h3>Types of Membrane Switches
A membrane switch is a momentary on/off switch for many different circuits. Membrane switches are thought to be momentary because they operate normally open, push to close, and immediate opening conditions. What this means is that once the switch is pressed, the two poles within make contact to close the circuit. Membrane switches are used in many industries, ranging from medical and commercial applications to consumer markets. Membrane switches are made by printing silver or carbon ink onto polyester film and then an overlay is applied to the first surface as the graphics interface.
There are two types of membrane switches: tactile and non-tactile. A tactile membrane switch relies on the user’s touch to connect the switch and underlying control panel. When pressed, the user may feel a snap of the switch. Tactile switches are used for instruments, interface control-panel applications, and keypads.
A non-tactile membrane switch is intended for more durable applications because of construction and ability to withstand external elements. Non-tactile membrane switches that are constructed of copper flex are typically produced using Kapton as the base material. Like tactile membrane switches, a non-tactile switch can be used in keypads, both with and without graphics overlays. A non-tactile membrane switch does not provide feedback like a tactile membrane switch does, therefore, they often include audio and LED indicators or display changes when pressed.
Custom Membrane Switch Design
A membrane switch manufacturer will work closely with you and your business and offer expert advice, support, and recommendations for your customized products. Integrating custom components to your membrane switch can add significant functionality while enhancing the user’s experience. Some of the more common components for custom membrane switches include a backlight and visual feedback, graphics overlaying and support panels.
Custom membrane switches can include, but aren’t limited to:
- Touch-screen panels
- Custom keypads
- Membrane switch panels
- Instrumentation panels
- Rubber dome switches
- Custom front panels
- Dome switch keyboards
- Industrial keypads
- Membrane switch keyboards or keypads
Functionality is crucial when it comes to membrane switches. With that said, creating custom membrane switches ensures your devices function properly to meet all your needs. Custom Membrane Switches can be used in many industries and offer options for appliances, keypad inputs, controllers, instrumentation overlays and medical devices. Find a membrane switch supplier with a reputable history that can help you create the right product for your personal and business needs.
