Toggle switches, such as the 7202B, are electromechanical devices used to control a number of electrical circuits. Toggle switches are operated by pressing a lever in order to open and close a circuit. The 7202B is a 2-pole, single-throw (SPDT) toggle switch with a movable contact arm and two soldering or screw terminals. The 7202B is commonly used for the following applications:

Instrumentation & Control

Instrumentation and control systems often involve the use of toggle switches, such as the 7202B, to enable different circuits in process control applications. These switches provide reliable and robust operation for heavy-duty applications and can be used to manually control circuits or signal other components.

Audio/Visual Equipment

The 7202B is also used in audio and visual equipment. In some audio applications, the switch may be used to turn a power amplifier or receiver on or off, while in visual applications the switch may be used to turn on or off a monitor or projector. The toggle switch allows the user to quickly and easily change the input or output signal without having to unplug any cords.

HVAC and Lighting Control

Toggle switches, such as the 7202B, can also be used in HVAC and lighting control. The switch can be used to turn an HVAC unit or light on or off, or it can be used to control the speed or brightness of a fan or light. The toggle switch allows the user to quickly and easily change the settings of these systems without having to access the internal wiring.

Medical and Industrial Applications

The 7202B toggle switch can also be used in medical and industrial applications. In medical applications, the switch can be used to control electrical devices such as a ventilator or other medical equipment. In industrial applications, the switch can be used to control the power supply of motors or other devices. In both cases, the toggle switch allows the user to easily and safely control the power supply to the device.

Working Principle

The 7202B toggle switch works by connecting two electrical conductors together. When the switch is in the "on" position, the two conductors are connected and an electrical current is able to pass between them. When the switch is in the "off" position, the two conductors are disconnected and the current is prevented from passing through them. This allows the user to quickly and easily control the power supply to the device.

When the toggle switch is turned on, the contact arm moves inwards, connecting the two conductors and allowing the current to pass between them. When the toggle switch is turned off, the contact arm moves outwards, disconnecting the two conductors and preventing the current from passing through them. This simple movement is what allows the user to quickly and easily control the power supply to the device.
