Programmable Illuminated PB
Specially designed contact mechanism for breaking
light welds.
Minimal contact bounce achieved with specially
designed interlocked switching mechanism.
Keylocks
Heat resistant resin used for outer housing,
inner case, and cover on wire lead models
meets UL94V-0 flammability standard and
provides high arc and tracking resistance.

Indicators
Touch
Solder lug, screw, and quick connect terminal models
meet IP67 of IEC60529 Standards at front panel (dust
tight and water protected for temporary immersion,
patent pending). Behind panel standard is IP60 (dust
tight but not water protected).
Supplement
