Ruskin L120-S 2-Position Spring Return Actuator 177 lb-in 120V W/Auxiliary Switch

The Ruskin L120-S is a 120-volt, two-position spring-return auxiliary switch that plays an important function in a variety of HVAC systems. This small and adaptable part uses its 177-inch-pound torque to turn on or off equipment according to preset settings, much like a silent on/off switch. Consider it as a guardian overseeing the regulation of intricate HVAC systems. It can be included in dampers, air handlers, and other equipment to initiate functions such as airflow adjustment depending on temperature readings, ventilation fan activation, and heating/cooling mode switching. An additional crucial layer of safety is provided by the spring-return mechanism, which makes sure the switch automatically returns to its initial position when the power is turned off. For both homeowners and HVAC experts, the L120-S has many advantages.
