Snap action limit switches are particularly useful for applications that require quick response times in practical situations. These switches permit a device or system to be triggered with a single action, allowing it to be quickly activated or deactivated without physical contact. Common uses of snap action switches are in the control of machine tools, oil and gas operations, instrumentation and emergency lighting.

There are several types of snap action switch available. Some of the most common are pin-lever, plunger, handle, and toggle styles. Pin lever switches operate using a lever that is attached to a pin that is pushed into a small hole when the switch is triggered. Plunger-type switches are used quite often, and operate when a plunger is pressed into a housing, triggering the switch. Handle and toggle switches are less commonly used, but can be more effective for having more control when necessary.

The underlying principle of snap action switches lies in the use of a combination of inertia and gravity to create a momentary disconnect in a contact system. When the switch is triggered, a cam or lever is activated which causes rapid movement of a ball and contact point which slightly releases the electrical circuit. As the motion of the ball contacts the spring and the inertia changes direction, the ball is thrown back into the path of the contact, forming a new connection and restoring the electrical circuit.

When selecting the correct snap action switch for an application, there are several things to consider, including size, type, rating, and contact function. Size is the first consideration, as a correctly-sized switch will be more effective and efficient. The type, including pin lever, plunger, handle, and toggle types, also should be taken into account. Additionally, it is important to factor in the switch’s ratings, determining the current and circuit requirements needed to safely operate the switch. Finally, the contact function should be identified, whether normally closed, normally open, or momentary.

Snap action limit switches are incredibly useful in numerous applications, from controlling machine tools and instrumentation, to oil and gas facilities and emergency lighting. By leveraging the combination of inertia and gravity to create a momentary disconnect, these switches are able to offer quick response times for a variety of tasks. Taking all of the appropriate considerations into account when selecting a switch will help ensure an efficient and effective operation.
