I'm working on adding extra access control to elevator calling buttons and i would like to identify the connector type of the wires connecting elevator buttons to the elevator panel

I have tried Micro JST 1.25MM 3-Pin Male & Female Connector Plug, it has the same Pitch Mating size of 1.25mm but unfortunately the connector itself is smaller than the original one.

    \$\begingroup\$ You threw me off and sent me down the wrong path for 10 minutes with your incorrect dimensions. The pitch of the original connector is 1.5 mm, not 1.25 mm. \$\endgroup\$ Commented Jun 15, 2023 at 12:00

I found it with my Identiconn utility.

It's a JST ZH: 1.5 mm pitch.
