When purchasing a light touch key switch, customers will consider how to filter out a good light touch key switch, so how to choose a light touch key switch?

The light touch key switch is a new generation of photoelectric switch components produced by using integrated circuit chip technology and SMT surface equipment processing technology. The role of intelligent systems such as diagnosis.

1. Look at the touch  

Most power switches of good quality are made of high-grade raw materials such as EXO glue. They have high fire safety performance, waterproof performance, anti-collision performance, etc., and the surface is smooth. Power switch material and know the agent. Generally speaking, products whose surface is not smooth and feel thin and brittle cannot be trusted in various performances. The control panel of a good outlet switch stipulates that there are no air bubbles, no scratches, and no stains. The touch of the power switch button is light and not tight, the socket of the power socket needs to be equipped with a maintenance door, the power plug should be inserted in a certain range, and one foot cannot be inserted into the button switch.

There are single-stage double-position switches or double-pole double-position switches. According to the mechanical energy and main purpose, they are divided into start buttons, calibration buttons, inspection buttons, manipulation buttons, and limit switch buttons. 

Buttons are divided into moving on (open and off) and moving off (normally closed). 

Small keys use conductive glue or copper sheets as electrical conductors, which can be used as status switches for small and medium-sized semiconductor material recorders, controllers, money detectors and other commodities. Analysis and explanation of key switch  

The key switch is a low-voltage switch household appliance used to disconnect and connect to the control circuit. The circuit breaker of the key switch is rated at 5A. Therefore, the power supply circuit manipulated by the actual operation of the key switch belongs to the small current power supply circuit.

2. Look at the appearance 

Touch the button to switch the power switch. The appearance and surface should look smooth. The electroplating process also needs to be bright and clean, and it also needs to emit light under natural light.

This kind of novel photoelectric switch is a kind of active optical detector type switch element that selects pulse modulation. The applied cold light lamps include infrared light, red light, emerald green light and dark blue light. Quickly and manipulate the situations and gestures of a wide variety of solid, liquid, crystalline, bold, soft, and smoke chemicals. Promoting moisture-proof and explosion-proof switches Capacitance grid limit switches have defects such as low response time, poor precision, easy damage to the inspected object and short cycle for touch inspection. Metal Material. However, the new photoelectric switch gets rid of the above defects, and has small size, many functions, long service life, high precision, fast response time, long inspection distance and strong resistance to light, electricity and magnetic interference.
