Today, CAPTRON offers a wide range of capacitive SENSORswitches for various industries and applications where unconditional reliability, durability, comfort and design are required. For starters, there are no mechanical components in a capacitive switch, resulting in a longer lifespan when compared to their mechanical counterpart. Most capacitive switches feature three layers: an upper graphics overlay layer, a circuit layer (flexible printed circuit or printed circuit board), and a backer layer. It works in the same manner as a typical capacitive smartphone: when you touch the surface — assuming you aren’t wearing gloves — a small electrical charge is transferred from your body to the switch, which subsequently causes a change in capacitance. 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. Another key benefit is that electrodes can be formed from any conductive material (conductive cloth, FPCB, metal fixtures) giving our sensors a wide range of design flexibility. 875C sensors are shielded and housed in a nickel-plated brass barrel. Touch Switch is available in the following finishes: reflective, piano black, white, and transparent. Works without touch when a conductive object, such as a finger, enters the field. Sensing distance is based on the type of material being sensed. Free shipping . Additionally, capacitive switches can withstand some of the harshest environments, including outdoor environments.
