US Patent 9926135 Externally controlled switch mechanism

A control mechanism for a refuse vehicle includes a first control valve that operates a first hydraulically controlled mechanism and a second control valve that operates a second hydraulically controlled mechanism. The control mechanism also includes a plurality of switches and a pneumatic control mechanism. The plurality of switches generates a valve select signal and a mode signal. The pneumatic control mechanism selectively controls the first control valve and the second control valve based on the valve select signal and the mode signal. An operator of the refuse vehicle actuates the plurality of switches while the operator is operating the pneumatic control mechanism.
