Siemens Building Technology 151-147, Positioning Switch Surface Mounting Kit

Description:

The SW 151 Positioning Switch (standard type) is used to deliver any manually selected pressure over a range of 15 psi. It has a wide variety of applications in pneumatic control systems. The adjustment knob can be turned approximately 300 degrees. The bleed type switch changes the outlet pressure 3 psi for 300 degree knob rotation. The primary use is for manual reset of the RC-195 Receiver-Controller. Several mounting arrangements can be used. Switches may be mounted on control panels with descriptive name plates, surface-mounted on a wall or duct, or placed directly on control center panels by omitting the dial faceplate. When the dial faceplate is omitted, an inscription covering switch function is made directly on the panel itself. The switch has a small body diameter which permits close center-to-center mounting. It can be used with panels up to 3/8-inch thick. Three standard dial plates are available. A blank plate is also available which can be printed to order. A nomenclature plate is provided with space for indicating switch operation. The positioning switch has solid brass body parts for maximum resistance against corrosion. In addition, a transparent face cover protects both the dial and nomenclature plates.
