V-Series Contura Switches
The V-Series Contura II, III, IV and V snap-in rocker switches offer countless unique options including:
- Choices for ratings, circuits, colors, illuminations and symbols.

- Removable actuators in a choice of actuator styles and colors,
- Square or bar shaped lenses.
- Optional plug-in terminal connector enables pre-wiring of wire harness.
- Asymmetrical "orange wedge" curved actuator affords new mounting options including half-moon, triangle, pyramid or stack.
- Sealed front panel components, are certified to IP66 and IP68, signifying complete protection against dust and prolonged spray and submersion under pressure
- Recognized to UL1500 - Ignition Protection for Marine Products.
- Vibration, shock, thermo shock, moisture and salt spray resistant.

Rotary Switches
Rotary switches C-, CA-, CL-, and CAD-series offer a solution for most cam switch applications. They can beused as control, instrumentation, or motor switches and can also be used in electronic circuitry and aggressive environments.
The cam-operated L-switches are continuous current rated for off-load switching. They may be used to switch resistive or low-inductive loads.
The classic Kraus & Naimer C-series offer an ideal solution for a wide variety of aplications with specific models for all current ratings.
The CA-series with finger proff terminals from 10 A to 32 A is ideal for applications where industrial controls, instrumentation and electric motors are involved. The CA4-1 has gold-plated contacts and guarantees reliable switching under any conditions.
Finger-proof terminals are accessible either horizontally or vertically.
Other Switches
On/Off Battery Switch has a 350A continuous rating for applications requiring high power output, reliablilty, and low heat generation.
Four Position Battery Switch has a 350A continuous rating for applications requiring high power output, reliablilty, and low heat generation.
Pushbuttons are available in round, square, and rectangular shapes; in various colors; and with or without illumination.
