switch question
« on: December 08, 2015, 04:22:50 am »
Hey Guys

I don't know what kind of switch this is, but I need to find a pushbutton switch that is just Mom, so you press it and it returns back, without holding.

What kind of switch is this?

Thanks
Docmur

Momentary.

There are a large variety of switches, so you'd need to be more specific about your requirements for anybody to guide you more than that.

A momentary pushbutton switch?

I thought that was what it was, but on Digikey I search for pushbutton but only see on-Mom,  off-Mom and Mom-on-off.  What I need is a small surface mount switch that is Mom.

Well, do you need it to be momentary ON (off except when pressed), or momentary OFF (on except when pressed) or alternating momentary ON and OFF when pressed repeatedly?

If not otherwise specified, momentary ON is assumed.

Well in this case once the button is pressed, the motor has to fire for 1 - 2 seconds, so I assume that's Mom-on?  I know nothing about switches, thank for your help.

Is the switch directly powering the motor (needs high current) or is it driving a relay or transistor (needs low current)?

You want a Normally Open Momentary Switch.  In terms of digikey's nomenclature, "Off-Mom"

If it's low current, any standard 6 or 12mm surface mount tact switch is what you want.

The switch drives an int pin on the micro to trigger the motor drive :)
