Knowing what types of switches are available will help product designers make better decisions. In this article, we'll explore Tactile, Toggle, RF, and Solid-state switches. This includes the supply voltage, power level, and frequency. Most RF switches are designed to operate at 50 ohms, although some models can operate at up to 75 ohms

Switches can be designed to respond to any type of mechanical stimulus: for example, vibration (the trembler switch), tilt, air pressure, fluid level (a float switch), the turning of a key , linear or rotary movement (a limit switch or microswitch), or presence of a magnetic field (the reed switch). Many switches are operated automatically by

A level switch will be in its “normal” status when it senses minimum level (e.g. an empty vessel). For a level switch, “normal” status is any fluid level below the trip threshold of the switch. Float-type level switches Some level switches use a float to sense the level of a liquid surface, actuating an electrical switch by the motion of the float.

There are a range of technical terms used to describe this type of level sensing technology. Optical prism, electro-optic, single-point optical, optical level switchthe list goes on. For this purpose, we will use the term Optical Level Switch. The switch operates very simply. Inside the sensor housing is an LED and a phototransistor.

Single Pole, Double Throw (SPDT) - Single pole, double throw (SPDT) switches make or break the connection of a single conductor with either one of the two other single conductors. They usually have three terminals and are commonly used in pairs. SPDT switches are sometimes called three-way switches.

Float Float level switches are sensors with an electrical contact output at a specific liquid level. Applications include level control, valve control, deaerators, condensate tanks, oil level control, drip legs, and boilers. A few models are designed for the automation of pumps, specifically filling and draining of tanks, wells, and reservoirs.
