Snap action switches are mechanical devices used in a variety of applications to detect changes in position, vibration, and temperature. The AH7455559-A range of snap action switches is designed specifcally for temperature sensitive applications, providing reliable operation up to 250°C. These switches use a patented contact system which enables reliable operation in even the harshest environments.

The switches work by detecting changes in the ambient temperature, via an internal thermal element. These switches feature a high temperature ratating of 250°C and can be used for a wide range of applications such as industrial process controllers, chemical process controllers, appliance over temperature protection, enclosure over temperature protection, and more.

In operation, the switch body is made up of three components: the contact block, spring and actuator. When the temperature of the ambient environment exceeds the preset temperature threshold, the actuator will move toward the contact block, which causes the spring to be compressed. This action changes the position of the contacts, triggering the switch to activate or de-activate.

The AH7455559-A series of snap action switches are ideal for use in industrial environments where long life cycles and reliable operation is required. The switch body is made of stainless steel, with silver chrome contacts for increased performance, providing reliable operation for high temperatures up to 250°C. The switch has a total of 8 switch models, each rated for different current and voltage ratings, making this range of switches ideal for a wide variety of applications.

The snap-action switches from this range are also extremely flexible, with a wide range of options for customization. They offer standard configurations such as normally open and normally closed, but can also be configured for dual action switching, as well as for use in “latching” or “non-latching” applications. They are also highly customizable when it comes to their contact arrangement, with the AH7455559-A range offering options for single pole, double pole and 4-pole versions.

The AH7455559-A range of snap action switches are designed to be reliable and long lasting, with a very high temperature rating which makes them suitable for many industrial applications. Their flexibility and customization options also make them an ideal choice for a variety of applications.
