Product Overview
The 1607233480 Electronics Module is a precision-engineered direct-fit switch and controller replacement for 18V brushless impact wrenches built on the GDX / GDR / GDS platform. This complete electronics module – also referred to as an “electronics module,” “switch assembly,” or “electronic module” in parts diagrams – is the central control interface that manages motor speed, electronic functions, and trigger response.[reference:8][reference:9]
Designed for professional repair technicians and equipment maintenance specialists, this module restores factory-spec performance to tools exhibiting intermittent operation, complete failure to start, erratic speed control, or loss of electronic functions.[reference:10] The OEM-spec electronics module delivers smooth, proportional speed control and manages the electronic functions of the brushless motor – restoring the fine-touch precision required for driving fasteners without stripping or over-torquing.
This genuine OEM-spec module is crafted to meet the highest standards of quality and performance, playing a vital role in managing the electronic functions of your impact wrench and contributing to its efficiency and longevity.[reference:11] It is specifically engineered for the Bosch GDX 18V-LI series and compatible GDR / GDS 18V brushless impact wrench platforms.[reference:12]
This module is referenced under OEM part number 1607233480 (also formatted as 1 607 233 480 or 1.607.233.480) and is the direct replacement for the original equipment module in compatible 18V brushless impact wrenches.[reference:13]
💡 Pro Tip – Pre-Installation Diagnostic: Before replacing the electronics module, perform a simple test. With the battery removed, inspect the module for visible damage – burns, cracks, or discoloration indicate failure. If the tool fails to start or runs erratically, test the battery and tool contacts first – clean them with an eraser. If the problem persists, the electronics module has likely failed. Note that this module controls the brushless motor electronically – if the motor runs but lacks power, the issue may be the module rather than the motor itself. Always remove the battery pack before beginning any disassembly.[reference:14]

Teardown & Replacement Workflow
Compatibility – Cross-Reference & OEM Part Numbers
Compatible with Bosch GDX 18V-LI, GDR 18V-LI, GDS 18V-LI, and related 18V brushless impact wrench variants. Also compatible with models 24618, 25618, and IWH181.[reference:25][reference:26]
Diagnostic Q&A
❓ Q: My impact wrench doesn’t start with a fully charged battery – is this definitely an electronics module problem?
A: Not always. First, clean the battery and tool contacts with an eraser – corrosion or debris can prevent power delivery. If the problem persists, the electronics module is the likely culprit. Unlike brushed tools where the switch is a simple mechanical contact, brushless tools like the GDX / GDR series rely on this electronics module to control the motor. If the module has failed, the tool will not operate.[reference:27]
❓ Q: What models are compatible with the 1607233480 electronics module?
A: This electronics module is compatible with GDX 18V-LI, GDR 18V-LI, GDS 18V-LI, and related 18V brushless impact wrench variants. It also fits models 24618, 25618, and IWH181. Always verify your tool’s model number against the compatibility list before ordering.[reference:28][reference:29]
❓ Q: Does the 1607233480 electronics module include the trigger switch?
A: Yes. This is a complete electronics module that integrates the variable-speed trigger switch, control board, and wiring harness. The module installs as a single unit – no additional switch components are required.[reference:30]
❓ Q: What is the difference between 1607233480 and a standard mechanical switch?
A: 1607233480 is an electronics module – not a simple mechanical switch. It contains the electronic speed controller and logic board that manage the brushless motor’s operation. Brushless tools require this electronic module to function; a standard mechanical switch cannot be substituted. This module is specifically engineered for the Bosch GDX / GDR / GDS 18V brushless platforms.[reference:31]
Safety Notes
- 🔴 Always remove the battery pack before beginning any disassembly or electronics module replacement procedure.
- ⚡ Exercise caution when handling electronic components – the module contains sensitive electronics. Wear ESD-safe gloves to prevent static discharge damage.[reference:32]
- 🔧 Note wire routing before disconnecting – the harness must be routed exactly as original to prevent chafing or pinching.
- 🧤 Use correct torque values – housing screws typically require 0.8-1.2 Nm (7-10 in-lbs). Over-torquing can strip housing threads.
- 📐 Verify module alignment before final assembly – the trigger must sit correctly in its housing channel for proper operation.[reference:33]
- ✅ Perform a function test before full reassembly – insert battery and verify smooth variable-speed operation and forward/reverse function.
A: First, clean the battery and tool contacts with an eraser. If the problem persists and the tool fails to start, runs intermittently, or exhibits erratic speed control, the electronics module (1607233480) is likely the issue. Unlike brushed tools, brushless impact wrenches rely on this module for motor control – a failed module will prevent the tool from operating correctly.
A: Yes. 1607233480 is the OEM electronics module for GDX 18V-LI, GDR 18V-LI, GDS 18V-LI, and related 18V brushless impact wrench platforms. This is the correct direct-fit replacement across all compatible models.
A: 1607233480 is an electronics module – not a simple mechanical switch. It contains the integrated speed controller and logic board that manage the brushless motor’s electronic functions. Brushless tools require this module to operate; a standard mechanical switch cannot be substituted.
A: Yes. This is a complete electronics module that includes the variable-speed trigger switch, control board, and integrated wiring harness with the correct OEM-spec connector. The module installs as a single unit.
