OBD2 1-to-3 Splitter Cable with Power Switch

Permanent-fit electronics breed under a commercial dashboard: the tracker, the DVR, the driver-behaviour box. This 1-to-3 splitter feeds all of them from the one OBD2 port and adds the feature fleets actually ask for — a master power switch that takes every branch dark in one flip, so a parked vehicle stops feeding standby electronics.

Wiring is full pass-through on all 16 pins across all three branches, built with RoHS-compliant materials and rated -30 to +90 °C for the full climate span a windscreen-mounted box endures. The switch sits inline on the trunk where a driver can reach it without a torch. For benches without the switch need, the plain 1-to-3 variant shares this build.

FAQ

Does the switch isolate all three branches?
Yes — it is a master switch on the trunk; one flip removes supply from every connected device.

Can one branch stay always-on?
Not in this configuration — the switch is common. Ask for the per-branch switched variant if you need a live branch.
