Manufacturing a Reliable Custom Capacitive Switch

What is a Custom Capacitive Switch? A custom capacitive switch senses touch through capacitance changes. When you touch a capacitive switch, the electricity stored in your body interacts with conductive material in the switch. The switch senses the resulting change in capacitance and reacts according to its programming. Capacitive touch technologies are becoming increasingly popular, Read More …

Ag/AgCl (Silver Silver Chloride) Screen Printed Electrodes

Screen printed electrodes are revolutionizing the way that we collect data and measurements. Ag/AgCl (Silver Silver Chloride) reference electrodes are the industry standard reference electrode for many electrochemical measurements. This is because Ag/AgCl electrodes have a stable electrochemical potential in a variety of different measurement conditions. Almax manufactures custom Ag/AgCl screen printed electrodes by printing Read More …

Wearable Electronics

One of the hottest new areas of growth in printed electronics is wearable electronics. New technologies are enabling highly conductive electronic circuits that are flexible, soft, and durable and can be machine washed, all for low cost. This includes markets for wearable health sensors, consumer electronics, and sports. The wearable electronics industry is growing fast Read More …

Membrane Switch Durability

A membrane switch gives a visually pleasing human-machine interface that is easy to use, low profile, and electronically stable. They are well known to stand up to harsh conditions. Flex circuitry is resilient and can be used in many different environments. Once you know what the end use will be for the flex circuit, the Read More …

Metal Tactile Domes for Membrane Switches

We use metal, tactile domes in our flex circuits and membrane switches. Tactile domes are placed onto the Polyester/Polycarbonate substrate with pressure sensitive adhesive tape (Peel-N-Place Array) or captured in a membrane-type pocket design. Metal Touch switches are pressure activated, which prevents accidental actuation by environmental factors and are effective with gloves and styluses. Capacitive Read More …
