Tact Switch 6*6mm 7mm Through Hole SPST-NO

This switch fits perfectly in .1 inch prototyping boards, and makes a nice reset button for ATMega microcontrollers. Arduino fans take note.

Note that two of the pins are connected, with the other two making separate contact with the connected pair. Ground the connected side when using to reset ATMega devices, connect one of the independent pins to the reset pin, and drive it high with a 10K pullup resister. Works every time.

Small tact switches, good for small pulses, resetting/setting etc. especially on different logics.
