A snap action limit switch is a mechanical switch that sends a rapid transfer of contacts from one position to another. The actuator styles are lever actuators that can be straight or formed; a pushbutton actuator, sometimes called a plunger style; and a roller style actuator that can be an actual or simulated roller. Also known as micro switches, snap action switches can be momentary or maintained contact and come in subminiature, miniature, and standard styles. They are typically composed of thermoplastics, plastics, or metals. Snap action switches are useful in situations where a fast opening or closing of a circuit is necessary, such as a mouse button or an appliance setting.

The new current rating options include 10, 16,20, Und 26 amp versions. These switches are designed to convert a mechanical action into an electrical one. This makes them very suitable for applications such as home appliances and factory automation as well as other domestic and industrial uses.TE’s snap action switches are designed to industry standard sizes, making them extremely suitable for use in existing designs. They are available with various contact styles to aid flexibility

Hebel -Momentan -Snap -Action -Switch, Auch als Mikrogrenzschalter bezeichnet, ist ein elektrisches Gerät, das die Schaltkreise entsprechend der Reiseposition der beweglichen Teile wechseln kann. Sein Arbeitsprinzip ähnelt dem des Druckknopfschalters, und beide sind Master -Elektrogeräte. Verschiedene Tasten werden von Menschen manuell kontrolliert, Während Hebel -Momentan -Snap -Aktionsschalter eine externe mechanische Kollisionskontrolle erfordern. Hier sind seine Textsymbole und grafische Symbole.

We see the actual display, disassemble the outer cover of the switch, and there is a sealing gasket on the outer cover to prevent oil from entering. There are four contacts inside, one group of normally open and one group of normally closed. When the external mechanical impact rocker arm switches, the normally open point closes and the normally closed point opens.

In actual work, the Lever Momentary switch is installed in a pre-arranged position. When the moving parts of the production machinery hit the actuator outside the lever momentary switch, the contacts inside the lever momentary switch move to switch the circuit. It is used to control the movement of the workpiece or to perform terminal limit protection to avoid collision accidents.

Types and applications of lever momentary snap action switches
There are many types of external actuators for lever momentary switches, which can meet the installation and application of different applications.

We introduce the most commonly used direct-acting and roller types.
First, see the direct-acting type: when the moving mechanical part vertically hits the actuator of the lever momentary switch to a certain depth, the internal contact state is changed.

Then see the roller type: when the moving mechanical part presses the roller of the lever momentary switch from the left or right to change a certain angle, the internal contact state is changed.
