## Before you buy

- Listing details are inconsistent or unclear: the title specifies 125V 16A, while feature text gives multiple AC and DC ratings and says 250V/10A or 16A. The title and switching details indicate a 125°C trip with 105°C reset, while another specification section gives a broad 110-240°C operating range and several possible accuracies. Confirm the exact variant and rating against the original part. Details describing X-10 connectivity, touch control, and temperature sensing as a power source are not explained for this passive thermostat. The claimed compliance marks and manufacturer specifications are listing claims, not independently verified here.

## In the box

- 2 KSD301 thermal switches (Included)

## A good fit for

- Repairers matching a normally closed, auto-reset thermostat to an appliance’s existing trip temperature, electrical rating, terminals, and mounting points.
- Replacement applications such as heaters or small appliances where an automatic over-temperature cutoff is required and the original part’s specifications match.

## Less suited to

- Applications requiring a normally open switch or manual reset.
- A replacement decision based only on the KSD301 model name without confirming trip temperature, voltage/current rating, terminal fit, and mounting dimensions.

## Customer feedback

The supplied evidence contains only a small set of aggregate ratings, all in the five-star category. That is a positive but limited signal and does not explain customer experiences or establish performance. For a replacement thermostat, matching the exact switching temperatures, ratings, and physical fit matters more than the rating summary.

## Frequently asked questions

### How does this normally closed thermostat operate?
The listing describes contacts that are closed normally, open at 125°C/257°F, and reconnect at 105°C/221°F after cooling, with ±5°C stated tolerance.
### Will it fit my appliance?
Compare the original switch’s electrical rating, trip and reset temperatures, terminal width, hole spacing, and overall dimensions. The listing specifies 6.3mm terminals and 23.8mm hole spacing.
### Is the package a single switch or a pair?
The included-components field and package-content text both state two KSD301 thermal switches.
### Can this replace a normally open thermostat?
No. This is listed as normally closed. Choose a normally open type only if that matches the original circuit and application.
