Capacitance attenuators posses no mechanical parts which could lead to a functional failure due to damage, freezing, or wear and tear. They can provide pulse, momentary, and latching action. The lifetime of capacitance attenuators is nearly unlimited, at greater than 50 million cycles. Actuation is by touch to he front side.
Capacitance attenuators can be sensitive to water, dirt and EMC. The electronics of the CSE incorporates an adaptive function that is slow to change. For example, dirt particles and water drops are registered and disregarded by the actuator, thus avoiding unintentional actuation or function failure.
The CSE is available in two different types: the CSE 16 (mounting hole diameter) and the CSE uG ("under glass"). The CSE 16 is a flush mount beveled actuator, made up of anodized aluminum. It is fastened to the front panel with an M16 × 1 nut. An O-ring ensures an impermeable seal. It features ring illumination in red or green. The actuator can be permanently illuminated, or it may be connected to a switching signal. The CSE uG is a square switch with a LED in each of the four corners. Its actuators and switches can be installed under a non-conductive overlay material of up to 20 mm thickness, such as glass, wood or tile.
