D2HW-BL233M

Snap Action, Limit Switches

The D2HW-BL233M is a Type 1-Form C snap action, limit switch (commonly referred to as a "mouse switch") used in a wide range of industrial, commercial and residential controllers and applications. The switch is designed to provide dependable switching action in response to physical movements and pressures in controlled environments. When properly installed and used, the D2HW-BL233M switch can provide a consistent signaling mechanism in many common and specialty systems.

Application Field

A limit switch is designed to provide a feedback signal when certain conditions are met, and so the D2HW-BL233M can be used in a variety of applications. The D2HW-BL233M is particularly useful in applications where it is necessary to detect a simple movement or physical pressure. This includes control systems for machines, control of electric motors, door interlock switches, stair lighting and lift control systems, security system control, and other systems where a reliable and consistent signal is necessary.

The D2HW-BL233M can be used in other settings as well, making it an invaluable component in many unique systems. Some examples include emergency shut-down systems, industrial automation, medical device forms, medical emergency equipment, and other industrial grade applications.

Working Principle

The D2HW-BL233M has a set of contacts that, when tripped, provide an electrical signal indicating a physical change was detected. The switch is triggered by a mechanical lever being pressed against the contact, causing the contact to close and a signal to be generated. The signal can either be a direct output from the contact itself, or it can be connected to a circuit that amplifies the signal to a more useful level.

The switch is designed to be precise and repeatable in its triggering, so that the same physical events will generate the same signal output every time. This enables it to be used in a wide variety of applications as an input device as well as an indicator switch or as a safety or reliability switch.

The D2HW-BL233M limit switch is an extremely reliable switch, providing years of dependable service when properly installed and used. The switch is rated to a maximum load of 5A 120Vac and is UL listed, making it an excellent choice for many industrial and commercial applications.
