Snap action, limit switches, such as the WLGL-K51-N, are single-pole, single-throw devices capable of breaking or making an electric circuit at a specific point of operation. These switches are used in numerous applications in industrial, commercial, and residential settings where controlling of a circuit is desired in order to provide user protection, equipment protection, or even reduce costs.

The WLGL-K51-N switch is specifically designed for use in harsh environments, such as where corrosive liquids and gasses may be present. It is an industrial-grade device featuring a heavy-duty, dielectric shell that is capable of withstanding up to a 1.5KV surge of direct current as well as extreme temperatures ranging from -20 to 130 degrees Celsius. It also features a dual-stage action, meaning that it requires both physical and electrical input to actuate the switch, helping to ensure reliability in the switch operation.

In terms of application fields, the WLGL-K51-N switch can be used in the automotive, security, MALDI (Matrix Assisted Laser Desorption/Ionization), robotics, heating, ventilation, and air conditioning (HVAC) industries. It can be used in safety devices as well, such as circuit breakers, fuses, and relays. In some of these applications, it is used to help detect if a mechanical device has gone beyond a set point and then actuate a circuit to control the motion of the device or to turn off power to it. In others, it is used to detect the presence of water, oil, dust, or other substances to prevent hazardous situations.

In terms of working principle, the WLGL-K51-N is a snap action device. This means that when a predetermined threshold is reached, the switch changes its state from an on or off position almost instantaneously. This typically happens when either an electrical current or a mechanical force is applied to the switch. The threshold point or “snap” is pre-set by the manufacturer.

The WLGL-K51-N also features a dual-stage actuator, which means that two forces must be applied before it will change states. This helps to ensure that the switch will reliably perform its job. The first force is a mechanical actuation force, which is applied to a plunger on the external side and is then transmitted to the internal side of the switch through a hardened steel button.The second force is electrical, which is applied when the voltage of the current drops below a specific threshold. This electrical force will push on the plunger, overcome the mechanical actuation force, and cause the switch to change states.

The WLGL-K51-N switch is an ideal choice for a range of industrial, commercial, and residential applications requiring reliable switching of circuits. It has a rugged dielectric shell that can withstand hazardous environments and a dual-stage actuator for reliable operation, making it a versatile and reliable switch for any application where high-level control of a circuit is desired.
