Switch input mode with jumper

thread240-386573

Switch input mode with jumper

Switch input mode with jumper

(OP)
Could anyone suggest switch/input selector for mounting on PCB (through-hole)? Device have two inputs, Mic and Lin-in input. Capsule Micro Electret Mic Ø10mm in mounted on PCB, Mic is default input mode. When I need switch to Line-in input, I just put jumper. Or maybe some other small handy switch.

RE: Switch input mode with jumper

Only thousands of PC mount switches out there..
www.digikey.com and start searching for the exact size/rating/button type,etc.. that you need

RE: Switch input mode with jumper

An internal jumper?

Just use the 0.1-inch spacing header pins and the sort of block-jumper as so often seen in PCs.

RE: Switch input mode with jumper

Don't they make 1/8" plug sockets with switches, so that plugging in the line input could switch off the mic?

Yes, internal jumper, or DIP switch. DIP switch perhaps better, I need SPDT DIP Switch (ON-ON, without center position). Searched on Digikey, but still didn't find good accurate one. The line-in input is Terminal block, not 1/8" plug socket, and Mic is on board.

RE: Switch input mode with jumper

Accurate? Switch? What "accuracy" spec are you imposing on the switch?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!
There is a homework forum hosted by engineering.com: http://www.engineering.com/AskForum/aff/32.aspx

Hint: You get better suggestions, sooner, and waste less of our time and yours, when you bound the problem space as completely as possible with your initial question.

well, I mean internal switch on PCB (J4)

Mainly, just low profile and reliable, low PCB space.
