Sealed rocker switches

Apem has revealed the new KR family of sealed rocker switches. With their large actuator surface, they are designed for applications requiring switches to have an attractive style, superior feel and high reliability. The KR is ideally suited for applications in the marine markets.

Single- and double-pole models are available in an extensive range of electrical configurations, including ON-OFF, ON-ON, ON-ON-ON and ON-ON-MOM. This switch is rated up to 15 A at 12 V d.c. for 10 000 cycles. Additional electrical specifications include initial contact resistance of 10 mΩ, insulation resistance of 1000 MΩ at 500 V d.c. and dielectric strength of 2000 Vrms between terminals.

The KR series is available with solder lug/quick-connect and screw terminals and with or without a plastic barrier between terminals. Up to 10 terminals are offered to allow for multiple electrical and illumination possibilities. Materials include silver contacts and UL94-VO rated engineering plastics. The switch is designed to be mounted into a 37 x 21 mm panel cut-out.

The rocker switch can be customised to fit specific applications. It features custom marking and illumination with laser engraved legends. Lighting options include 6, 12 and 24 V d.c. LEDs available in red, green and yellow. Actuators are available in nine standard colours and custom colours can be produced for unique applications. A mating connector and wire terminations are also available to simplify installations.
