch to use....?

Hi, I'm trying to build something that might best be compared to a manually controlled speech timer with a green, yellow and red light. I only want one light on at a time, or all off. What is the best way to control this without having a single switch for each light? Am I describing something that would be classified as "single pole, quadruple throw?" Best place to find this switch? Thanks!

What kind of switch am I looking for?

Please help me out by telling me what I need to look for, or whether or not it exists simply. Thanks I want a switch that when I push it, it goes from the first throw to the second, but when the power goes off, it'll go back to the first throw. The application is an idea I want to make for a small car light. There would be two switches, an on/off, then this switch, which would default to a row of red LEDs but when you hit it would go to a row of white LEDs. Then when you turn the power switch off, next time you turn it on, it would light up the reds. I racked my brain to find an example, and the best I could come up with is from a camping headlamp. You press it deep and it turns on, then you half press and it'll switch to a dimmer setting. But it'll always start at the first setting. Maybe I should just get a cheap headlamp and cannibalize the switch, but I think that'd be wasteful (and probably not so cheap). Make sense? Thanks in advance for any ideas. This is my first attempt at synthesizing something, and I've been wanting this for awhile.

I need some help an an ignitor box (loook in details)? {REMADE}

Alrighti posted this before but it seemed like people didnt understand what was going on. Altight, we have a box and our first switch is a rolling switch (SWITCH 0) that is used to make sure that it only works if the box is closed. Then we have a series of 5 switches that are basic on off switches {SWITCH 2, 3, 4, 5, 6) and the switches are used for how many ignition we wish to do at one time but these switches have to be switched in order so example we cant turn on switch 3 without first flipping switch 2 and etc but these switches will light a light a soon as there flipped on still with the rule that the previous switch must be switched first also the switches run a positve current throu our first alligator clips of the ignition cords. then we have a main switch (SWITCH 7) that has a cover as a safety and this will also turn on a light and this switch will run current to our last switch (SWITCH 1) which is a momentary push switch that will run the negative current to the second alligator clips of the ignition cords thus setting off what was wished to be ignited. but we have the problem of the current bypassing (LOOK AT THE PICTURE) so therefore switch 7 isnt needeed bet yet it only is used to light up our (LIGHT 6) so we need to figure out how can we prevent this from happening without completely rendering our circut.

Motion Sensor to Control both Bathroom Light and Fan?

My bathroom currently has two single pole switches mounted in two separate wall boxes side by side with a single double-wide switch cover.  I want to convert these to motion sensor switches with separate vacancy delays for the light and fan so that I can let the exhaust fan run for about 5 minutes after vacancy while the light is set for maybe 30 seconds. Are there commercial switches that will accommodate these two functions in a single switch, or will i need to use a separate switch for the light and one for the fan?  Are there single double-wide wall plate covers that will fit side by side switch placement? Thanks.

How to hook up 2 LED each with their own toggle switch to a battery? Answered

Im looking to install two toggle switches in my car. when the switch is placed in the on postion i want a LED light to turn on. I planning on using one red led light 1.8v 20ma and one yellow light 2.1v 20ma. Where im getting lost is the toggle switch has three metal tab label power acc and ground. Looking at using a 9v for the power source. So what the best route to wire this up. Or should i just use a seprate power source for each light and switch. As for the three tabs on the switch i guess that the postive wire goes to the power, but then would the acc go to the led postive side, and both the switch ground and the led ground go to the point on the power?

Fun uses for Reed Switches?

Reed switches are electro-mechanical devices that opens or closes a circuit when a megnetic field is present. They come in normally open and normally closed designs and range from the size of a grain of rice all the way up to several inches long. A relay, another electro-mechanical device, is comprised of a reed switch and an electromagnet trigger built into one housing. Common uses for reed switches (not counting relays which are used in virtually all electronic devices) include the 'pick ups' on bicycle computers and the sensors on window and door alarms. I just ordered a bunch of reed switches and I need your help in coming up with ideas for what to do with them. Post up your ideas for some things that could be made or modified to be triggered by a magnet coming in close proximity to a reed switch. Remember- the magnet does not have to touch the switch, just get close enough that the magnetic force trips the switch. The stranger and sillier your ideas are the better. Note: this is not a contest and there are no prizes. by posting an idea you are giving your consent for anyone who reads it to use your idea. Posts about integrating reed switches into knex firearms will be ignored (no offence, it's just not my cup of tea).
