Several current product listings confirm 16A/250VAC for KCD-4 4-pin versions; some specify 20A/125VAC as well.
Dimensions
A commonly sold KCD-4 version measures approximately 31–33 mm × 25 mm × 30–34 mm, depending on the housing and terminal/indicator configuration. One listing gives 31 × 25 × 34 mm, while another gives approximately 33 × 25 × 30 mm.

Length 31–33 mm
Width 25 mm
Height 30–34 mm
Panel Cutout Approx. 31 × 22 mm
Number of Terminals 4
Important: KCD-4 dimensions are not completely standardized across manufacturers, so the panel cutout should be checked against the actual supplier drawing before production.
Material Specifications
Component Typical Material
Housing Flame-retardant thermoplastic
Rocker Polycarbonate / thermoplastic
Terminals Brass / copper alloy
Contacts Silver alloy / copper alloy
Terminal Finish Tin plated
Spring Stainless steel / spring steel
4-Pin DPST Working
The 4-pin version has two independent switching poles.
OFF:
Pole 1 → Open
Pole 2 → Open
ON:
Pole 1 → Closed
Pole 2 → Closed
This allows the switch to disconnect two circuits simultaneously, which is useful for switching both sides of a supply where a DPST configuration is required.
