TA / LT Series push button switches offer an “ultra-lite”
alternative to design engineers working in a variety of
applications. Available features include:

• Spring loaded, wiping contacts for smooth, silent
actuation stroke and excellent reliability

• Up to 16 poles per module

• Mounting chassis available.

• Interlocked assemblies up to 20 stations

• Optional terminal length

• Snap-on buttons

• Solder lugs on top for hand wiring; PC at bottom for
flow soldering

• Switch plunger with sliding contacts can be removed
from the front without disturbing electrical connections.

• Fixed terminals are epoxied and “staked” in position,
providing an extra seal to help prevent wicking of solder
or flu x .
