Original Bosch soft-start module, part number 1609B05214 — the electronic start-up control used in Bosch GCM 8 SJL slide mitre saws.

This compact start-up module (listed as position 233 in the GCM 8 SJL parts diagram) smooths the motor’s initial power-up, cutting inrush current and reducing stress on the armature and switchgear so your saw starts gently and lasts longer.

Direct-fit replacement for the GCM 8 SJL family (check your machine’s type/serial to confirm compatibility); it’s the same original Bosch control unit you’ll find in the exploded parts listing for that model.

If you keep Bosch power tool spare parts on hand for repairs, this genuine Bosch soft-start module is the specific part to restore reliable, low‑surge starts and prevent repeat motor damage.
