INDICATOR PUSHBUTTON KEYLOCK SELECTOR
Product Profile
The Series 71 is a high quality, modular
switch range that includes pushbuttons,
indicators, selector switches and
keylock switches in flush mount with self
cleaning snap-action switching
elements. The switching elements may
be soldered directly onto the PCB and the
actuators are lockable with an
interlocking pin, no spacing pins needed.
