1. External & Bezel Dimensions
These measurements define the visible part of the switch once it is installed on a panel:

– Outer Bezel Diameter: 23 ± 0.20 mm.
– Total Height (Unpressed): 25.7 ± 0.30 mm from the top of the rocker curve to the tip of the pins.
– Rocker Diameter: Approximately 19.8 ± 0.20 mm.

2. Mounting & Housing Dimensions
These dimensions are critical for ensuring the switch fits into your project enclosure:

– Main Housing Diameter: The body directly below the bezel is 19.8 ± 0.20 mm.
– Lower Body Diameter: The base tapers slightly to \Phi 19.3 mm.
– Insertion Depth: The distance from the bottom of the bezel to the base of the housing (excluding pins) is 17.8 mm.
– Housing Width (with clips): 20.5 mm at the widest point of the tension clips.

3. Terminal (Pin) Specifications
The switch features three metal terminals for electrical connection:

– Terminal Width: 4.8 ± 0.05 mm.
– Terminal Thickness: 0.8 ± 0.03 mm.
– Terminal Spacing: 14 ± 0.10 mm between the two outer pins.

4. Panel Cutout Requirements
To install this switch, your mounting surface must meet the following criteria:

– Cutout Diameter: A circular hole of ø20 mm.
– Alignment Notch: A small notch 2.2 mm wide and 1 mm deep (making the total vertical cutout 21 mm) is required for the orientation tab.
– Panel Thickness (t): Suitable for materials between 1.0 mm and 2.5 mm thick.
