8536.50.90.40 - Snap-action, other than limit

This HTS classification, 8536.50.90.40, pertains to "snap-action" switches that are specifically *not* limit switches. These are electrical devices designed to operate by a quick, sudden movement (a "snap") when a certain threshold is reached. This action is typically characterized by a distinct change in electrical contact status. The primary function of these switches is for making, breaking, or changing electrical circuits, operating at voltages not exceeding 1,000 volts.

The key differentiator for this category lies in the "snap-action" mechanism and the exclusion of "limit" functions. While other sibling categories at this level might cover rotary, push-button, knife, or slide switches, this category is for those whose actuation is defined by a rapid, self-accelerating mechanism that results in a decisive "on" or "off" state, rather than being triggered by physical contact with an object in a linear or rotational path (as in limit switches). For instance, many thermostats and some appliance controls utilize snap-action mechanisms.

As this is a leaf node within the HTS structure, there are no further subcategories to detail. Therefore, the focus for classification under 8536.50.90.40 is on confirming that the switch possesses a snap-action mechanism and that its primary operational purpose is not that of a limit switch. Classification will rely on the demonstrable physical and functional characteristics of the switch itself.
