TERMINALSEAL: High strength bonding red resin
RELEASE BAR: Steel / zinc plated
• 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 .
