Snap Action Limit Switches

Snap action limit switches are used to indicate when a given threshold of travel or force is exceeded on any given device. Snap action limit switches are typically used when precise control is required over the switching of a mechanical device. They can be used to indicate when an actuator is reaching its destination limit, when a trigger has been activated, or when a manual calibration function has been completed.

The snap action limit switches are designed with a metal armature which actuates a pair of contact sets. When the metal armature reaches its given threshold of travel, the contacts close or open to indicate the presence of the switch. This configuration allows for the switch to provide a reliable indication when the given threshold has been exceeded.

The 44505-1112 is a particularly popular snap action limit switch due to its versatility. This model is typically used in applications such as air conditioning and refrigeration systems, elevators, and conveyor systems. The limit switch operates on a single-pole double-throw (SPDT) configuration and is powered by a common 10 amp T-rated thermo fuse. The switch has an operating current of up to 6 amps at 230V AC.

The operation of the 44505-1112 is fairly straightforward. The operation of the switch is controlled by the action of the metal armature. When the metal armature exceeds the given threshold of travel, the contacts close, opening the switch and providing an indication of the switch’s activation. This action can be used to indicate when the given threshold has been exceeded on any given device, or to indicate the completion of a manual calibration.

The 44505-1112 is available in both single- and double-throw configurations, allowing for a greater range of operations from a single device. This makes it an ideal choice for applications where precise control over the switch is required and for applications which demand a higher level of reliability.
