Rocker switches on-off – button – two-position

Rocker switches are small size electromechanical devices that are used to connect and disconnect various electrical circuits. 

Types of rocker switches

Rocker switches on-off differ in the number of contacts themselves and the way they are connected. There are devices that have two contacts, as well as the so-called double switches, where pairs of electrical contacts are connected. 

In addition to keyboards, push-button and toggle switches are presented in Ukraine. Their principle of operation is similar to keyboards. Each type of electrical supplies has its own electrical designation, which is known to every experienced electrician. 

Also, these devices can be backlit in different colors. 

The use of a two-position switch 

The product allows, firstly, directly power the electrical circuit. Secondly, it is used as a sensor. Third, it can serve to distribute voltage. 

When the terminals are connected, the contacts in the circuit are closed and electrical current can flow freely through the rocker switch. In the event that the terminals are in the open position, the electrical circuit is opened, and, accordingly, the current cannot pass through the device. 

When operating the product as a controller sensor, one of its contacts must be connected directly to the output of the controller, which is a computer program is designated as an input. 

Before you buy key switches in Ukraine, it should be borne in mind that some difficulties may arise during the use of these devices. One of the main ways to prevent undefined states (0 or 1) is to connect the output of this microcontroller using electrical resistance with different surfaces (or another so-called power potential). 

Electrical resistance in this case has a universal designation: it is usually denoted pull-down and pull-up resistance (translated from English - "down" and "raise", respectively). In most cases, the resistance of the pull-up or pull-down resistors can range from a few kΩ to one MΩ. If the switch is opened at the point where the resistor is connected, the voltage will remain unchanged. If the rocker switch is closed, then an additional voltage will be applied to the input, since the resistance of the switch itself will be scanty, it can even be neglected. Thus, the product can act as a voltage distributor.
