Snap Action Switches

A snap action switch is a type of switch which is designed to have a very fast operation time when actuated.  It is typically a type of mechanical switch which has one or more parts which move quickly when triggered, resulting in an extremely short switch activation duration.  There are numerous types of snap action switches on the market, and each type provides a different level of speed to suit different applications.

WGLA1A04BB Snap Action Switch

The WGLA1A04BB snap action switch is an economical and reliable choice for many applications. This particular switch is comprised of a contact block, an actuator bar, and a spring.  The actuator bar is embedded in a housing and sits atop a spring.  When the actuator bar is subjected to an external force, the spring forces the arms of the actuator bar apart, closing the contacts of the contact block. A variety of forces can be used to actuate the switch, including mechanical, electrical, hydrodynamic, pneumatic, and magnetic.

Application Fields and Working Principal of WGLA1A04BB Snap Action Switch

These switches are used in a wide range of applications, including industrial motor starters, pumps, lighting controls, compressors, and more.  They are often used as limit switches, proximity switches, and pressure switches, as well as in applications which require an on/off control. The WGLA1A04BB snap action switch is designed to be reliable, dependable, and with superior performance. The snap action feature of the switch ensures quick response times when actuated, and the contact blocks are corrosion-resistant for added durability.An additional benefit of the WGLA1A04BB snap action switch is that the contacts remain closed until the actuation force is removed from the actuator bar. This allows the switch to have a long mechanical life, as the contacts are not subjected to frequent opening and closing. As a result, this switch is often used in applications which require a signal to initiate an action, or to provide continuous output signal. Thanks to its ability to respond quickly, the WGLA1A04BB is also suitable for use in machine automation applications. The switch can be actuated by a mechanical, electrical, or magnetic force, and the adjustable pressure that is necessary for activation can be tailored to fit different needs. The switch is also designed to endure vibration, shock, and extreme temperatures.
