Research Notes

1. Overview

The Marquardt 1245.0201 is a power tool push-button switch from Marquardt Management SE (Germany), the global market leader in power tool switches. It belongs to the 1245 series designed for electric power tools; confirmed siblings include 1245.0301 (2-pole N/O, 4A/250V), 1245.0701 (2-pole N/C), and predecessor 1245.0120. All 1245 variants share 4(4)A 250V~ ratings, screw terminals, and dust protection.

2. User Sentiment

No direct user reviews for the 1245.0201 were found. The 1245 series is a well-regarded aftermarket replacement part stocked by specialist distributors (e.g. Kahlhorn) for Fein, Flex, and Bosch power tool repairs. The 1245.0701 (N/C sibling) was listed as discontinued at Kahlhorn, suggesting the series is mature. No quality complaints or failure reports appeared in available sources.

3. Real-World Applications

Confirmed for electric power tools: angle grinders, drills, sanders, and saws from Fein, Flex, and Bosch. Serves as a trigger-style or push-to-start on/off switch in hand-held power tools. Compact body and screw terminals suit both OEM installation and aftermarket repair. Compliant with IEC 61058-1, UL 1054, and CSA C22.2-55.

Depanare

Button doesn't respond when pressed

Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.

Works intermittently

Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.

Button feels mushy or doesn't click

The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
