I’ve already lost the spring from one of them!

Terminal positions 1 and 2 (across the centre, almost) are for the lamp, and 3 and 4 in the corner are the pole 1 reed unit. They would be capable of DPST operation if fitted with a second reed, and a modified base with the additional terminal holes on the opposite side from 3 and 4.

Travel is 4.5 mm. Force is hard to measure, as head-to-head press tests are ruined by how juddery they are, even though they feel smooth. They seem to be heavier than MX Black, and possibly lighter than MX Linear Grey.
