Electronic displays are everywhere – at the gym, in your home, in your car and on billboards. They are primarily used to display information in a form that it can be seen, even in the dark. Electronic displays come in both analogue and digital form. These devices can display digits and alphanumeric characters. They are often referred to as segment displays because they comprise segments which can be turned on and off to display desired information. Continue reading

Solenoid valves, or solenoids, are devices that convert electrical energy to mechanical energy, thereby creating a magnetic reaction; this occurs every time an electric current makes its way through the wire in the solenoid. When a device is forced into motion, the solenoid activates it. These devices are usually used to power fluid and hydraulic systems.

Solenoids have different functionalities; they can be used to start your car or activate your sprinkler system Continue reading

Pressure sensors are usually used to measure the pressure of liquids or gases.  These devices act as transducers which convert energy from one form to another; they use the pressure of the liquid or gas to generate a signal. Pressure sensors can also be used to measure variables such as fluid flow, speed, and water level. There are different types of pressure sensors which have different functions in production. It is important to select the right pressure sensor for your application so that it can function optimally and stand the test of time. Continue reading

Liquid level sensors are useful devices with a very important function in industrial industries; they ensure that all processes and operations in these industries function as they should, without a glitch. The main purpose of a liquid level sensor is to monitor and control the level of liquids in huge tanks and vessels. Continue reading

What Are Proximity Sensors?

Proximity sensors are electronic devices that detect the distance of an object in relation to the sensor itself. These devices use electromagnetic radiation to detect how far or near an object is, and then they send out a signal. Proximity sensors are great because they are reliable and have a good life span; they require little to no protective maintenance. Continue reading

Industrial speed sensors are useful devices that monitor and signal the speed, direction, vibration and temperature of a rotating shaft; their purpose is to ensure that the shaft isn’t rotating too fast or too slow, which could cause damage to the machine. There are different types of industrial speed sensors available in the market; each speed sensor is equipped with either a digital or analogue signal output. Continue reading

Rotary encoders are electromechanical devices that are commonly used in automated industrial machinery and on servomotors. These devices are sensors that track the rotation of motor shafts and generate information regarding the digital position and motion of the motor shafts; the information gathered is converted into an analogue or digital code. Continue reading

An isolation switch is a manually operated mechanical switch which electrically isolates a circuit from the main power; it helps to ensure that there is an efficient distribution of power. This switch can be used to add more power to your vehicle as it separates your primary battery system from your auxiliary battery; the isolator enables you to use accessories such as winches without affecting the power in the primary battery. Continue reading

Level indicators are devices that are used to detect the level of liquids, powders and granular materials. These devices are used in numerous environments from small containers to lakes. There has been a significant advancement in sensor technologies; they are easy to use and portable. A liquid level sensing device can be placed on the wall of a container and within seconds an exact measurement will be displayed. Below we take a look at 3 different level sensors and their various applications. Continue reading

Home and business owners who operate generators will understand the functional importance of Automatic Transfer Switches. Continue reading

The current electricity crisis in South Africa has resulted in many home and business owners considering alternative options. As we can no longer rely on an uninterrupted power supply from our utility company, we must find a sustainable solution. The use of solar power has been viewed as the best solution as it is a renewable source of energy that is ideally suited to our sunny climate. Switches International recognises the need for the availability of solar supplies. As a result we stock all the necessary solar requirements for your convenience. Continue reading

A solar inverter is an electronic device that is an essential component in a photovoltaic or solar PV system. The solar panels absorb sunlight and the solar inverter changes the electric current from DC to AC. As a result, the inverter allows the energy generated from sunlight to be used to power electronic appliances and systems. Continue reading

Switches supply an extensive range of load cells from single point to spoke-type and tension link. But what is a load cell and what are their uses?

Load cells are used in a number of industries as a standard weight measuring device. Also referred to as strain gauges, these devices are able to measure a mechanical force like tension or compression and convert the measurement into an analogue or digital reading. When a load or weight is applied to a structure, the sensing element changes, from the use of an internal transducer, a measurement of weight can be recorded. Continue reading

A hygrometer or humidity sensor is a device that is used to measure the moisture content in an environment. Humidity measurement instruments usually rely on measurements of a quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity. Humidity sensors are used in both commercial and domestic environments.
