KMC Controls YMC-Series Pneumatic Selector and Gradual Switches

Pneumatic Selector and Gradual Switches

This series of YMC switches consists of manually actuated gradual switches and selector switches. Models depicted in photograph are shown with various scale plates.

The YMC-1001 is designed for delivering a variable, selected air pressure from the branch line to a remote device. It is used in pneumatic control circuits for remotely positioning other devices as well as remote setpoint adjustment for receiver-controllers.

Typical applications for the selector switches (YMC-2000/3000 6001 series) include diverting and supply/exhaust of pneumatic signals to other devices.

The YMC-2001/2002 models have two positions, YMC-3001/3002 have three positions, and the YMC-6001 has six positions.

Scale plates and mounting bracket are ordered separately. The bracket is available for panel mounting if desired.
