New NKK Circuit Board Mounted Key Lock Switches, Keyed Alike, Part Number SK14EG13-RO, or SK14EG13-R0, or SK-14 or SK14. Each bid quantity is for a Lot of Two (2) Switches with Four (4) Keys and Two (2) PVC Cleaning Boots. You may bid / buy any number of lots, up to the total quantity available above.
These were purchased at an industrial liquidation recently, and they were brand new in bulk factory boxes. We repackaged them in heavy Ziplok bags. They are quality little switches with smooth movement and light but easily perceived clicks between positions. No, you can't use them to control your air compressor, but they would be great for light amperage electronic applications. They have three key positions, and the key is prevented from removal in all positions except the Center position. These are Keyed Alike, which means that any of the keys will fit any of the locks. Contacts are SP3T (single pole, triple throw).

According to the manufacturer:
Distinctive Characteristics
Sealed body construction plus disposable boot protect contacts and allow automated processing.
Molded-in terminals seal out flux, solvents, and other contaminants.
Short body size for space-saving, behind panel dimensions. Detent mechanism, with its spring-operated steel ball, gives crisp, positive action for accurate switch setting.
Bifurcated, self-wiping contact mechanism provides unequalled logic-level reliability and smoother, positive detent actuation.
Crimped bracket legs ensure secure PCB mounting and prevent dislodging during automated wave soldering.
.100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing.
