Flat Scratch-Resistant Capacitive Microwave Oven Membrane Switches
Capacitive touch screen
Capacitive touch switch combined normal panel and capacitive sensor together.Unlike traditional push-button switches, capacitive switches don’t need press, only put finger on the button in the sensing area, can be recognized by the machine through the film sensor operation.
Electrical performanceWire Resistance | <1Ω/cm | Working current | ≤1mA |
Working Voltage | ≤6.5V | Touch resistance | ≤100mΩ |
Insulation Resistance | ≥100MΩ | voltage resistance | 250VAC，1min |
Working temperature | -20~80℃,RH95% |
Most of the buttons are made by acrylic panels or injection parts with backlight display function which has a good appearance.
Capacitive keypad has a fashionable appearance and long service life, so it has great advantages in many applications such as smart home appliances, cars, mobile phone communication, medical instruments and toys.
How does it work?
Induction capacitance exists between any two conductive objects.
A key, namely a solder pad can also constitute an induction capacitance with the ground.
The value of the induction capacitance is a small fixed value under the condition that the surrounding environment remains unchanged. A tension is normally applied on the four angles of the panel and it is uniformly widespread on all the surface of the screen;
When human fingers are close to the touch button, the inductive capacitance formed by human fingers and the ground will increase the value of the total inductive capacitance.
Capacitive touch key IC will output a certain signal when it detects that the inductive capacitance value of a key has changed. As there is no mechanical structure for the capacitive touch key, all the detection is a small change in the electric quantity, so it is more sensitive to all kinds of interference.
Therefore, the design of the sensor and the selection of touch IC are very critical.
Topflight capacitive touch switches can be produced in polyester or other film materials, and they allow a wide freedom to the designer for any type of graphic solutions and for a backlighting of great impact and effect.
When you order your custom capacitive switch from Flexkys, it ships complete with the sensor circuit, decorative graphics and your desired touch surface.
We can also provide your capacitive switch with or without the front panels.
