Trying to find DIP switch selector
Melon:
Hello everyone, my questions are: Are there any single-pole, multiple-throw DIP switches? If so where can I find them?
Not the ones with only two throws (SPDT), but many of them. My purpose is to make a clock selector from a binary counter to a common output using a slider switch.
This is the only one I have found, a Grayhill 79C10T (see attachment) and I've searched quite a lot. It is also quite expensive.
Why aren't they common?
Greetings.
ledtester:
DIP switches are not very robust and are only designed for infrequent use. The datasheet for the Grayhill switch states:
Mechanical Life: 4,000 cycles maximum. Note:a cycle is one complete operation, back and forth through all switch positions.
A cheaper solution would be to use a 2x10 row of pin headers with a jumper. A jumper with a tab will make it easier to use:
You can find them on ebay by searching for "jumper with handle".
Melon:
Yeah that's true, the jumper solution is definitely simpler and cheaper. I thought I could make a better looking board using switches instead of jumpers but now I see why these switches aren't common.
Thank you for the answer.
tooki:
So... if you are willing to use jumpers (which provide no protection against someone using multiple jumpers at once), you could just use ordinary DIP switches and write "SELECT ONLY ONE" next to them.
ledtester:
But if there is only one jumper there is a good chance they will move the existing jumper rather than add another one.
