Cherry Brand DK Series High Performance Sub Subminiature Switches are Sealed to IP6K7 for Challenging Environments

2009 LOGO.jpg

The Best Switches Come In Small Packages

Leading designer and manufacturer of switches, sensors and controls, ZF Electronics, has launched a new series of sub subminiature switches which suit applications as diverse as automotive door latches, industrial locking systems, outdoor equipment and hand-held control units.  Demands on electronic components for increased reliability and functionality increase year on year, together with the need to achieve higher specifications within ever-shrinking housing sizes.  The new DK sub subminiature series from ZF Electronics provides the smallest dimensions and highest performance for a snap switch in its class.

DK switches are less than 15mm in length and are sealed to IP6K5 (IP6K7 on request) for use in wet or dusty environments. With temperature ratings of up to 105degC, they are extremely reliable, with a long mechanical life of over 500,000 actuations. Additional actuators are available in a choice of either simulated roller or plain stainless steel and can be operated vertically or via customised actuators.  DK switches offer long over-travel features (1.3mm minimum) and have a variety of connection possibilities with solder, PCB terminals or pre-wired options all available.

Standard DK sub subminiature switches are designed for use on low-voltage DC circuits – nominal current rating is 5mA up to 2A. Non-standard versions are also available for circuits up to 60VDC, for example for use in battery-powered equipment.  Very low voltage applications are also possible, such as the switching of thermo-couples.  Contact configuration is single pole, dual throw (SPDT) with the benefit of AuAg crosspoint contacts for high contact stability. DK series switches can also be ganged for multiple use.

Cherry Electrical Offers New DZ Range of V4 Sub Miniature Switch, Available with Positive Break Action

 2009 LOGO.jpg

Cherry Electrical Products’ new range of V4 sub miniature DZ switches offers a Positive Break Action feature. This mechanism operates when the contacts are welded or clotted and the operating force is insufficient to open the contact. In addition, parts consist of cadmium-free contact material in accordance with RoHS directives.


The DZ range operates at temperatures between -20 and 85degC, with a contact resistance of less that 100mΩ between 100mA and 10VDC. The device switches high inductive loads 3 (3)A 250 V at 50,000 cycles and complies to standard EN 60335-1 for resistance against heat and fire.

DZ switches are especially designed for motor drives (sun blinds; adjustable beds, armchairs and office desks; automatic doors and gates…). Devices are also applicable as limit switches for industrial automation, and as auxiliary switches for medium-voltage systems.
