### Question:

Is there a switch without chattering that turns ON when pressed?

### Answer:

Basic switches cannot completely eliminate chattering due to their structure.

### Explanation:

Chattering always occurs with a switch that has mechanical contacts.  
Photomicrosensor(photointerrupter), optical sensors, and magnetic proximity sensors are the products that detect without chattering.  
D2RV (with built-in reed switch) has the least chattering, but it is a basic switch dedicated to microload.

### Quick tips

Since the basic switch has a snap-action mechanism, chattering and bouncing will occur.  
It is possible to minimize chattering by increasing the operation speed, but increasing the operation speed increases bouncing.
