Combined electrical switch and fluid power control device

A combined fluid power and electrical control device, comprising

• a casing having front and rear walls and a plurality of side walls,
• said casing having an opening therein extending through and between said front and rear walls,
• an operating lever extending through said opening and movable therealong,
• said lever having a rear portion to the rear of said rear wall,
• said casing having means to the rear of said rear wall and pivotally supporting said rear portion of said lever to support said lever for swinging movement in said opening,
• said lever having a front manually operable portion projecting forwardly from said front wall of said casing,
• said lever being swingable in a plane generally perpendicular to said front and rear walls,
• said plane being generally parallel with one of said side walls,
• a carriage slidable in said casing,
• means in said casing and guiding said carriage for sliding movement along a path parallel with said front walland also with said one side wall,
• said carriage having one particular side which is generally parallel with said one side wall of said casing, a pin-and-slot driving connection between said lever and said one particular side of said carriage for translating the swinging movement of said lever into sliding movement of said carriage,
• a slidable valve member in said casing and to the rear of said carriage,
• means in said casing guiding said valve member for sliding movement along a path which is adjacent and generally parallel with said rear wall and transversely related to the path of said carriage,
• a cam-and-follower driving connection between said carriage and said valve member for translating the sliding movement of said carriage into the transverse sliding movement of said valve member,
• valve port means on said rear wall and cooperating with said valve member to perform fluid power control functions in response to the sliding movement of said valve member,
• fixed electrical contact elements in said casing and on said front wall adjacent the path of movement of said carriage,
• and movable electrical contactor means on said carriage and selectively engageable with said fixed electrical contact elements for performing electrical control functions in response to the sliding movement of said carriage.
