Designed to be the most adaptable
switch on the market, the 69J offers the

mounted on the front or either side, and
can be rotated to any of eight different
positions allowing for quicker assembly
and shorter tubing. Bottom cable entry
is also available with unique built-in
clamping strain relief for even quicker
assembly. With thousands of variations
right off the production line, the 69J pro-
vides maximum flexibility at minimum
cost. With UL, CSA and CE approvals,
the 69J is designed to be sold anywhere
in the world.
