The ability for an electromechanical switch to produce a distinct sound is a growing trend in many requirements. However, designers requiring this option have been at the mercy of the inherent actuation sound of the switch they specify, or must produce the desired sound by re-engineering the devices using membranes, casings, or other filtering products — a costly and time-consuming venture when considering trying to match the numerous switches in, for example, an automobile.
The KSC ST series sound-tunable tactile switches, available from Switches Plus Components , use selected materials to enable control of sound intensity levels. The result is that electromechanical devices can be tuned from high (>50 dBA) to low (<30 dBA) levels and ensure sound continuity from switch to switch. The tactile switches come in an SPST normally open configuration with J or G terminations.
Following are the features and benefits of KSC ST sound-tunable tactile switches:
- Positive tactile feeling
- Range of 2 sound intensity
- J or G terminations
- IP 67
Typical applications of KSC ST sound-tunable tactile switches include:
- Automotive
- Industrial electronics
- Keyboards
- Medical equipment
