Question about Tact switches?

[kaos731]

I Want to use a tact switch for my mod box ( I like the clickyness) but I am confused about how to wire this up.

The tact switches have 4 leads instead of the customary 2 leads that normal switches have.

12VDC 50mA SPST 6.2x6.2 mm SMT Tact Switch, 9.5mm High - RadioShack.com



Can anyone tell me how to wire this up?
Do I just bridge the leads on either side and wire like a 2 lead momentary switch?

Here's my , until one of the electro-wizzes shows up:

First off, tact switches are low amp switches. You'll need a mosfet or voltage regulator with a control pin. Typically these switches are rated at 50 mA.
The pins are in pairs, I believe you only need to connect one pin on each side.

TomCatt is absolutely correct.

Here ya go.

wait but it says 12volts @ 50ma. My mod box is only throwing 3.7 volts at a range of 2.5 -3.0 amps.

Are amps a bigger current than mili-amps?

and what is a "mosfet" where do I get one and how do I wire that up in relation to the switch?


Sorry for all the questions but I am a new modder and stepping away from the "safe & easy" standard 125volt @ 3.0 amp switches I've been using.

yes there are 1000ma in a Amp hence "milli"amps .You will need a mosfet for any tact switch or low amp momentary switch . Some chips like the okr-t have a control(on/off) pin so you can run a tact switch instead of need a high amp switch . The control pin only needs a few ma to turn on the chip then it gets its normal power from the Vin pin

I was woundering about this, with the original question. So I would have to wire the mosfet chip before the switch, almost like a resistor?

Here is a link to a diagram, just attach the tact switch instead of your finger..
