91MCE1-P1B

Snap Action, Limit Switches are widely used in home heating and cooling applications. These switches are designed to detect an increase or decrease in temperature, actuating a switch closure. This type of switch is most often connected to a central heating or cooling unit and is used to monitor the status of the system.

The 91MCE1-P1B is a Snap Action Limit Switch designed for high cycle applications and for use in industrial and commercial applications. This particular switch provides a single pole double break (SPDT) switch and is rated for 10 amp/250 VAC and 15 Amp/277 VAC. It is suitable for use with up to three different temperature variations and can be adjusted with a minimum temperature and maximum temperature preset.

The working principle of the 91MCE1-P1B is based on a bimetal strip that bends depending on the temperature, allowing the contacts to open or close. A temperature increase will cause the strip to expand, while a decrease will cause it to contract. These changes cause the actuator arm to move, which in turn opens and closes the contacts. This switch has adjustable tempeature settings, so precise temperature adjustments can be obtained.

The 91MCE1-P1B is suitable for a wide range of commercial and industrial applications, such as motorized stage equipment, lighting systems, HVAC controllers, vending machines, automated gates, and many other temperature-sensitive products. It is typically used for thermostat-type or limit switching purposes and can be used in panel-mounted or remote applications.

The 91MCE1-P1B is designed with a long service life in mind, and with low parts acceleration. This ensures that it remains operational even after extended use. Additionally, this switch meets UL and CSA standards, making it safe for use in a variety of environments.

The 91MCE1-P1B is a reliable, yet economical, snap action limit switch. Its construction is designed to detect temperature increases or decreases and actuate a switch closure. This makes it an excellent choice for a wide variety of commercial and industrial applications, such as motorized stage equipment, lighting systems, HVAC controllers, and many other products.
