Angle of throw (determines the maximum number of positions): 10 = 10, 36 positions 11 = 11.25, 32 positions 12 = 12, 30 positions 15 = 15, 24 positions 18 = 18, 20 positions 22 = 22.5, 16 positions 30 = 30, 12 positions 36 = 36, 10 positions 45 = 45, 8 positions 60 = 60, 6 positions 90 = 90, 4 positions. 25BSP22Q116 C Stop arrangement: For switches with maximum positions, add C for continuous rotation add F for stop between first and last. No notation required for less than maximum positions. Number of positions: Maximum is dependent on the angle of throw. Minimum is two. Number of decks: One through four possible. Code output: B = Binary (contact Grayhill for availability) Q = Quadrature G = Gray (contact Grayhill for availability) 1 Specials include /8 diameter shaft, custom angles of throw for binary, binary complement and gray code outputs.
