9Values Mini Micro Slide Switch Kit (90pcs)

Overview

An assortment box of miniature SPDT (single-pole double-throw) slide switches — the small panel-mount toggle-style switches with a sliding knob, commonly used for power on/off selection, mode selection, or any two-position manual control on a project enclosure. “9 values” refers to 9 different physical variants in the kit (different pin spacing/orientation/knob styles — models like SS12D00, SS12D10, SS12F15, SS12F44), not 9 electrical ratings. Generic part, sold under several reseller names for what looks like the same physical assortment.

Key specs

  • Operating voltage: n/a (passive mechanical switch)
  • Contact rating: DC 50V, 0.5A (typical across this switch family — not confirmed per-variant)
  • Contact configuration: SPDT (1P2T — one pole, two throw positions), 3-pin
  • Pin pitch: 2.54mm (breadboard/perfboard compatible)
  • Contact material: brass, silver-plated (per family spec)
  • Mechanical life: >100,000 actuations (per family spec)
  • Operating temperature: -25°C to 80°C (-13°F to 176°F, per family spec)
  • Mounting: vertical panel-mount with knob, various body styles across the 9 included variants

Pinout

Standard SPDT 3-pin layout (applies to each switch in the kit):

Pin Function
1 Common (pole)
2 Throw position A
3 Throw position B

Sliding the knob connects the common pin to whichever throw position it’s moved toward. No pin numbering is universal across all 9 body styles in the kit — check each switch’s own body markings/orientation before wiring, since some variants have inverted or reordered footprints relative to others.

Wiring / typical usage

Typical use: common pin to signal/power line, one throw position left floating or tied to GND, the other tied to the “on” signal — sliding the switch selects between two states. For MCU GPIO sensing, wire like any other manual switch (pull-up/pull-down as needed); the 0.5A/50V rating is far above logic-level needs, so no special consideration for GPIO-only use.

Code / libraries

N/A — passive switch, read as a standard digital input if driving a GPIO.

Source material

Verification

Inferred from vendor listings only — no manufacturer datasheet exists for this generic assortment class. Contact rating, pin count, and mechanical specs are consistent across every reseller listing found for this switch family, which is a reasonable confidence signal, but none trace back to an original manufacturer datasheet. Piece count (90) confirmed directly by Alex.

Notes / gotchas

  • 9 different physical body styles in one box — don’t assume pin 1/2/3 positions are consistent across all of them; check each switch individually before wiring, especially before drilling panel mounting holes to match a specific footprint.
  • Contact rating (0.5A/50V) is a family-wide figure from vendor listings, not verified per-variant — fine for any logic-level GPIO sensing use, worth double-checking before switching real loads near that ceiling.
  • Used in: Pocket Speaker — one switch, common + one throw pin only, in series with the battery’s + lead as the master power switch.
