Hi guys,
Have a few questions regarding switches, namely what considerations are important when selecting a switch?
1.) I noticed there are ebay sales of 40 switches for a total price of 5 dollars and then other places where you would be paying 3 dollars per switch (Panasonic switches) but still, why the discrepancy? Is it worth paying the extra? Does the age old adage of you get what you pay for come into play here?
2.) What about the electrical specifications? I've got very basic knowledge about electronics (just experiments at school etc and some other minor things) so I don't quite know what to look for when it comes to selecting an appropriate switch. Granted! I need to provide a circuit diagram for more specific advice, which I don't yet have, but was wondering what initial impressions people had about something like this:
Actuator Type Lever
Contact Configuration DPDT-2NO/2NC
Contact Current Rating 0.2 A @ 14 V dc
Maximum Operating Temperature +80°C
Minimum Operating Temperature -30°C
Switch Operation Latching
Terminal Type Solder
Is the 0.2A current the max current that this switch can take and same goes for voltage? 0.2 seems small, no?
3.) What about the pins? There are usually 6 from what I see. Where can I find what each pin does? Can't seem to find anything on this.
This circuit diagram on page 2 looks completely nonsensical to me:
