The SI2010 was developed by switch-it and is regarding to its mounting-measures compatible with the Hartmann-series 107 and 164. It stands out due to its precise switching-system as well as to its high vibration- and shock-resistance. The SI2010 is deliverable with two different types of housings and optionally with different standard-levers. Exits for strands and cables are selectively available to the left, to the right or to the bottom. Alternatively are 6,3 x 8,0 mm faston terminals possible. Into the mounting-holes are brass-bushings additionally embedded to ensure an optimal tightening torque.
