High Security Keylocks
Rockers
Distinctive Characteristics
Pushbuttons
High insulating material for 16mm CKM models withstands
over 15 kilovolts of electrostatic discharge, thus providing
antistatic feature.
Vertically rotating switching mechanism combines with
self-cleaning sliding contacts for high reliability and
long operating life.
16mm and 19mm diameter bushings available.
F
Rotaries
CKL and CKM on-off-on models with tubular keys have
push-and-lock mechanism which allows contactor to drop
and slide over stationary contacts.
Keylocks
Programmable Illuminated PB
Rugged, die cast housing 19mm CKL models designed for
higher security requirements.
Slides
Available in both flat and tubular key styles; flat key is
reversible for easier setting.
Tactiles
Epoxy sealed terminals prevent entry of flux and other
contaminants.
Actual Size CKM with Tubular Key
Tilt
Interior construction provides seal for contact area.
Supplement

Standards & Certifications
The SK Series devices have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.

Distinctive Characteristics
Pushbuttons
Housing and bushing of high insulating material withstands over 15
kilovolts of electrostatic discharge, thus providing antistatic protection.
Programmable Illuminated PB
Totally sealed construction with internal o-ring, with gasket
between base and housing, and with insert-molded terminals,
gives protection for automated processing techniques.
Subminiature size allows high density mounting.
Molded-in terminals prevent entry of flux and other
contaminants.
F
Rotaries
Crimped bracket legs ensure secure PCB mounting and
prevent dislodging during automated wave soldering.
Keylocks
Antistatic Process Sealed Keylocks
Tactiles
Slides
Bifurcated, self-wiping contact mechanism provides
unequalled logic-level reliability and smoother,
positive detent actuation.
Detent mechanism, with its spring-operated steel ball, gives
distinct feel and crisp actuation for accurate switch setting.
Tilt
.100” x .100” (2.54mm x 2.54mm) terminal spacing conforms
to standard PC board grid spacing.
