Thus the electronics board is not exposed 
to mechanical loads, making the LEHLE 
PARALLEL SW II virtually indestructible 
and guaranteeing years of trouble-free 
switching.
The LEHLE PARALLEL SW II has three op-
erating modes, making the switch work 
as either a latching or momentary switch, 
allowing for short or rhythmic stutter-ef-
fects. 

The third mode combines a mixture of 
operating mode one and two: a short hit 
is latching, a long hit is momentary.

Placing no limitations on your creativity!
We take care of your signal so that you 
can take care of the music.
