A set of 80 vertical SPDT slide switches in eight sizes rated 0.5 A at 30 V for Arduino and breadboard projects
This kit contains 80 vertical micro slide switches in eight size variants covering 3 mm to 6 mm handle heights. Each switch is a single-pole double-throw device rated for 0.5 A at 30 V with a 100 000-cycle electrical life. Through-hole pins and panel-mount brackets suit breadboard and PCB prototyping work.
Hobbyists and students building Arduino or breadboard circuits gain a ready range of footprints without sourcing separate part numbers. The 2.5 mm and 3 mm pin pitches fit standard perfboard spacing. Builders who require surface-mount devices or higher current ratings will not find suitable parts in this set.
Gold-plated contacts and a sliding mechanism rated beyond 100 000 operations keep contact resistance stable through repeated toggling. The vertical orientation reduces board height while the screw-fixing holes on select variants prevent mechanical loosening during extended vibration or handling.

You need a soldering iron, solder, and a printed circuit board or perfboard drilled for 2.5 mm or 3 mm pin pitch to mount the 80-piece SPDT switch assortment.
Yes, the 30 V / 0.5 A rating of every switch in the kit exceeds the 5 V logic rails of an Arduino, so they can be wired directly to digital pins for on-off control.
Use a multimeter in continuity mode across the three terminals; sliding the actuator should toggle the connection between the common pin and each throw with a firm click, repeating for over 100 000 cycles.
