CPS Series Capacitive Switches

SCHURTER has launched its CPS family of push button switches with capacitive touch sensor technology inside. The switch family caters to the latest technology trend for robust momentary and latching push button switches while sporting an elegant modern look that makes them the perfect choice for use in applications wherever a high-quality aesthetic appearance plays a role. In addition to an IK rating 09 and IP rating 67, the series offers a predefined standard range with many visual and functional options to choose from. These features allow the customer to adapt the push button, or the switch in general, to their individual electrical and mechanical requirements.

The CPS series uses capacitive sensor technology, whereby a touch of the finger on the sensor area causes a change in the electrical field which in turn causes the switch to change its state; this occurs without any pressure on the actuator. The capacitive touch technology eliminates the need for any moving parts; hence, making the CPS a long-life product capable of an unlimited number of actuations. The CPS actuator expands further on actuation options with a so-called finger guide, which is designed to enhance the user experience.

The CPS series is made of high-grade stainless steel in 16 mm, 19 mm, and 22 mm diameter housings. The variable input supply voltage is 5 V_DC to 28 V_DC. Switching voltage is maximum 42 / 60 V_AC / V_DC. Switching current is maximum 100 mA. Operating temperature range is -20°C to +60°C. A wide range of illumination options, starting with the selection of a ring illuminated or area illuminated version, is offered. The area illuminated version is made of scratch-resistant biocompatible ceramics. A single color, bicolor, or multicolor configuration is possible. Besides the basic colors red, green, and blue, the CPS also offers additive colors like cyan, magenta, yellow, and white for custom color variations.
