LSR7L

Snap Action, Limit Switches

The LSR7L series snap action limit switch is a precision device designed to control the electrical signals on automatic machines or devices. It can be used in such applications as institutional, industrial, automotive, and telecommunications. The basic operating principle of the LSR7L series is that it detects changes in the mechanical environment and produces a corresponding electrical signal to start or stop a machine or device.

The snap action limit switch consists of three major components: the electrical contacts, the actuator, and the housing. The contacts provide the electrical connection between the switch and the actuator. A typical LSR7L switch includes a pair of normally open (NO) contacts, a pair of normally closed (NC) contacts, and a pole. The pole holds the contacts together and provides support for the switch.

The actuator is the moving part of the switch, and is responsible for sensing changes in the environment and activating the contacts. The actuator may be a plunger, lever, or rocker and is usually contacted in a specific direction. Actuators are usually made of metal, usually brass or stainless steel, or plastic. Actuators are often adjustable to account for changes in the environment.

When an external force is applied to the actuator in the contact direction, the contacts open or close, thus allowing electricity to flow through the switch. The LSR7L series is constructed with a two-position snap action and a "floating" return action. This design allows the contacts to snap open and close uniformly in response to mechanical forces. The snap-action mechanism provides quicker operation than a standard limit switch and requires less energy in operation.

The LSR7L switch housing is usually made of metal, usually stainless steel or aluminum. It provides mechanical protection for the switch, as well as providing mounting options for the switch. The housing is usually rated to wide range of temperatures, and may be gasketed, o-ringed, or epoxy-filled to provide water and dust protection.

LSR7L switches can be used in a variety of applications, including industrial, automotive, and telecommunications. Some of the most common applications include motor control, over-travel stopping, vacuum and pressure sensing, door interlock, and internal linkage of machines.

The LSR7L series snap action limit switch is a durable, reliable device used in a wide range of applications. Its quick response and low energy requirements make it an ideal choice for controlling signals on a variety of machines and devices.
