The 235 family provides a single row of spring-connected terminal positions with solder pins for PCB mounting. Eight models cover six pitches. Standard 235 versions have raised actuation levers; the 235W versions have a 9.75mm-high body without raised levers. Select the exact model and pitch before defining the PCB footprint.

Dimensions are in millimetres. N is the pole count. All eight models have two rows of solder pins at 5mm row spacing and nominal 1.20mm PCB holes. Solder tails are 3.60±0.30mm. A single row of terminal positions should not be confused with the two pin rows.

The four smaller-pitch lever models use a 3.15mm side-view pin-to-body edge offset; both W models and the 7.5mm and 7.62mm models use 3mm. Use the individual drawings for longitudinal end allowances and pin-centre datums.
Individual dimension tolerances take precedence over these general values.
