Belimo P475 : Auxiliary switch, for 1/2" diameter shafts mount

The Belimo  P475 is a non-mercury, SPDT (Single-Pole Double-Throw) damper position switch. It is primarily designed to indicate when a desired position of a damper has been reached or to interface additional control for a specific control sequence. The P475 switch is typically installed onto the damper shaft, and its purpose is to provide information about the position of the damper. It utilizes a roller ball and a mechanical switch mechanism to determine the status of the damper, whether it is open, closed, or in the process of operating.
One of the key features of the P475 switch is that it offers a non-mercury alternative. In certain applications or projects where the use of mercury is prohibited or undesired, the P475 provides a suitable solution. It ensures reliable and safe operation without the need for mercury, which may be considered hazardous in some circumstances.

The Belimo P475 damper position switch is a versatile component that helps monitor and control the position of dampers. It offers a non-mercury alternative for applications where mercury usage is restricted or not permitted, making it a suitable choice for various HVAC (Heating, Ventilation, and Air Conditioning) systems and control sequences.
