Switch Debounce

The schematic illustrates a 50W power supply providing a 5V, 10A output. It operates as a flyback converter in continuous mode. The circuit incorporates both primary and secondary side controllers, offering full protection against fault conditions such as overcurrent....

This circuit is a touch switch circuit, similar to a touch door alarm. It utilizes a 555 timer as the core component of the touch switch circuit. The operation begins when the plate is touched, triggering the 555 timer....

SI and S2 must be pressed within 200 ms of each other to activate K1. The hold time is adjustable via K7. Additionally, the overlap time of SI and S2 can be modified by changing C1 and C2 or...

The Dragon ZL-2801A is a DVD machine that utilizes a switching power supply circuit. The circuit primarily consists of an AC input circuit, a rectifier filter wave circuit, an oscillation circuit switch, a switch transformer (Tl), a secondary rectifier,...

The light-activated switch circuit can be used for switching off a particular lamp or group of lamps in response to varying ambient light levels. The light-activated switch circuit utilizes a light-dependent resistor (LDR) as the primary sensing element to detect...

The whistle switch features two tone detectors, each based on an LM567 tone decoder, requiring minimal additional components. It is designed to respond to two or more occurrences of a specific tone or sequence of tones within a defined...
