General Purchase & Comparison Queries
Is this switch compatible with my Ideal angle grinder?
This Ideal Switch Spare Part (Part No. 20197) is specifically designed for the Ideal AGH125-B and G15SA2 angle grinder models. If your grinder carries either of these model numbers, this is the correct OEM replacement switch. We recommend verifying your model number on the grinder’s label before purchasing.
Is this a genuine Ideal spare part or an aftermarket alternative?
This is a genuine OEM Ideal spare part manufactured to the same specifications as the original switch fitted at the factory. Unlike generic aftermarket switches, it guarantees a precise fit, correct electrical rating, and the same safety performance as the original component — protecting both your tool and your warranty.
Is it more cost-effective to replace the switch or buy a new grinder?
In most cases, replacing the switch spare part is significantly more economical than purchasing a new angle grinder. A faulty switch is one of the most common and straightforward repairs on power tools. Fitting a new OEM-grade switch (Part No. 20197) restores your grinder to full working condition at a fraction of the cost of a replacement machine.
Product-Specific and Usage Queries
How do I install the Ideal Switch Spare Part on my angle grinder?
The Ideal Switch Part No. 20197 is designed as a direct drop-in replacement for the original switch on the AGH125-B and G15SA2 models. Installation typically involves removing the grinder’s handle housing, disconnecting the old switch terminals, fitting the new switch in the same position, and reassembling. Always disconnect the grinder from the power supply before beginning any repair work. If unsure, consult a qualified power tool technician.
What does the locking mechanism on this switch do?
The positive-locking on/off mechanism is a critical safety feature that prevents the angle grinder from being accidentally switched on during handling or storage. It requires a deliberate two-step action to engage the motor, significantly reducing the risk of unintended starts — an important consideration when working with a high-speed 125mm angle grinder on demanding cutting and grinding applications.
What is included with this spare part?

Problem/Solution-Oriented Queries
My angle grinder won’t turn on — could the switch be the problem?
Yes, a faulty or worn switch is one of the most common reasons an angle grinder fails to power on. Symptoms include the grinder not responding when the trigger is pressed, intermittent power loss during use, or the switch feeling loose or unresponsive. Replacing the switch with a genuine Ideal Part No. 20197 is the recommended first step before considering more extensive repairs.
My grinder switch is stuck in the on position — is this dangerous?
A switch stuck in the on position is a serious safety hazard and the grinder should be disconnected from the power supply immediately and taken out of service. This is typically caused by a worn or damaged locking mechanism inside the switch assembly. Replacing the switch with a new Ideal OEM spare part (Part No. 20197) will restore safe, controlled operation and should be carried out before the tool is used again.
The grinder cuts out intermittently during use — can a new switch fix this?
Intermittent power loss during operation is frequently caused by worn or corroded internal switch contacts that fail to maintain a consistent electrical connection under load. Fitting a new Ideal Switch Spare Part (Part No. 20197) with fresh, high-conductivity contacts will typically resolve this issue, restoring stable and uninterrupted power delivery to the grinder motor.
