Pushbutton Relay Selector
This circuit is designed for use in a hi-fi showroom, allowing a selection of speakers to be connected to a stereo amplifier for comparative purposes. It can also serve similar applications where only one device from an array needs to...
A relay control circuit
A relay control circuit is illustrated, which is commonly found in microwave switches. This circuit facilitates the operation of various components such as the power supply switch, electric fans, light bulbs, food turntables, and timers. The relay control signal circuit...
light activated relay
This circuit is similar to the previous one but incorporates a photoresistor to trigger the flip-flop instead of a push button. A bias resistor is placed in series with the photoresistor to ensure that adequate voltage is present at the...
Low Voltage Supplies - Solid State - Tubes
Such supplies are often realised with dedicated integrated circuits nowadays but it's still interesting to give a look at old designs to understand the basics.
The description outlines the evolution of power supply designs in electronics, emphasizing the transition from traditional...
zener Flyback diodes issues and pull-in & hold current issues in this Relay circuit
Although this may be a basic question, there is still some struggle with it. In this schematic, two zener diodes D1 and D2 are connected back-to-back across relay coil L1. The breakdown voltage (BVds) is -30V for Q1. The question...
Buick LeSabre
This line provides ground to the relay and is normally open (N-O) when the control unit (CU) is OFF, and is normally closed (N-C) for all other control functions. The OFF switch on the CU is "sticky." Several questions arise:...
Relay driver
The relay operates for a specific duration, td, after power is applied, followed by an operating time, tc. The SCR activates when the voltage across capacitor Ci reaches a threshold voltage, VA. This action energizes the relay, which remains activated...
Adjustment-free precision summing amplifier
This circuit generates continuous outputs that depend on multiple input variables.
The circuit in question typically employs a combination of operational amplifiers (op-amps), resistors, and potentiometers to achieve its functionality. The outputs can be tailored based on the variations in...
Lights-On Reminder Circuit
A relay and two diodes are all that is needed; the relay performs the job of a buzzer, so no annunciator is required. When the lights are left on while the ignition is off, the normally closed relay contacts are...
