Genuine Bosch on/off switch — part number 1609B04211. Direct replacement switch assembly for Bosch sliding mitre saws in the GCM 8 (for example GCM 8 SDE and GCM 800 / GCM 80 SJ) - Check your 10 digit version number from the side of he machine to confirm fit before purchasing goods.

What it is: a factory Bosch on/off (Ein/Aus) switch module assembled to fit the saw’s switch housing and connector block — the same form and mounting used on the original tool. It restores reliable power control and the saw’s normal start/stop function without reworking the wiring.

Notes: this switch is the part specified for the GCM 8 SDE (tools in that range are specified for 230–240 V mains), so check the type plate on your saw to confirm model/voltage before fitting. Installation is a direct replacement — isolate the tool from the mains, remove the switch cover, unplug the connector and swap the module.

If your saw’s type number matches any of the GCM 8 / GCM 800 series, then this genuine Bosch 1609B04211 is the correct on/off switch to restore proper operation.
